Context Atlas tools (3)

write = sends, deletes, buys or posts
  • get_topicFree

    All sources (llms.txt, docs, MCP servers, skills, rules), detection signals and the role of one tool, by id such as `vercel`, `nextjs` or `drizzle`.

  • list_topicsFree

    Every tool in the catalog with its id, name, role and region, without sources. Use it to find candidates per role, then get_topic and their llms.txt sources to compare them.

  • searchFree

    Full-text search over tools (topics) and their sources. Matches names, roles, regions, detection signals (files, dependencies, env vars), source titles and URLs. Every word must match, as a prefix.

What the publisher says

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

Context Atlas

Live: https://contextatlas.dev (the old https://contextatlas.levinstaudt.workers.dev redirects there with a 301)

Chart a tech stack, or find the right sources for the one you have. Context Atlas collects the llms.txt indexes, docs, MCP servers, agent skills, rule files and CLIs that vendors publish for coding agents, grouped into cloud providers, frameworks, standards and CLIs.

The site only links to the sources; every source belongs to its vendor.

  • / lists every source, filterable by search and by kind (the map legend).
  • /agent has a copy button for a one-sentence prompt, either for an existing project (detect the stack, then follow the matching sources) or for a new one (propose a stack), and the command to add the MCP server.
  • /llms.txt holds the agent instructions and the full catalog; the prompt only links to it. /atlas.json has the same data as JSON.
  • /llms/.txt holds a single topic, for agents that need only one tool's sources.
  • /mcp is a stateless MCP server (Streamable HTTP) with the tools search, gettopic and listtopics: claude mcp add --transport http contextatlas https://contextatlas.dev/mcp.
  • /api/topics, /api/topics/ and /api/search?q=&kind=&limit= are the JSON API for the CLI (#13).

Add a source

All content lives in packages/core/src/catalog.ts. Add a Source to an existing topic, or a new Topic with a role and signals (how an agent detects it in a repo: file(...), dep(...), env(...) or hint(...)). Bump updatedAt. Then run bun run check; the catalog tests catch duplicate ids, bad URLs and malformed signals. The add-source skill has the details.

Everything the site serves is read from SQLite, which bun run seed (and every deploy) rebuilds from that file.

Develop

Bun workspaces, Hono in front for the agent files, the API and MCP, React Router (framework mode, server-rendered, Vite) for the pages, SQLite through Drizzle with FTS5 search, the MCP TypeScript SDK and Tailwind CSS.

bun install
bun dev          # http://localhost:3000, hot reload for the pages, restart on server changes
bun run check    # lint, typecheck, tests: run before every commit
bun run build    # dist/: single binary (server + pages) + public/ + drizzle/
bun run deploy   # deploy main to the VPS through GitHub Actions
