Kibana MCP Server

by TocharianOU

Kibana MCP-Server

API-Spezifikation

Dieses Projekt basiert auf der offiziellen Elastic Kibana API-Dokumentation und verwendet die OpenAPI YAML-Spezifikation von Elastic Stack 8.x (ES8), um alle Kibana API-Endpunkte dynamisch abzurufen und zu verwalten. Aktuelle Informationen finden Sie in der Kibana API-Dokumentation .

Eine Kibana MCP-Serverimplementierung, die jedem MCP-kompatiblen Client (wie z. B. Claude Desktop) den Zugriff auf Ihre Kibana-Instanz über natürliche Sprache oder programmgesteuerte Anfragen ermöglicht.

Dieses Projekt wird von der Community gepflegt und ist kein offizielles Produkt von Elastic oder MCP.

}

Beispielabfragen

  • „Wie ist der Status meines Kibana-Servers?“

  • „Listet alle verfügbaren Kibana-API-Endpunkte auf.“

  • „Details für den Endpunkt POST /api/saved_objects/_find anzeigen.“

  • „Führen Sie eine benutzerdefinierte API-Anforderung für /api/status aus.“

  • „Holen Sie sich eine Liste aller Dashboards in Kibana.“

  • „Fragen Sie API-Endpunkte ab, die sich auf Endpunktereignisse beziehen.“

Zwei Eingabeaufforderungsmodi in Claude Desktop

Bei Verwendung dieses Servers mit Claude Desktop werden zwei verschiedene Eingabeaufforderungsinteraktionsmodi unterstützt:

1. Toolbasierter Eingabeaufforderungsmodus

  • So funktioniert es: Claude Desktop kann Server-Tools (wie get_status , execute_api , search_kibana_api_paths usw.) direkt aufrufen, um Ihre Fragen zu beantworten oder Aktionen auszuführen.

  • Am besten geeignet für: Benutzer, die eine dialogorientierte, geführte Erfahrung wünschen. Der Server sucht, führt aus und erklärt automatisch Kibana-APIs.

  • Beispiel: „Alle Kibana-API-Endpunkte anzeigen, die mit gespeicherten Objekten in Zusammenhang stehen.“

  • Testtipp: Wählen Sie für Integrationstests die Eingabeaufforderung kibana-tool-expert in Claude Desktop aus und beginnen Sie dann mit der Verwendung.

2. Ressourcenbasierter Eingabeaufforderungsmodus

  • So funktioniert es: Claude Desktop interagiert mit dem Server über Ressourcen-URIs (wie etwa kibana-api://paths oder kibana-api://path/GET/%2Fapi%2Fstatus ), und der Server gibt strukturierte Daten zurück, die Claude analysieren kann.

  • Am besten geeignet für: Fortgeschrittene Benutzer, MCP-Clients, die nur Ressourcenzugriff unterstützen, oder Programmierszenarien, die Roh-API-Metadaten benötigen.

  • Beispiel: „Get resource kibana-api://paths?search=dashboard“

Hinweis: Die beiden Endpunkte in resources ( kibana-api://paths und kibana-api://path/{method}/{encoded_path} ) verfügen über entsprechende Basistools ( list_all_kibana_api_paths , get_kibana_api_detail ). Dieses Design gewährleistet die Kompatibilität mit MCP-Clients, die nicht mehrere Ressourcen intelligent auswählen können, und erleichtert Tools wie Claude Desktop die Interaktion mit Kibana.

Tipp: Den meisten Benutzern wird empfohlen, den Tool-Modus zu verwenden, um ein natürlicheres und leistungsstärkeres Erlebnis zu erzielen. Der Ressourcenmodus bietet maximale Flexibilität für erweiterte und kompatible Anwendungsfälle.


Entwicklung

Installieren Sie Abhängigkeiten:

npm install

Erstellen Sie den Server:

npm run build

Automatischer Neuaufbau im Entwicklungsmodus:

npm run watch

Debuggen

Da der MCP-Server über stdio kommuniziert, kann das Debuggen umständlich sein. Es wird empfohlen, MCP Inspector zu verwenden:

npm run inspector

Nach dem Start stellt Inspector eine über den Browser zugängliche URL für ein Debugging-Tool bereit.

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden for behavioral disclosure. It mentions 'multi-space support' which adds some context about space handling, but fails to describe critical behaviors like authentication requirements, rate limits, error handling, or what 'execute' entails (e.g., whether it's idempotent, what happens on failure). For a tool that can perform write operations (PUT, DELETE), this is inadequate.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence that front-loads the core purpose ('Execute a custom API request for Kibana') and adds a key feature ('with multi-space support'). There's no wasted language or redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity (5 parameters, no output schema, no annotations, and support for write operations), the description is incomplete. It lacks information about return values, error conditions, authentication, and how to use parameters effectively. The mention of 'multi-space support' is helpful but insufficient for a tool with this scope and potential impact.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 20% (only the 'space' parameter has a description), so the description must compensate. It adds minimal value by implying the tool handles 'multi-space' contexts, which relates to the 'space' parameter, but doesn't explain other parameters like 'body', 'params', 'method', or 'path' beyond what the schema provides. The baseline is 3 since schema coverage is low but the description doesn't fully compensate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb ('execute') and resource ('custom API request for Kibana'), specifying the action and target. However, it doesn't explicitly differentiate from siblings like 'get_kibana_api_detail' or 'list_all_kibana_api_paths', which appear to be read-only operations, while this tool supports multiple HTTP methods including write operations.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description mentions 'multi-space support' but doesn't provide explicit guidance on when to use this tool versus alternatives. No context is given about prerequisites, when-not-to-use scenarios, or comparisons to sibling tools like 'get_available_spaces' or 'search_kibana_api_paths'.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_available_spacesC

Get all available Kibana spaces with current context

ParametersJSON Schema
NameRequiredDescriptionDefault
include_detailsNoInclude detailed space information (name, description, etc.)

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It states what the tool does but lacks details on permissions needed, rate limits, pagination, or what 'current context' entails. This is a significant gap for a tool that likely interacts with a Kibana API.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence that directly states the tool's purpose without unnecessary words. It's appropriately sized and front-loaded, making it easy to parse quickly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no annotations and no output schema, the description is incomplete. It doesn't explain what 'available spaces' means, what 'current context' includes, or what the return values look like. For a tool that likely returns a list of Kibana spaces, more context is needed to guide the agent effectively.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema description coverage is 100%, so the input schema already documents the 'include_details' parameter. The description doesn't add any parameter-specific information beyond what's in the schema, such as examples or edge cases, but the baseline is 3 when the schema does the heavy lifting.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Get' and the resource 'all available Kibana spaces with current context', making the purpose understandable. However, it doesn't explicitly differentiate this tool from its siblings like 'list_all_kibana_api_paths' or 'search_kibana_api_paths', which might also involve listing Kibana resources.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention any prerequisites, exclusions, or compare it to sibling tools like 'list_all_kibana_api_paths', leaving the agent to infer usage from the tool name alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_kibana_api_detailC

Get details for a specific Kibana API endpoint

ParametersJSON Schema
NameRequiredDescriptionDefault
methodYesHTTP method, e.g. GET, POST, PUT, DELETE
pathYesAPI path, e.g. /api/actions/connector_types

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It states what the tool does but doesn't describe how it behaves—such as whether it's read-only, what format the details are returned in, error handling, or any rate limits. This is a significant gap for a tool with no annotation coverage.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence that directly states the tool's purpose without any fluff. It's appropriately sized and front-loaded, making it easy to parse quickly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity of querying API endpoints and the lack of annotations and output schema, the description is insufficient. It doesn't explain what 'details' include, how results are structured, or any behavioral aspects like safety or performance, leaving the agent with incomplete information for proper use.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema description coverage is 100%, with both parameters ('method' and 'path') well-documented in the schema. The description adds no additional meaning beyond implying that these parameters identify a specific endpoint, which is already clear from the schema. This meets the baseline for high schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb ('Get details') and resource ('specific Kibana API endpoint'), making the purpose immediately understandable. However, it doesn't differentiate from sibling tools like 'list_all_kibana_api_paths' or 'search_kibana_api_paths' which also deal with Kibana API endpoints, so it doesn't fully distinguish itself from alternatives.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives like 'list_all_kibana_api_paths' or 'execute_kb_api'. It doesn't mention prerequisites, context, or exclusions, leaving the agent to infer usage based on the name alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_statusB

Get Kibana server status with multi-space support

ParametersJSON Schema
NameRequiredDescriptionDefault
spaceNoTarget Kibana space (optional, defaults to configured space)

TDQS

B3.1/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It states what the tool does but lacks behavioral details: it doesn't specify if this is a read-only operation, what permissions are required, whether it affects system state, rate limits, or what the output format looks like (e.g., JSON structure, error handling). For a tool with no annotation coverage, this is a significant gap in transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence that front-loads the core purpose ('Get Kibana server status') and adds a key feature ('with multi-space support'). There is no wasted verbiage, and it's appropriately sized for a simple tool with one optional parameter.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's low complexity (1 optional parameter, no output schema, no annotations), the description is minimally complete. It covers the basic purpose but lacks context on usage guidelines, behavioral traits, or output details. For a status-checking tool, it should ideally mention what 'status' entails (e.g., health metrics, version info) or how it differs from siblings, but it's adequate as a starting point.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, with the single parameter 'space' documented in the schema as optional and defaulting to configured space. The description adds minimal value beyond this by mentioning 'multi-space support', which implies the parameter's purpose but doesn't provide additional syntax or format details. Baseline 3 is appropriate as the schema handles parameter documentation adequately.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb ('Get') and resource ('Kibana server status'), making the purpose evident. It adds specificity with 'multi-space support' which distinguishes it from generic status tools. However, it doesn't explicitly differentiate from sibling tools like 'get_kibana_api_detail' or 'execute_kb_api', which might also retrieve status-related information.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It mentions 'multi-space support' but doesn't explain if this is for checking overall server health, space-specific status, or when to prefer it over siblings like 'get_available_spaces' or 'execute_kb_api'. No explicit when/when-not instructions or prerequisites are included.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_all_kibana_api_pathsB

List all Kibana API endpoints as a resource list

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

B3.2/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden for behavioral disclosure. It states what the tool does but doesn't describe important behavioral traits like whether this is a read-only operation, what format the resource list returns, whether there are rate limits, or if authentication is required. The description is functional but lacks operational context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence that communicates the core functionality without any wasted words. It's appropriately sized for a zero-parameter tool and front-loads the essential information ('List all Kibana API endpoints').

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter tool with no output schema, the description adequately states what the tool does but lacks important context about the return format, behavioral characteristics, and differentiation from sibling tools. Given the complexity of API endpoint listing and the absence of annotations/output schema, the description should provide more operational guidance to be truly complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has 0 parameters with 100% schema description coverage, so the baseline is 4. The description appropriately doesn't discuss parameters since none exist, and the schema fully documents this absence without needing additional explanation in the description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('List all') and resource ('Kibana API endpoints as a resource list'), making the purpose immediately understandable. However, it doesn't explicitly differentiate from sibling tools like 'search_kibana_api_paths' or 'get_kibana_api_detail', which would require more specific scope information.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives like 'search_kibana_api_paths' or 'get_kibana_api_detail'. There's no mention of use cases, prerequisites, or comparisons with sibling tools, leaving the agent without contextual usage information.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

search_kibana_api_pathsC

Search Kibana API endpoints by keyword

ParametersJSON Schema
NameRequiredDescriptionDefault
searchYesSearch keyword for filtering API endpoints

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool searches endpoints by keyword, but doesn't describe behavioral traits such as whether it's read-only, safe to use, what the output format looks like (e.g., list of paths, details), or any limitations (e.g., search scope, rate limits). For a tool with zero annotation coverage, this is a significant gap in transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence: 'Search Kibana API endpoints by keyword'. It's front-loaded with the core action and resource, with zero wasted words. Every part of the sentence earns its place by conveying essential purpose, making it highly concise and well-structured.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (a search function with one parameter) and the lack of annotations and output schema, the description is incomplete. It doesn't explain what the tool returns (e.g., a list of endpoint paths, details, or matches), how results are formatted, or any behavioral context needed for effective use. This leaves significant gaps for the agent to understand the tool's full context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% description coverage, with the single parameter 'search' documented as 'Search keyword for filtering API endpoints'. The description adds no additional meaning beyond this, as it only repeats the keyword concept without elaborating on syntax, format, or examples. Given the high schema coverage, the baseline score of 3 is appropriate, as the schema does the heavy lifting.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Search Kibana API endpoints by keyword'. It specifies the verb ('search'), resource ('Kibana API endpoints'), and mechanism ('by keyword'), which is specific and actionable. However, it doesn't explicitly differentiate from sibling tools like 'list_all_kibana_api_paths' or 'get_kibana_api_detail', which prevents a perfect score.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention sibling tools like 'list_all_kibana_api_paths' (which might list all endpoints without filtering) or 'get_kibana_api_detail' (which might retrieve details for a specific endpoint), leaving the agent to infer usage context. This lack of explicit when-to-use or alternative references results in minimal guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS

A3.5/5.0

Scored across 6 tools

Disambiguation5/5

Each tool has a clearly distinct purpose with no overlap: execute_kb_api performs custom API calls, get_available_spaces lists spaces, get_kibana_api_detail provides endpoint details, get_status checks server status, list_all_kibana_api_paths enumerates all endpoints, and search_kibana_api_paths searches endpoints. The descriptions reinforce these unique functions, making misselection unlikely.

Naming Consistency5/5

All tools follow a consistent verb_noun pattern with snake_case: execute_kb_api, get_available_spaces, get_kibana_api_detail, get_status, list_all_kibana_api_paths, and search_kibana_api_paths. The naming is predictable and readable throughout the set, with no deviations in style or convention.

Tool Count5/5

With 6 tools, the count is well-scoped for a Kibana MCP server focused on API exploration and execution. Each tool earns its place by covering distinct aspects like status, spaces, endpoint listing, searching, detailing, and execution, avoiding bloat while providing comprehensive functionality.

Completeness4/5

The tool set is highly complete for exploring and interacting with Kibana APIs, covering discovery (list/search), details, spaces, status, and execution. A minor gap exists in lacking direct CRUD operations for Kibana objects like dashboards or visualizations, but agents can work around this using execute_kb_api for custom requests.
