Codesearch

io.github.SK-DEV-AIPublished by GitHub account SK-DEV-AIv1.0.1Updated Oct 24, 2026

Code, package, docs, paper and vulnerability search. 17 tools, keyless lanes.

Overview

AI-generated overview

Local MCP server that lets an assistant search code, packages, docs, papers, vulnerabilities and Q&A communities across many sources.

What you can do
  • Search code, docs and symbols inside indexed npm, PyPI and crates dependencies, and list or read their files
  • Analyze a GitHub repository (metadata, code quality, wiki architecture) and search within it, list its file tree and read files
  • Query package registries for versions, dependencies and advisories, and get composite package intelligence including changelog and upgrade review
  • Look up vulnerabilities, licenses and latest versions, with NVD enrichment
  • Fetch documentation, Stack Overflow answers, Hacker News discussions and academic papers
  • Enrich result lists with full content, deduplicate and rerank, plus a connectivity check
When to use it
Useful when you need research across code, packages, documentation, papers and vulnerability data in one place, for example evaluating a dependency, reviewing an upgrade, or getting oriented in an unfamiliar repository.
Requirements
Runs locally over stdio as a Python package (Python 3.14+), installed from PyPI or run via Docker. Many lanes work without keys; optional keys such as GITHUB_TOKEN, CONTEXT7_API_KEY, TAVILY_KEYS, S2_API_KEY, SE_API_KEY, SOFA_KEY, LI_KEY, OSS_TOKEN, FIRECRAWL_KEYS, NV_KEY and GROQ_API_KEYS raise rate limits or enable extra lanes. Network access required.
Before you install
Several optional secrets are read from environment variables; keep them out of committed files. The all-extras install pulls multi-GB browser/OCR dependencies. It fetches user-supplied URLs, though the README says these are SSRF-validated. Results may be unranked without the optional local reranker.

Installation

In SourceWeft

  1. Open Codesearch in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

codesearch MCP Server

mcp-name: io.github.SK-DEV-AI/codesearch

Companion agent skills: SK-DEV-AI/skills · npx skills add SK-DEV-AI/skills

Code, package, docs, and paper search MCP server. Per-package source navigation (npm/PyPI/crates), per-repo intelligence (GitHub URL or owner/repo), Q&A communities, vulnerability data, documentation, and academic papers — with embedding dedup and a local cross-encoder reranker.

Tools (17)

  • analyze — Start here for unfamiliar repos: GitHub metadata + code quality + wiki architecture in one call (10–15s).
  • search_all — Broad multi-source discovery (Context7, GitHub, DeepWiki, CodeWiki, SO, HN, Libraries.io, npm, DevDocs, Semantic Scholar, Tavily…). For surgical single-source work call the tool below directly.
  • code_search — Search code/docs/symbols across indexed dependencies (target=npm:express). npm/PyPI/crates only — for GitHub repos use searchcode or analyze.
  • code_files / code_read — List files / read a file in an indexed dependency by package spec.
  • searchcode — Per-repo intelligence: analyze (overview), search (code within the repo), findings (quality issues), file_tree, get_file. Needs repository for every action. Free, no auth.
  • wiki — Repo architecture Q&A via DeepWiki + CodeWiki. Single repo (owner+repo) or up to 10 repos (repos).
  • search_package — Raw registry queries: versions, dist-tags, deps.dev graphs, advisories (version='latest' OK). For composite intelligence use pkg.
  • pkg — Composite package intelligence: metadata, changelog, upgrade review (vulns + changelog + deps diff), file list/read.
  • search_libraries — Libraries.io metadata and source rank. Compare dependency candidates, find the repo behind a package.
  • vulns — Sonatype Guide + keyless OSV.dev fallback: scan (needs platform+name+version), detail (needs vuln_id; enriched with NVD CVSS/CWE/references), latest_version/license (need purl).
  • docs — Docs with smart fallback (Context7 → ReadTheDocs → llms.txt → DevDocs); then fetch(url) or devdocs_fetch_content for full pages.
  • so_search — Stack Overflow: stackexchange (authoritative resolved answers) or sofa (fresher agent content, needs SOFA_KEY).
  • hn — Hacker News discussion and sentiment (search, stories, items, users).
  • papers — Academic papers. Prefer action=search (S2 → arXiv → OpenAlex → CORE fallback chain); arxiv_search is single-source and rate-limited.
  • enrich — Fetch full content for a result list from any search tool, dedup + rerank.
  • ping — Connectivity check. Use before expensive calls when uncertain.

Setup

Requires Python 3.14+.

bash
python3 -m venv .venv && source .venv/bin/activatepip install -r requirements.txtcp run.example run   # fill in your API keys (run is gitignored — never commit it)chmod +x run

Point your MCP client at run (stdio):

json
{ "codesearch": { "command": "/path/to/codesearch/run" } }

Install from PyPI

bash
pip install skdev-codesearch-mcp          # core install, smallpip install skdev-codesearch-mcp[all]     # + browser/OCR/extract extras (multi-GB)

The codesearch-mcp console script speaks MCP over stdio:

json
{ "codesearch": { "command": "codesearch-mcp" } }

Docker

bash
docker build -t codesearch-mcp .docker run --rm -i codesearch-mcp

Keys are passed at run time, never baked in: -e GROQ_API_KEYS=.... Heavy extras: docker build --build-arg EXTRAS="[all]" -t codesearch-mcp .

Notes

  • Reranker (optional, local): shared with the websearch server — one cross-encoder worker over a Unix socket. Without it, results return unranked; everything still works.
  • Caching: per-source file caches with TTLs; repeat queries are cheap.
  • Safety: all user-URL fetches are SSRF-validated (private-IP blocking + redirect-hop revalidation).

SourceWeft started this package once in an isolated sandbox, without credentials, to list its tools. That failed: the package type cannot run in the sandbox.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
