zendesk-mcp

A Model Context Protocol server that exposes Zendesk ticket read and write tools to Claude Code and other MCP clients.

What it does

• Search and fetch Zendesk tickets, comments, and attachments
• Post public replies and internal notes
• Set ticket status and assign tickets to agents
• Read and write time-tracking entries
• Format a ticket as a Markdown issue draft for handoff to a tracker (GitLab, GitHub, Jira)
• (Optional) Read linked GitLab issues / MRs / commits via the Git-Zen Zendesk app

Prerequisites

• Python 3.10 or newer
• A Zendesk OAuth client. A Zendesk admin can create one at: https://<your-subdomain>.zendesk.com/admin/apps-integrations/apis/zendesk-api/oauth_clients Set the redirect URL to http://localhost:8787/callback and request scopes read write.

Install

Install into a project-local virtualenv. Using a venv keeps zendesk-mcp and its dependencies isolated from your system Python and from other projects, and is the recommended path for everything below.

From a clone of this repository:

python3 -m venv .venv
.venv/bin/pip install --upgrade pip
.venv/bin/pip install -e .

For development (also installs pytest):

.venv/bin/pip install -e ".[dev]"

Throughout this README, commands use the venv's binaries via .venv/bin/.... You can instead source .venv/bin/activate once per shell and drop the prefix — the result is the same.

OAuth setup

Run the interactive setup using the venv's Python:

.venv/bin/python -m zendesk_mcp setup

You will be prompted for:

1. Your Zendesk subdomain (e.g. acme for acme.zendesk.com)
2. The OAuth client ID created by your admin
3. The OAuth client secret
4. (Optional) A Git-Zen integration field ID — see Optional: Git-Zen integration

The setup opens a browser for the OAuth authorization step, then writes a token to ~/.config/zendesk-mcp/config.json (mode 0600).

If you have no browser, the URL is printed to the terminal — open it on any device, click Allow, and paste the resulting redirect URL back into the prompt.

Register with Claude Code

Register the MCP server using the venv's Python by absolute path. Claude Code launches the server in a fresh shell that does not inherit your activated venv, so the absolute path is required — pointing at a bare python here will fail to import zendesk_mcp.

ZENDESK_MCP_DIR="$(pwd)"   # run this from the repo root, after install
claude mcp add --scope user zendesk -- "$ZENDESK_MCP_DIR/.venv/bin/python" -m zendesk_mcp

Or just inline the absolute path you want:

claude mcp add --scope user zendesk -- /absolute/path/to/zendesk-mcp/.venv/bin/python -m zendesk_mcp

Then add the read tools to permissions.allow in ~/.claude/settings.json to avoid per-call prompts:

{
  "permissions": {
    "allow": [
      "mcp__zendesk__zendesk_get_ticket",
      "mcp__zendesk__zendesk_get_comments",
      "mcp__zendesk__zendesk_list_attachments",
      "mcp__zendesk__zendesk_download_attachment",
      "mcp__zendesk__zendesk_search_tickets",
      "mcp__zendesk__zendesk_ticket_to_gitlab_context"
    ]
  }
}

Write tools (zendesk_post_comment, zendesk_post_internal_note, zendesk_set_ticket_status, zendesk_assign_ticket, zendesk_log_time) are intentionally not in the default allow-list — Claude will prompt you per call.

Tools

Optional: Git-Zen integration

If your Zendesk instance uses the Git-Zen app, the zendesk_get_git_zen_links tool can read its custom-field payload. Find your instance's Git-Zen custom field ID under Admin → Tickets → Fields (it is a numeric ID), then either set it during .venv/bin/python -m zendesk_mcp setup or edit ~/.config/zendesk-mcp/config.json to add:

{
  "git_zen_field_id": 12345678901234
}

Without this configured, zendesk_get_git_zen_links returns a "not configured" message.

Development

python3 -m venv .venv
.venv/bin/pip install -e ".[dev]"
.venv/bin/pytest

Tests run on Python 3.10, 3.11, and 3.12 in CI (see .github/workflows/test.yml).
