Transkribus MCP Server

transkribus-mcp-server

MCP server for the Transkribus REST API. Manage collections, documents, HTR/OCR recognition, models, and more through the Model Context Protocol.

300 tools across 22 resource domains, with 8 entry points so you can pick the right server for your MCP client's tool limit.

API scope: This server covers the legacy Transkribus TrpServer REST API. The newer Processing API v2 (OIDC auth, /processing/v2, account.readcoop.eu) is intentionally out of scope.

Installation

npm install -g @lazyants/transkribus-mcp-server

Or run directly:

npx @lazyants/transkribus-mcp-server

Configuration

Transkribus uses session-based authentication. You can authenticate in two ways:

Option 1: Username + Password (auto-login)

export TRANSKRIBUS_USER=your-email@example.com
export TRANSKRIBUS_PASSWORD=your-password

The server will automatically log in and manage the session.

Option 2: Direct session ID

export TRANSKRIBUS_SESSION_ID=your-session-id

Use this if you already have a valid session from the Transkribus platform.

Entry Points

Use split servers to reduce context size — pick only the splits you need.

    "transkribus": {
      "command": "npx",

Security

• Never commit your credentials to version control
• Use environment variables or a .env file (excluded via .gitignore)
• Session IDs expire — prefer username/password for long-running setups

Releasing

Releases ship via the GitHub Release event. Maintainer flow:

1. Bump the version in package.json and server.json (npm run check-versions enforces alignment between package.json#/version and server.json#/packages[0].version).
2. Update CHANGELOG.md.
3. Commit, then gh release create vX.Y.Z --notes-from-tag (or write release notes inline).
4. The Publish to npm + MCP Registry workflow runs automatically: it npm publishes with provenance, polls the registry until the tarball is available, then pushes the matching server.json to the MCP Registry via mcp-publisher.

The workflow skips npm publish cleanly if the version is already on npm (cutover guard for releases that were partially published manually).

npm authentication

Publishing uses npm Trusted Publishing: the workflow's GitHub OIDC token (id-token: write) is exchanged for a one-shot publish token at runtime. No NPM_TOKEN secret needs to live in the repo.

The binding is configured in the npm web UI (package → Trusted Publishers): provider GitHub Actions, organization lazyants, repository transkribus-mcp-server, workflow publish-registry.yml.
