MCP Taiga

Taiga MCP server

A TypeScript MCP server for Taiga. It gives LLM clients six tools for projects, work items, sprints, comments, attachments, and wiki pages.

The server uses MCP revision 2026-07-28, native fetch, and either stdio or streamable HTTP.

Requirements

• Node.js 24 or newer.
• A Taiga account on taiga.io or a self-hosted instance.
• TAIGA_USERNAME and TAIGA_PASSWORD.

Set TAIGA_API_URL for a self-hosted instance. Include /api/v1 in the URL.

Install

Published package

Use the published package from an MCP client that accepts a stdio command:

{
  "mcpServers": {
    "taiga": {
      "command": "npx",
      "args": ["-y", "mcp-taiga"],
      "env": {
        "TAIGA_USERNAME": "your_username",
        "TAIGA_PASSWORD": "your_password"
      }
    }
  }
}

Pass credentials through the client environment. An npx install does not load a repository .env file.

Local checkout

git clone https://github.com/negoro26/mcp-taiga.git
cd mcp-taiga
npm ci
npm run build
cp .env.example .env

Fill in .env, then configure the client to run:

{
  "mcpServers": {
    "taiga": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-taiga/dist/src/index.js"],
      "cwd": "/absolute/path/to/mcp-taiga"
    }
  }
}

A local checkout loads .env with Node's built-in environment loader. Do not commit .env.

Oh My Pi

Start OMP in the checkout and run:

/mcp add

Choose a local stdio server, then use:

command: node
args: /absolute/path/to/mcp-taiga/dist/src/index.js
cwd: /absolute/path/to/mcp-taiga

Run /mcp test taiga or /mcp list to verify the server. OMP configuration lives in ~/.omp/agent/mcp.json.

HTTP transport

Set TAIGA_HTTP_PORT to serve the same tools over streamable HTTP:

TAIGA_HTTP_PORT=3000 npx -y mcp-taiga

The endpoint is:

http://127.0.0.1:3000/mcp

Configure URL-based clients with:

{
  "mcpServers": {
    "taiga": {
      "type": "http",
      "url": "http://127.0.0.1:3000/mcp"
    }
  }
}

The HTTP server is stateless, validates the Host and Origin headers, and defaults to loopback. A routable bind address prints a warning because the connection is not encrypted.

Tools

The server exposes six tools and 28 operation pairs.

Input conventions

• Projects accept a numeric ID or slug.
• Work items accept a numeric ID or a #reference. A reference also needs project.
• Members accept an ID, username, full name, or me.
• Statuses, priorities, severities, issue types, and sprint names resolve to Taiga IDs.
• Batch work-item creation accepts at most 20 items.
• attachments.download returns metadata by default. Set includeContent: true to return bytes, or set savePath to write them locally.
• Listings return dense plain text. Empty lists are successful results.

Safety and reliability

• 401 responses trigger one token refresh and retry.
• 429 responses retry at most twice and honor Retry-After. Waits longer than five seconds fail with a retry message.
• 5xx responses are not retried because a write may already have succeeded.
• Project, user, and taxonomy metadata is cached for 60 seconds.
• Requests time out after 30 seconds.
• Attachment downloads reject redirects, cap reads at 10 MB, require the Taiga hostname, and do not send the bearer token to media hosts.
• File downloads refuse to overwrite an existing file.
• Deletes accept one target at a time. Batch creation does not imply batch deletion.

Docker

docker build -t mcp-taiga .
docker run --rm -i --env-file .env mcp-taiga

For HTTP mode:

docker run --rm -p 127.0.0.1:3000:3000 \
  -e TAIGA_HTTP_PORT=3000 \
  --env-file .env \
  mcp-taiga

The container uses Node.js 24 Alpine and runs as the non-root node user.

Development

npm ci
npm run check
npm run lint
npm test

The test suite covers pure helpers, the MCP stdio handshake, all tool operations against a mock Taiga server, streamable HTTP, and live Taiga reads.
