### MCP tool filtering

Codegraph's MCP server exposes 30+ tools by default. For models with a small context window, you can shrink the schema by disabling tools you don't use:

```json
{
"mcp": {
"disabledTools": ["execution_flow", "sequence", "communities", "co_changes"]
}
}
```

Names are matched case-insensitively and a leading `codegraph<digits>_` prefix (e.g. `codegraph2_module_map`) is stripped before comparison. Disabled tools are removed from `tools/list` and any `tools/call` invocation returns `Unknown tool: <name>`. See **[docs/guides/configuration.md#mcp-tool-filtering](docs/guides/configuration.md#mcp-tool-filtering)** for the full tool catalog, and the rest of that guide for every other config option.

## 📖 Programmatic API

Codegraph also exports a full API for use in your own tools:
