Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Find llms.txt, docs, MCP servers, skills and CLIs for a tech stack, for coding agents.
These three are never merged into one score: opinions, measurements and popularity are different things.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.
Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.
searchFull-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.
get_topicAll 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_topicsEvery 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.
We check information anyone can see; we have not read the code. Checks that do not apply are left out of the count. · Checked Nov 7, 2026

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 15 days ago.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

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, get_topic and list_topics: 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).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.
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.

| Path | What |
|---|---|
packages/core | Catalog, database schema and migrations, seed, queries, search, llms.txt text. Transport-free. |
apps/server | Hono app: agent files, JSON API, MCP, static files; hands every other path to apps/web. src/main.ts is the binary (seed, serve), src/dev.ts the dev server. |
apps/web | The pages for people: React Router routes, components and styles. Reads the catalog from the server's snapshot, no data logic. See docs/web-frontend.md. |
apps/redirect | Cloudflare Worker that 301s the old workers.dev URL to the new domain. |
deploy/ | systemd unit and VPS scripts. |
scripts/ | Cloudflare setup, VPS access, IndexNow ping and the share image, all from the harness. |
server.json, glama.json | The remote MCP server's entries for the official MCP Registry and Glama. |
docs/deploy.md | Infrastructure and runbook. |
