Zabbix MCP Server

hostinterface_get

Read-only

Retrieve host interfaces (agent, SNMP, JMX, IPMI) to see how Zabbix connects to hosts for data collection. Filter by host, interface ID, IP, or type.

Instructions

Retrieve host interfaces. Each host can have multiple interfaces (agent, SNMP, JMX, IPMI) that define how Zabbix connects to the host for data collection. Items are bound to specific interfaces.

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: available (6.0+), disable_until (6.0+), dns, error (6.0+), errors_from (6.0+), hostid, interfaceid, ip, main, port, type, useip. Text properties cannot be filtered; use 'search' for them.
outputNoProperties of the hostinterface object to return. Pass 'extend' for all, 'count' for the number of matches only, or a list of property names. Default when omitted: interfaceid, hostid, type, ip, port, main. Properties: available (6.0+), details, disable_until (6.0+), dns, error (6.0+), errors_from (6.0+), hostid, interfaceid, ip, main, port, type, useip.
searchNoReturn results whose string properties contain the given pattern (case-insensitive; '*' is a wildcard when searchWildcardsEnabled is true). Example: {"name": "web"}. Keys: dns, error (6.0+), ip, port.
serverNoTarget Zabbix server. Available: default. Defaults to 'default' if omitted.
hostidsNoReturn only interfaces that belong to the given hosts.
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: interfaceid, dns, ip (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 hostinterface.get parameters, merged into the request as-is. Parameters: groupCount, itemids, limitSelects, triggerids. 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): selectHosts, selectItems. 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.
interfaceidsNoReturn only interfaces with the given IDs.
searchWildcardsEnabledNoIf true, enable * and ? wildcards in search patterns.

  2. First observedv1.41.0

TDQS

B3.3/5.0
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 description need not restate safety. It adds domain context about multiple interfaces and item binding but no behavioral details such as permission requirements, pagination, or result shape beyond the resource model.

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?

Two sentences, front-loaded with the action and with no filler. The second sentence earns its place by defining what a host interface is and why multiple can exist.

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 14-parameter read tool with no output schema, the description is thin: it defines the resource but not the return shape, filtering approach, or how to choose among the many optional arguments. The rich schema and annotations compensate enough to keep it at minimum viable.

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, so the baseline is 3. The description adds no parameter-level meaning; it does not explain filter/search interplay or output options, but the schema already does.

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 specific verb+resource ('Retrieve host interfaces') and clarifies the object by naming interface types (agent, SNMP, JMX, IPMI) and their relationship to items. It does not explicitly differentiate from siblings such as host_get or item_get, so it is clear but not sibling-routing.

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?

No when-to-use or when-not-to-use guidance is given; it never says to prefer host_get for host records or item_get for items. The only implied usage is that this is the read path for host-interface records, leaving the agent to infer alternatives.

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