Live codebase intelligence for AI agents: conventions, blast radius, import graphs, git insights.
Most developer tooling work still happens through a UI a human drives. Sourcebook MCP server moves it into the conversation instead. Live codebase intelligence for AI agents: conventions, blast radius, import graphs, git insights.
A safety layer for code changes. sourcebook analyzes git diffs for completeness — flags files that should've been modified but weren't. Rules-based structural detection plus AI-powered semantic analysis. Zero false positives on clean diffs.
Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
Configuration is passed through the environment: ANTHROPIC_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
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. It is maintained by maroondlabs; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against Sourcebook's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
Add to your MCP client:
```json
{
"mcpServers": {
"sourcebook": {
"command": "npx",
"args": ["-y", "sourcebook", "serve", "--dir", "/path/to/your/project"]
}
}
}Configuration as documented by the project. Restart the client after saving.
