Overview

What is MantisBT MCP Server?

MantisBT MCP Server connects your Mantis/MantisBT bug tracker to Claude Code and other MCP-compatible AI clients via the Model Context Protocol. It lets developers read, create, and update issues, notes, attachments, tags, and relationships directly from their AI assistant, eliminating the need to switch between editor and browser.

How to use MantisBT MCP Server?

Zero‑install setup via npx @dpesch/mantisbt-mcp-server — just configure the environment variables MANTIS_BASE_URL and MANTIS_API_KEY. The server supports stdio (default) and HTTP (Streamable HTTP) transports, with optional Bearer token authentication for remote or Docker deployments.

FAQ from MantisBT MCP Server

What transports does the server support?

The server supports stdio (default) and HTTP (Streamable HTTP) transports, with optional Bearer token authentication for remote or Docker setups.

Does the server require a specific MantisBT version?

Yes, it requires MantisBT 2.23 or later with the REST API enabled.

How does semantic search work and what are its requirements?

Semantic search runs fully offline using a local embedding model that is downloaded once (~80 MB). It finds issues by meaning rather than exact keyword matches.

How do I install and configure the server?

Use npx @dpesch/mantisbt-mcp-server with no installation step. Set the MANTIS_BASE_URL and MANTIS_API_KEY environment variables.

Where do the issue data and embeddings live?
