Zabbix MCP Server

mediatype_get

Read-only

Retrieves notification media types configured in Zabbix to list delivery channels such as email, SMS, and webhooks, helping diagnose notification configuration and delivery issues.

Instructions

Retrieve notification media types configured in Zabbix. Media types define how notifications are delivered: Email, SMS, webhook (Slack, PagerDuty, Teams, etc.), or custom scripts. Each media type has its own set of parameters such as SMTP settings, webhook URL, or script path. Use this to list available notification channels or diagnose delivery configuration.

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: access_expires_in (7.4+), access_token (7.4+), access_token_updated (7.4+), attempt_interval, authorization_url (7.4+), client_id (7.4+), client_secret (7.4+), event_menu_name, event_menu_url, exec_params (removed in 6.4), exec_path, gsm_modem, maxattempts, maxsessions, mediatypeid, message_format (7.0+), name, passwd, process_tags, provider (6.4+), redirection_url (7.4+), refresh_token (7.4+), show_event_menu, smtp_authentication, smtp_email, smtp_helo, smtp_port, smtp_security, smtp_server, smtp_verify_host, smtp_verify_peer, status, timeout, token_url (7.4+), tokens_status (7.4+), type, username. Text properties cannot be filtered; use 'search' for them.
outputNoProperties of the mediatype object to return. Pass 'extend' for all, 'count' for the number of matches only, or a list of property names. Default when omitted: mediatypeid, name, type, status. Properties: access_expires_in (7.4+), access_token (7.4+), access_token_updated (7.4+), attempt_interval, authorization_url (7.4+), client_id (7.4+), client_secret (7.4+), content_type (removed in 7.2), description, event_menu_name, event_menu_url, exec_params (removed in 6.4), exec_path, gsm_modem, maxattempts, maxsessions, mediatypeid, message_format (7.0+), name, parameters, passwd, process_tags, provider (6.4+), redirection_url (7.4+), refresh_token (7.4+), script, show_event_menu, smtp_authentication, smtp_email, smtp_helo, smtp_port, smtp_security, smtp_server, smtp_verify_host, smtp_verify_peer, status, timeout, token_url (7.4+), tokens_status (7.4+), type, username.
searchNoReturn results whose string properties contain the given pattern (case-insensitive; '*' is a wildcard when searchWildcardsEnabled is true). Example: {"name": "web"}. Keys: access_token (7.4+), attempt_interval, authorization_url (7.4+), client_id (7.4+), client_secret (7.4+), description, event_menu_name, event_menu_url, exec_params (removed in 6.4), exec_path, gsm_modem, name, passwd, redirection_url (7.4+), refresh_token (7.4+), script, smtp_email, smtp_helo, smtp_server, timeout, token_url (7.4+), 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: mediatypeid (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).
extra_paramsNoOther native mediatype.get parameters, merged into the request as-is. Parameters: groupCount, mediaids, userids. Switches (true turns one on, false is the same as leaving it out): groupCount. groupCount goes with output='count': the count is then split by the ID filters the method groups by (hostids, groupids ...), one row per ID with 'rowscount'; a single row without such a filter. Sub-object selects (value 'extend', 'count' or a list of property names): selectActions (7.0+), selectMessageTemplates, selectUsers. 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.
mediatypeidsNoReturn only media types with the given IDs.
searchWildcardsEnabledNoIf true, enable * and ? wildcards in search patterns.

  2. First observedv1.41.0

TDQS

A3.6/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true and openWorldHint=false. The description adds domain context about what media types contain, but says nothing about response shape, pagination, or the security preamble behavior covered by the raw_json parameter in the schema. With annotations covering safety, a 3 is appropriate.

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?

Three sentences: the first states the operation, the next two explain the resource. It is front-loaded and free of filler, though slightly longer than a strictly minimal definition.

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?

For a read-only list tool with 13 optional parameters and no output schema, the description adequately explains what is returned and when to use it. The schema carries the detailed parameter and filtering behavior, so little is missing.

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%, so every parameter is already documented in the schema. The description mentions 'parameters such as SMTP settings, webhook URL, or script path' but this refers to returned object properties, not input parameters, and adds no 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 states a specific verb ('Retrieve') and resource ('notification media types configured in Zabbix'), then explains what those are. It does not explicitly differentiate from any sibling tool, but no sibling is close enough to cause confusion.

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

Usage Guidelines4/5

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

It gives clear contexts for use: 'list available notification channels or diagnose delivery configuration.' No when-not-to-use conditions or alternative tools are named, so it falls short of a 5.

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