Spiderbrain

Overview

Spiderbrain is a Model Context Protocol (MCP) server: Deterministic context layer for your codebase: change impact, blast radius, answers with receipts. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.

You can run Spiderbrain two ways: connect to the hosted endpoint at https://mcp.spiderbrain.ai/mcp with no local install, or run it on your own machine via the npm package spiderbrain. Configuration happens through environment variables — you'll need SPIDERBRAIN_ROOT. The current release is v0.2.3, published under the MIT license, with source at aabhisrv/Spiderbrain.ai-Coremind on GitHub.

You'll find Spiderbrain in the Development category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
