What is the Spring Openproject MCP server?

Spring Openproject MCP server exists for a simple reason — assistants are far more useful when they can act on Spring Openproject directly instead of describing what you should do. MCP server to manage OpenProject work-packages realized in Java. The server acts as a proxy to your OpenProject API. The user's' OpenProject API token is used for authentication (not stored in the container!).

Setting it up

Installation goes through your MCP client rather than a global install: point it at docker.io/tmskln/spring-openproject-mcp-server on a container image and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

What the assistant can call

Once Spring Openproject is connected, these are the calls the assistant has available:

  • build — The build tool exposed by this server

Configuration and credentials

You will need 2 environment variables: OPENPROJECT_URL, OPENPROJECT_ALLOW_HEADER_BASE_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the spring openproject mcp server does with a few real requests.

Choosing this one

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Spring Openproject's toolset — build — is a fair guide to whether it matches your workflow. It is maintained by tmskln; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Frequently asked questions

It connects Spring Openproject to MCP-compatible AI assistants such as Claude and Cursor, exposing 1 tool (build) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Spring Openproject directly.
