Freshdesk MCP Server

An MCP server for the Freshdesk API v2. It lets an AI agent search and read tickets and their conversations, contacts, companies, agents, groups, the knowledge base (solutions), SLA policies, business hours and canned responses and, on explicit request, create and update records, reply to tickets, add notes and (with confirmation) delete, merge or convert records.

• Transport: MCP Streamable HTTP at POST /mcp, health probe at GET /health

• Stateless and multi-tenant: credentials arrive on every request as HTTP headers and are never stored; every tool is listed from the first tools/list

• Python 3.12, uv, FastMCP, httpx

• License: Apache-2.0, Copyright 2026 MSPbots.ai

Authentication headers

Where to get them: the subdomain is the acme in https://acme.freshdesk.com. The API key is under Profile settings -> View API Key of the agent whose permissions the agent should have; every action is performed, and audited, as that agent.

How the key is sent to Freshdesk: every call goes to https://{subdomain}.freshdesk.com/api/v2/... with HTTP Basic authentication (the API key as user name, X as password). Only freshdesk.com accounts are accepted, so the key is never sent to another host.

A request to /mcp without both headers gets HTTP 401 naming the missing one; a domain that is not a Freshdesk account gets HTTP 400.

Tools

All tools return a JSON string. List tools take page and perPage (max 100) and return {count, page, has_more, next_page}; search tools return 30 results per page for at most 10 pages. Ticket status: 2 Open, 3 Pending, 4 Resolved, 5 Closed; priority: 1 Low, 2 Medium, 3 High, 4 Urgent. write marks tools that change data; confirm marks tools that also need confirm: true.

Errors come back as a JSON envelope instead of an exception:

{"error": {"code": "invalid_argument", "message": "Freshdesk returned HTTP 400 for contacts: Validation failed - email: It should be a valid email address", "retryable": false}}

code is one of not_configured, unauthorized, not_found, invalid_argument, rate_limited, upstream_error; Freshdesk's per-field validation messages are kept. Reads are retried with backoff on 429, 5xx and network errors; writes only on 429 (honouring Retry-After). Freshdesk limits API calls per minute according to the plan.

Run locally

uv sync
uv run python -m freshdesk_mcp          # listens on 0.0.0.0:8080

or with Docker:

docker build --platform linux/amd64 -t freshdesk-mcp:dev .
docker run --rm -p 8080:8080 freshdesk-mcp:dev

Configuration (environment variables, all optional): MCP_HTTP_HOST (default 0.0.0.0), MCP_HTTP_PORT (default 8080), LOG_LEVEL (default INFO). Credentials are never read from the environment.

Testing example

# list tools
curl -s http://localhost:8080/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "X-Freshdesk-Domain: acme" \
  -H "X-Freshdesk-Api-Key: your-freshdesk-api-key" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'

# open urgent tickets
curl -s http://localhost:8080/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "X-Freshdesk-Domain: acme" \
  -H "X-Freshdesk-Api-Key: your-freshdesk-api-key" \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"freshdesk_tickets_search","arguments":{"query":"status:2 AND priority:4"}}}'

Unit tests (no network access needed):

uv run pytest

Delivery notes

• Tool count (66). Kept as is because the tool names are an existing contract; every tool is listed from the first tools/list.

• Confirmation for irreversible actions. Older versions asked the user to confirm deletes mid-call and carried on when the client could not show the prompt, which is always the case behind a stateless gateway. The 12 delete / merge / make-agent tools now need confirm: true and otherwise return a "not done" result describing the action.

• Fixes against the Freshdesk API reference. freshdesk_contacts_send_invite now uses PUT (the documented method); freshdesk_agents_create sends the agent type as Freshdesk's numeric agent_type (support_agent 1, field_agent 2, collaborator 3) instead of an unknown type field.

• Search. Queries are wrapped in the double quotes Freshdesk requires; string values inside take single quotes (tag:'vip').

• Notes default to private; replies email the requester, which the description states.
