Redmine CLI with MCP server and skill pack
redmine-cli gives you a terminal client for Redmine issue, time, project, and account workflows. It also exposes those same actions to agents through an agent skill and an MCP server, so you can use the tool yourself or let Claude Code, Codex, or Gemini CLI call it.
Builders who manage Redmine work and want one command set for both terminal use and agent calls.
You can manage Redmine tasks from the terminal and let your agent call the same operations without re-learning the workflow.
What it does
Terminal Redmine commands
Provides commands such as `redmine auth login`, `redmine issues list`, `redmine issues view`, and `redmine time log`.
Agent skill pack
Ships a `SKILL.md`-based skill that teaches agents the CLI details like output formats, name resolution, pagination, and common workflows.
MCP server
Exposes Redmine actions as typed tool calls through `redmine mcp serve`, with read-only defaults and allow/deny controls.
Claude Code and Codex plugin manifests
Includes plugin files under `.claude-plugin/` and `.codex-plugin/` for marketplace install flows.
Completion and release tooling
Includes shell completions, update flow, and Go release/install scripts for local use and distribution.

Using with AI Agents
redmine-cli ships an Agent Skill (the open SKILL.md standard, supported by 35+ agents) and a built-in MCP server. Both are vendor-neutral - pick the one-liner that matches your tool:
| Tool | One-line install |
|---|---|
| Any agent (skill) | npx skills add aarondpn/redmine-cli |
| Any MCP host | redmine mcp serve (then add to host config) |
| Claude Code | /plugin marketplace add aarondpn/redmine-cli then /plugin install redmine |
| Codex CLI | codex plugin marketplace add aarondpn/redmine-cli then /plugins (install Redmine from the added marketplace) |
| Gemini CLI | gemini extensions install https://github.com/aarondpn/redmine-cli |
The skill teaches the agent the non-obvious parts of the CLI (output formats, name resolution, pagination, common workflows). The MCP server exposes the same operations as typed tool calls, read-only by default, with per-group / per-tool allow- and deny-lists.
Full configuration, host-specific snippets (Claude Desktop, Cursor, Zed, VS Code), and write-tool gating: see the AI Agent Integration guide.
Development
Local E2E testing against a real Redmine instance (Docker, supported on Redmine 4.2, 5.1, 6.1, 7.0): see e2e/README.md.
