Zabbix MCP Server

usergroup_get

Read-only

Retrieve user groups to assign Zabbix permissions. Include host group rights, members, or tag filters for access control.

Instructions

Retrieve user groups. User groups are the primary mechanism for assigning permissions in Zabbix -- each group has a set of host group permissions (read, read-write, deny) and frontend/API access settings. Use selectRights to see the permission mappings, selectUsers to include group members, and selectTagFilters for tag-based permissions.

Input Schema

TableJSON 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: debug_mode, gui_access, mfa_status (7.0+), mfaid (7.0+), name, proxy_group_mode (8.0+), proxy_mode (8.0+), userdirectoryid (6.2+), users_status, usrgrpid. Text properties cannot be filtered; use 'search' for them.
outputNoProperties of the usergroup object to return. Pass 'extend' for all, 'count' for the number of matches only, or a comma-separated list of property names. Default when omitted: usrgrpid, name. Properties: debug_mode, gui_access, mfa_status (7.0+), mfaid (7.0+), name, proxy_group_mode (8.0+), proxy_mode (8.0+), userdirectoryid (6.2+), users_status, usrgrpid.
searchNoReturn results whose string properties contain the given pattern (case-insensitive; '*' is a wildcard when searchWildcardsEnabled is true). Example: {"name": "web"}. Keys: name.
serverNoTarget Zabbix server. Available: default. Defaults to 'default' if omitted.
useridsNoReturn only user groups that contain the given user IDs.
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: usrgrpid, name (comma-separated for several; pair with 'sortorder'). No other property is sortable.
sortorderNoSort order: 'ASC' (ascending) or 'DESC' (descending).
usrgrpidsNoReturn only user groups with the given IDs.
with_usersNoReturn only user groups that have at least one user.
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 usergroup.get parameters, merged into the request as-is. Parameters: limitSelects, mfa_status (7.0+), mfaids (7.0+), proxy_groupids (8.0+), proxyids (8.0+), status. Sub-object selects (value 'extend', 'count' or a list of property names): selectHostGroupRights (6.2+), selectProxies (8.0+), selectProxyGroups (8.0+), selectRights (removed in 7.2), selectTagFilters, selectTemplateGroupRights (6.2+), 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.
searchWildcardsEnabledNoIf true, enable * and ? wildcards in search patterns.

TDQS

A3.7/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds real domain semantics beyond the annotations: what a user group contains (host group permissions of read/read-write/deny, plus frontend/API access settings), which helps the agent interpret results. It stops short of noting that selectRights is removed in 7.2 (only visible in the schema), so not a full 5.

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?

Front-loaded with purpose in the first two words, then domain context, then the expansion pointers. Three tight sentences with essentially no filler, though the selectRights/selectUsers/selectTagFilters sentence is a partial restatement of schema content.

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 an output schema exists and all 15 parameters carry 100% schema descriptions, the description need not explain return values or param syntax. It supplies the missing conceptual layer — what a user group is and why the select expansions matter — which is enough to call the tool correctly; only the version-specific caveats on selectRights are absent.

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, and the baseline is 3. The description only name-drops three select sub-objects (which actually live inside extra_params) without adding syntax or format detail, so it adds marginal value over 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?

States a specific verb and resource ('Retrieve user groups') and immediately grounds it in the Zabbix domain ('primary mechanism for assigning permissions'), so the agent knows exactly what object it is fetching. It does not explicitly distinguish itself from the many sibling *_get tools (e.g., user_get, role_get), but the resource is unambiguous from the name and opening sentence.

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?

It tells the agent which select parameters to use for which purpose (selectRights for permission mappings, selectUsers for members, selectTagFilters for tag permissions), which is genuinely useful routing. However, it never states when to use usergroup_get versus alternatives like user_get or role_get, nor any prerequisite or exclusion, so usage is only implied.

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