Ctx tools (6)

write = sends, deletes, buys or posts
  • get_fileFree

    Return the full text of a single file in a repository, by path. Use after list_files or search_context to drill in.

  • list_filesFree

    List the text files ctx would include for a repository (after stripping binaries, lockfiles and build dirs), with their byte sizes. Cheap way for an agent to see the layout before packing.

  • pack_docsFree

    Crawl a documentation site from a start URL and return it as one agent-ready context blob: each page extracted to clean Markdown, concatenated with its URL. Stays within the same site section; bounded by depth and page count. Use max_tokens to fit a budget.

  • pack_repoFree

    Fetch a GitHub repository and return it as one agent-ready context blob: text files concatenated with clear "==== path ====" headers, binaries/lockfiles/build dirs stripped, with a token estimate. Use include/exclude globs to focus, and max_tokens to fit a budget.

  • search_contextFree

    Search a GitHub repository and return only the passages that match a query — each with its file path, line number and a relevance score. Far more token-efficient than pack_repo when you need a specific detail (e.g. "where is auth handled?").

  • search_docsFree

    Crawl a documentation site and return only the passages that match a query — each with its page URL, line and a relevance score. Token-efficient way to answer a question from docs without packing the whole site.

What the publisher says

From the Ctx repository's README, as published. We do not edit it. Read it on GitHub

ctx.vanshul.com

A public Model Context Protocol (MCP) server, running as a Cloudflare Worker, that turns a GitHub repository or a documentation site into agent-ready context. Point an AI agent at it and it can pack a whole repo (or crawl a docs site) into one token-counted blob — or search it and get back only the relevant passages, each with its file/URL and line.

It's the agent-first companion to mcp/: where mcp reads a single web page, ctx reads whole repos and doc sites. The repo pipeline fetches, gunzips and parses the tarball in-process; docs extraction reuses Mozilla Readability + Turndown.

Endpoint

POST https://ctx.vanshul.com/mcp     # JSON-RPC 2.0 (MCP)
GET  https://ctx.vanshul.com/health  # { ok: true, tools: [...] }

Tools

repo is owner/repo, owner/repo/ref, or a github.com URL. url (for the docs tools) is an absolute http(s) docs page to start crawling from.

Connect from an MCP client

{ "mcpServers": { "ctx": { "url": "https://ctx.vanshul.com/mcp" } } }

Stdio-only clients bridge with npx mcp-remote https://ctx.vanshul.com/mcp.

Add it to your client

  • Cursor — Settings → MCP → Add new server, or drop this into ~/.cursor/mcp.json:
{ "mcpServers": { "ctx": { "url": "https://ctx.vanshul.com/mcp" } } }
  • Claude Desktop — add the same block to claudedesktopconfig.json (Settings → Developer → Edit Config). If your version is stdio-only, use:
{ "mcpServers": { "ctx": { "command": "npx", "args": ["mcp-remote", "https://ctx.vanshul.com/mcp"] } } }
  • Continue / VS Code — add ctx with URL https://ctx.vanshul.com/mcp to your MCP servers config.

Try it with curl

# Pack a repo, capped to 8000 tokens
curl -s https://ctx.vanshul.com/mcp -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call",
       "params":{"name":"pack_repo","arguments":{"repo":"sindresorhus/slugify","max_tokens":8000}}}'

# Search a repo for just the relevant passages
curl -s https://ctx.vanshul.com/mcp -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/call",
       "params":{"name":"search_context","arguments":{"repo":"sindresorhus/slugify","query":"replace separator"}}}'

Ctx: common questions

Is Ctx MCP server safe?
Yes, by our scan: it is graded A (91/100). Read the Ctx safety report
How do I install Ctx?
It runs remotely at ctx.vanshul.com. Add it to Claude Code, Cursor, VS Code or Claude Desktop with the snippets above, or call it through the mcp.market gateway without installing anything.

Is Ctx maintained?
The last commit was 61 days ago (2026-09-04). The latest release is v1.0.0.
Is Ctx up?
100% of our last 28 checks got an answer. We check remote servers about four times a day.
What can I use instead of Ctx?
Servers from other publishers that do the same job: GitHub MCP server, Gk CLI MCP server and OctoCounts MCP Server. Compare all Ctx alternatives.
How does Ctx compare with other Developer tools MCP servers?
safety score 91/100 (higher than 85% of 1,119 Developer tools servers); tools 6 (the typical Developer tools server has 7); tools that change things 0% (typical: 5%. Fewer write tools means less an agent can break). Full comparison.
