Aidex MCP Server

The persistent brain for AI coding agents. AiDex is an MCP server that gives AI coding assistants a memory, semantic search, and live telemetry - local-first, model-agnostic. Works with any MCP-compatible AI assistant: Claude Code, Claude Desktop, Cursor, Windsurf, Gemini CLI, VS Code Copilot, and more. Its 29 documented tools cover aidex, global, init, signatures.

People connecting coding agent tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Aidex

Claude Code

claude mcp add cscsoftware-aidex -- npx -y aidex-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "cscsoftware-aidex": {
      "command": "npx",
      "args": [
        "-y",
        "aidex-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package aidex-mcp - unscoped; check the name against the project README before installing

registry namespace io.github.CSCSoftware is GitHub-verified and matches the repo owner

03 · What Aidex can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can index a project (creates .aidex/), search by term (exact/contains/starts_with), get one file's classes + methods, and get signatures for multiple files (glob).
