What it can access
- An MCP server is a program your AI app starts and talks to. A local one runs with your user's permissions: it can see the files, environment variables and network your account can.
- Based on its description and topics, it likely needs to connect to a database.
- Based on its description and topics, it likely needs to read or change your workspace data (docs, tickets, CRM).
Before you install
- Give it a read-only database user unless it must write.
- Connect it to a test workspace before your real one.
- Pin the version you reviewed instead of always installing the latest release.
- Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.
- Maintained by xerj-org on GitHub, 18,550 stars and 1,408 forks. Popularity is not proof of safety.
- Last code change: Nov 1, 2026.
- Open-source license: Apache-2.0.
