ITSM MCP Server tools reference

Reference for all tools available in the ITSM MCP Server, organized by functional area: incident management, change management, and employee experience.

Warning:

• Only the tools listed here are available. If any other tools display in the Tools definition, you must review and resolve the skipped records for those tools. For information on reviewing and resolving skipped records, see Review skipped records using related lists.

• You need the sn_mcp_server.viewer role as the base role to access ITSM MCP server tools. For more information, see Configure an MCP client to connect to an MCP server.

Incident management tools

The following tools are available for incident management in the ITSM MCP Server.

<table id=“table-incident-management-tools”><thead><tr><th>

Tool name

</th><th>

Description

</th></tr></thead><tbody><tr><td>

sn_itsm_mcp_server.incident.get_details

</td><td>

Returns incident fields for a given incident number. The response is role-aware: fulfillers (itil or sn_incident_read) receive the full record, including assignment, CI, and work notes. Requesters receive a reduced, customer-safe field set and comments-only activity for incidents they own, and a 404 response for incidents they don’t own.

</td></tr><tr><td>

sn_itsm_mcp_server.incident.modify

</td><td>

Updates fields on an incident, including work notes, comments, assignee, and assignment group. Updates run through platform-native APIs with full business rule execution.

The tool is role-aware. Fulfillers (itil or sn_incident_write) can set any modifiable field with no ownership restriction. Requesters can perform only the following actions, and only on an incident they own: add a customer-visible comment, escalate the incident using the escalate and escalation_reason inputs (submitted as a standalone operation), or mark an active incident Resolved. A requester attempting any other field update receives a 403; a non-owned incident returns 404.

</td></tr><tr><td>

sn_itsm_mcp_server.incident.search_similar

</td><td>

Searches for incidents similar to a given incident or natural language description using semantic search and returns ranked results.

</td></tr><tr><td>

sn_itsm_mcp_server.lookup_assignment_groups

</td><td>

Looks up available assignment groups and individual assignees.

</td></tr><tr><td>

sn_itsm_mcp_server.lookup_users

</td><td>

Searches similar Knowledge Base (KB) articles based on the input query or details, to find existing content that has already documented the issue or its resolution.

</td></tr><tr><td>

sn_itsm_mcp_server .incident.get_kb_details

</td><td>

Retrieves details for a single published KB article using number or sys_id, that includes title, knowledge base, state, publish date, and full body text.

The following tools are available for employees and requesters to manage their own tickets in the ITSM MCP Server. These tools apply only to tickets where the authenticated user is the caller or requester.

Description

</th></tr></thead><tbody><tr><td>

sn_itsm_mcp_server.requester.create_incident

</td><td>

Guides a requester through a multi-step workflow to create a new incident or request a catalog item. The workflow includes knowledge base deflection (searches for self-service articles), catalog item redirection (searches for matching service catalog items), duplicate detection (identifies similar open incidents by the requester), and incident creation with field review. Returns an incident number with portal link or a request item number depending on the path taken.Note: This tool uses the Create incident AI agent as an MCP tool. To configure, see Configure an AI agent as an MCP tool.

</td></tr><tr><td>

sn_itsm_mcp_server.requester.check_status
