Zabbix MCP Server

sla_get

Read-onlyIdempotent

Retrieve service level agreements (SLAs) from Zabbix to track uptime compliance and availability targets. Filter by SLA or service IDs, search, and paginate results.

Instructions

Get SLAs from Zabbix.

Service Level Agreements (SLAs) define uptime and availability targets for services. They track compliance with service objectives and generate reports on availability.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
limitNoMaximum number of results to return. Default is 100.
offsetNoNumber of matching records to skip. Use with 'limit' to page through results; check 'has_more' and 'total' in the response.
outputNoextend
searchNoDictionary with search criteria like {'name': 'Website'}.
slaidsNoList of SLA IDs to get. If empty, returns all SLAs.
sortfieldNoField to sort by. A deterministic sort is required for paging to be consistent.slaid
sortorderNoSort direction - 'ASC' or 'DESC'.ASC
serviceidsNoList of service IDs to get SLAs for.
count_outputNoIf true, returns only the count of matched objects as an integer.
filter_paramsNoAdditional filter parameters for advanced filtering.

TDQS

A3.5/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds domain context about SLAs but does not disclose operational behavior such as pagination or default result scope; it is not contradictory.

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

Conciseness4/5

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

The description is short and front-loaded with the actionable statement, followed by a brief, relevant explanation of what SLAs are. It stays within three sentences and avoids redundant restatement of the schema.

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

Completeness4/5

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

Given the rich optional-parameter schema, output schema, and safety annotations, the description is adequate for selecting and invoking this tool. It could add explicit mention of default 'all SLAs' behavior, but the schema already communicates that through slaids and limit defaults.

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?

With roughly 90% schema description coverage and detailed parameter descriptions for limit, offset, search, slaids, serviceids, and count_output, the schema already carries the parameter semantics. The description adds no parameter-specific meaning beyond the schema.

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 opens with a clear verb and resource: 'Get SLAs from Zabbix,' so an agent can immediately identify the operation. It does not explicitly contrast with related siblings such as service_get, but the SLA resource is distinct enough that the purpose is unambiguous.

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

Usage Guidelines3/5

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

The description implies this tool is for retrieving SLA definitions when SLA data is needed, but it provides no explicit when-to-use or when-not-to-use guidance. It does not name alternatives or exclusions, leaving usage boundaries to inference.

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