[!WARNING]

## CodeWeaver is no longer maintained

We're really proud of CodeWeaver and think it's pretty awesome, but we can't maintain it anymore.

We're focused on something else.

CodeWeaver is (was?) a sophisticated, smart, code search tool with wide provider support.

and it's still licensed under your choice of MIT or Apache-2.0.

So please, fork it and build something great!

CodeWeaver

Exquisite Context for Agents — Infrastructure that is Extensible, Predictable, and Resilient.

[![Python Version][badgepython]][linkpython] [![License][badgelicense]][linklicense] [![Release][badgerelease]][linkrelease] [![MCP Compatible][badgemcp]][linkmcp]

[Documentation][navdocs] • [Installation][navinstall] • [Features][navfeatures] • [Comparison][navcomparison]

What It Does

CodeWeaver gives Claude and other AI agents precise context from your codebase. Not keyword grep. Not whole-file dumps. Actual structural understanding through hybrid semantic search.

CodeWeaver is Professional Context Infrastructure. With 100% Dependency Injection (DI) and a Pydantic-driven configuration system, it provides the reliability and extensibility required for industrial-grade AI deployments.

Example:

Without CodeWeaver:
  Claude: "Let me search for 'auth'... here are 50 files mentioning authentication"
  Result: Generic code, wrong context, wasted tokens

With CodeWeaver:
  You: "Where do we validate OAuth tokens?"
  Claude gets: The exact 3 functions across 2 files, with surrounding context
  Result: Precise answers, focused context, 60-80% token reduction

CodeWeaver is no longer in alpha!

Early Release (0.x): CodeWeaver is in active development. APIs may change between minor versions. It's very well-tested but still in 'it works on my machine' territory. [Use it, break it, help shape it][issues].

How CodeWeaver Stacks Up

Quick Reference Matrix

🚀 Getting Started

Quick Install

Using the CLI with [uv][uv_tool]:

# Add CodeWeaver to your project
uv add code-weaver

# Initialize with a profile (recommended uses Voyage AI)
cw init --profile recommended

# Verify setup
cw doctor

# Start the background daemon
cw start

📝 Note: cw init supports different Profiles:

- recommended: High-precision search (Voyage AI + Qdrant)

- quickstart: 100% local, private, and free (FastEmbed + Local Qdrant)

Codeweaver: common questions

Is Codeweaver MCP server safe?: With care: it is graded C, so read the findings first (62/100). Read the Codeweaver safety report
How do I install Codeweaver?: It runs on your machine. Copy the Claude Code, Cursor, VS Code or Claude Desktop config from the install section.
Does Codeweaver need an API key?: Yes. The registry entry asks for CODEWEAVER_EMBEDDING_API_KEY, CODEWEAVER_RERANKING_API_KEY, CODEWEAVER_VECTOR_STORE_API_KEY, OPENAI_API_KEY and 10 more.
Is Codeweaver maintained?: The last commit was 141 days ago (2026-06-16). The latest release is v0.1.0-alpha.3.
What can I use instead of Codeweaver?: Servers from other publishers that do the same job: Arxiv MCP server, Socraticode MCP server and DocsMint MCP server.
How does Codeweaver compare with other Web search MCP servers?: safety score 62/100 (higher than 14% of 3,470 Web search servers); github stars 12 (more than 86% of 1,786 Web search servers); downloads a week 40 (more than 26% of 827 Web search servers with a package). Full comparison.
