Zabbix MCP Server

connector_get

Read-only

Retrieve and filter Zabbix event connectors to inspect endpoints, formats, authentication, and forwarding rules for SIEM, alerting, or custom event pipelines.

Instructions

Retrieve event connectors. Connectors stream Zabbix events to external systems in real time, enabling SIEM integration, custom event pipelines, and third-party alerting. Each connector defines a URL endpoint, data format, authentication, and filtering rules for which events to forward.

Input Schema

NameRequiredDescriptionDefault
limitNoMaximum number of results to return.
filterNoReturn only results whose properties exactly match the given values (a single value or a list of values per key). Example: {"status": 0} or {"status": [0, 1]}. Keys: attempt_interval (7.0+), authtype, connectorid, data_type, http_proxy, item_value_type (7.0+), max_attempts, max_records, max_senders, name, password, protocol, ssl_cert_file, ssl_key_file, ssl_key_password, status, tags_evaltype, timeout, token, url, username, verify_host, verify_peer. Text properties cannot be filtered; use 'search' for them.
outputNoProperties of the connector object to return. Pass 'extend' for all, 'count' for the number of matches only, or a list of property names. Default when omitted: connectorid, name, status. Properties: attempt_interval (7.0+), authtype, connectorid, data_type, description, http_proxy, item_value_type (7.0+), max_attempts, max_records, max_senders, name, password, protocol, ssl_cert_file, ssl_key_file, ssl_key_password, status, tags_evaltype, timeout, token, url, username, verify_host, verify_peer.
searchNoReturn results whose string properties contain the given pattern (case-insensitive; '*' is a wildcard when searchWildcardsEnabled is true). Example: {"name": "web"}. Keys: attempt_interval (7.0+), description, http_proxy, name, password, ssl_cert_file, ssl_key_file, ssl_key_password, timeout, token, url, username.
serverNoTarget Zabbix server. Available: default. Defaults to 'default' if omitted.
raw_jsonNoStrips the security disclaimer preamble from the response so it is pure JSON. Default: false. Requires the bearer token to have 'allow_raw_json' explicitly enabled by an operator in the admin portal - tokens without that policy receive a PolicyError instead. WARNING: setting true bypasses the prompt-injection mitigation marker that wraps untrusted Zabbix data (host names, item descriptions, problem text). LLM clients (Claude, GPT, Cursor, ...) should leave this false; only programmatic non-LLM consumers (Python scripts, n8n workflows that json.loads the result) should set true.
sortfieldNoSort by one or more of: connectorid, name, data_type, status (a list for several; pair with 'sortorder'). No other property is sortable.
sortorderNoSort order: 'ASC' (ascending) or 'DESC' (descending).
countOutputNoReturn the count of matching results instead of the actual data.
searchByAnyNoIf true, return results matching ANY search field (OR). Default is ALL fields (AND).
connectoridsNoReturn only connectors with the given IDs.
extra_paramsNoOther native connector.get parameters, merged into the request as-is. Sub-object selects (value 'extend', 'count' or a list of property names): selectTags. Any other key is refused here, because Zabbix would silently ignore it. For a parameter you are sure exists on your release but is not listed, use zabbix_raw_api_call.
searchWildcardsEnabledNoIf true, enable * and ? wildcards in search patterns.

  2. First observedv1.41.0

TDQS

B3.1/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds genuinely useful domain context about what connectors do and what they contain, but omits two operational facts an agent would want: that the returned objects include secret fields (password, token, ssl_key_password), and that results are paginated via limit.

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

Conciseness3/5

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

The verb+resource is front-loaded, which is good, but of the three sentences only the first aids invocation. The SIEM/pipeline/alerting sentence is marketing-flavored background that an agent already infers from the connector definition sentence.

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 13-parameter but fully documented, all-optional, read-only listing tool, the description is adequate on its own. However, with no output schema present, the description should at least mention that secret properties can be selected via output, since that is a real footgun the schema only quietly allows.

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% and the parameter docs are unusually detailed (filter vs. search key lists, output defaults, sort field restrictions, raw_json policy). The description adds nothing beyond the schema, so the baseline 3 applies.

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?

"Retrieve event connectors" gives a specific verb plus resource, and the follow-up sentences define what a connector is (URL endpoint, data format, auth, filtering rules), so the object is unambiguous. It stops short of distinguishing this from siblings such as event_get or configuration_export, which an agent must infer.

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?

There is no when-to-use or when-not-to-use guidance, and no alternative named. The description explains the domain concept but never says under what circumstances an agent should call connector_get rather than event_get, action_get, or mediatype_get.

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