Codeweave MCP Server

Give your AI agent structured code understanding - not just file dumps. CodeWeave is an MCP server that gives AI agents cheap, precise code intelligence. Instead of dumping entire files into context, your agent queries local indexes - AST, call graph, type graph, hybrid semantic search - and gets back only what it needs. Its 3 documented tools cluster into semantic, reindex, read & search.

People who work with ast, call graph and code analysis and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Codeweave

Claude Code

claude mcp add semihkayan-codeweave-mcp -- npx -y @codeweave/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "semihkayan-codeweave-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@codeweave/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 Apache-2.0 - declared in the repository

npm package @codeweave/mcp - the @codeweave scope differs from the repo owner (semihkayan); confirm it's the project's official package

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

03 · What Codeweave 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 search by meaning - finds functions even when you don't know exact names. Hybrid vector + keyword search with density-based reranking, and index health dashboard: file/function counts, embedding status, call graph stats, language breakdown.

The 3 tools it gives your agent

Extracted from the project's README - what codeweave lets an agent do.

semantic_search: - Search by meaning - finds functions even when you don't know exact names. Hybrid vector + keyword search with density-based reranking.
reindex: - Manually trigger index update. Usually unnecessary - file watcher auto-reindexes on changes.
get_index_status: - Index health dashboard: file/function counts, embedding status, call graph stats, language breakdown.

06 · Codeweave FAQ

Is Codeweave still maintained?

Yes - as of 2026-09-18, its last commit was 2026-05-26. We re-verify nightly.

What can Codeweave do?

How do I install Codeweave?

Run `npx -y @codeweave/mcp`. You can also paste the ready-made client config above.

Does Codeweave run locally?

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
