trac-mcp-server

Standalone MCP server that gives AI agents full access to Trac project management -- tickets, wiki, milestones, and search -- via the Model Context Protocol.

Quick Start

Requires Python 3.10 or later.

pip install .

Set your Trac connection:

export TRAC_URL="https://trac.example.com"
export TRAC_USERNAME="your-username"
export TRAC_PASSWORD="your-password"

Run the server:

trac-mcp-server

Using auto-pm? When trac-mcp-server is driven through auto-pm, auto-pm reads its connection settings from .auto_pm/config.yml in your project root (rather than the environment variables above). Run auto-pm setup in your project directory to generate the file; the resulting .auto_pm/config.yml carries trac.url, trac.username, a ${TRAC_PASSWORD} reference, and component mappings.

Configuration

Configuration via environment variables, .env file, or YAML config file (.trac_mcp/config.yaml):

Variable	Required	Default	Description
TRAC_URL	Yes	--	Trac instance URL
TRAC_USERNAME	Yes	--	Trac username
TRAC_PASSWORD	Yes	--	Trac password
TRAC_INSECURE	No	false	Skip SSL verification (development only)
TRAC_DEBUG	No	false	Enable debug logging
TRAC_MAX_PARALLEL_REQUESTS	No	5	Max parallel XML-RPC requests
TRAC_MAX_BATCH_SIZE	No	500	Max items per batch operation (1-10000)
TRAC_RPC_TIMEOUT	No	60	Read timeout in seconds for XML-RPC requests (5-300)
TRAC_ALLOWED_INSTANCES	No	--	Comma-separated instances (/path on the TRAC_URL host, or absolute URL) the default identity may reach; unset = unrestricted. TRAC_URL must be on the list (ticket #110)
TRAC_MCP_TRANSPORT	No	stdio	MCP transport: stdio or http
TRAC_MCP_HOST	No	127.0.0.1	Bind host for the http transport
TRAC_MCP_PORT	No	8080	Bind port for the http transport
TRAC_MCP_AUTH_TOKEN	No	--	Bearer token required by the http transport
TRAC_IDENTITIES	No	--	Path to a file mapping per-caller bearer tokens to their own Trac username/password (http transport only)

For YAML config file format and advanced options, see Configuration Reference. For the http transport specifically, including multi-identity auth, see HTTP Transport.

MCP Client Integration

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "trac": {
      "command": "trac-mcp-server",
      "env": {
        "TRAC_URL": "https://trac.example.com",
        "TRAC_USERNAME": "your-username",
        "TRAC_PASSWORD": "your-password"
      }
    }
  }
}

Claude Code

claude mcp add trac -e TRAC_URL=https://trac.example.com \
  -e TRAC_USERNAME=your-username \
  -e TRAC_PASSWORD=your-password \
  -- trac-mcp-server

Other MCP Clients

Any MCP client that supports stdio transport can launch trac-mcp-server as a subprocess. Pass Trac credentials via environment variables.

For a shared or remote deployment, trac-mcp-server can also serve MCP over streamable HTTP instead of stdio:

TRAC_MCP_AUTH_TOKEN=your-token trac-mcp-server --transport http --port 8080

See HTTP Transport for auth, bind-safety rules, and reverse-proxy guidance.

Format Conversion CLI

The package also installs trac-convert, a standalone CLI for converting between TracWiki and Markdown without requiring a Trac connection. Useful for one-off conversions, editor pipelines, and clipboard workflows.

# Convert Markdown to TracWiki (stdin → stdout)
trac-convert --from md --to tracwiki < README.md > README.tw

# Convert a file (auto-detects source format)
trac-convert --to md notes.tw -o notes.md

# Clipboard round-trip
trac-convert --from-clipboard --to tracwiki --to-clipboard

Supports stdin/stdout pipes, file I/O, and system clipboard on Linux, macOS, and Windows (via pyperclip). See CLI Reference for the full flag list.

Trac Wiki I/O

trac-convert can also read from and write to a live Trac instance via --from-wiki PAGE and --to-wiki PAGE, reusing the same credentials and config precedence as trac-mcp-server: .trac_mcp/config.yml, TRAC_* env vars, or --trac-* CLI flags — CLI wins.

# Verify Trac connectivity (prints resolved config, pings server)
trac-convert --check-trac

# Fetch a Trac wiki page, convert to Markdown, save locally
trac-convert --from-wiki DesignDoc --to md -o design.md

# Edit design.md in your favourite editor, then push it back
trac-convert --from-file design.md --to-wiki DesignDoc --wiki-comment "Refined via CLI"

# One-liner Trac → clipboard for quick reference lookup
trac-convert --from-wiki ReleaseNotes --to md --to-clipboard

Auth setup: use an existing .trac_mcp/config.yml (the same file trac-mcp-server uses) or supply ad-hoc flags — --trac-url, --trac-username, --trac-password-file ~/.trac_pass (prefer --trac-password-file to keep secrets out of shell history). See Configuration for the full precedence rules.

Trac errors (auth, network, page-not-found, permission-denied) exit with code 4 and write a human-readable message to stderr. See CLI Reference for the full flag list.

File Transfer CLI

When the server runs on another machine (the HTTP transport), its file tools cannot see your files, and over HTTP they refuse server-side paths by default. trac-mcp runs on your machine and moves the bytes through the server for you, keeping your identity and the server's conversion and link checks:

trac-mcp wiki-push Docs/Design design.md          # Markdown is converted on the way in
trac-mcp wiki-pull Docs/Design design.md
trac-mcp attach-put --ticket 42 trace.bin
trac-mcp attach-get --page Docs/Design diagram.png diagram.png

It connects with the nearest .mcp.json entry (or --url). See CLI Reference and File Access.

Development

pip install -e ".[dev]"
pytest tests/ -v

The two CI halves

./ci.sh        # lint + offline tests + dual-binary build. Hermetic:
               # no credentials, no daemon, no network
./ci-live.sh   # the same suite with --run-live, against a real Trac

ci.sh is what GitHub Actions runs, and it deliberately does not pass --run-live, so every @pytest.mark.live test is skipped there. Those tests are the only place this project exercises the real Trac substrate, so run ci-live.sh too before deploying a change to a shared daemon. It needs TRAC_URL, TRAC_USERNAME and TRAC_PASSWORD (see .env.example), and without them it exits non-zero without running pytest — not run must not be able to look like passed.

ci.sh runs the offline suite with TRAC_* scrubbed from the environment, and .env is loaded only under --run-live. An offline test that needs credentials therefore fails locally rather than only on Actions.
