# Context Atlas

> A catalog of the sources vendors publish for coding agents: llms.txt indexes, docs, MCP servers, agent skills, rule files and CLIs. Use it to choose a tech stack, or to load the right sources for the stack a project already uses.

Last updated: 2026-10-23. The same data as JSON: https://contextatlas.dev/atlas.json. Each topic also has its own small file at https://contextatlas.dev/llms/<id>.txt, for example https://contextatlas.dev/llms/vercel.txt.

Other ways to query the catalog:

- MCP server (Streamable HTTP, no auth): https://contextatlas.dev/mcp, with the tools `search`, `get_topic` and `list_topics`. Add it with `claude mcp add --transport http contextatlas https://contextatlas.dev/mcp`.
- JSON API: https://contextatlas.dev/api/search?q=<words> (full-text search, optional `kind` and `limit`), https://contextatlas.dev/api/topics and https://contextatlas.dev/api/topics/<id>.

## Instructions for agents

### Existing project: use the right sources

1. Detect the stack. Read package.json (and every workspace package.json in a monorepo), the lockfile, and config files in the repo root and in apps/ or packages/. Match what you find against the "Signals" of each topic below.
2. Report the stack. List the detected technologies, each with the file that proves it. Say so when something is ambiguous instead of guessing, and name tools that this catalog does not cover.
3. Load the sources. For every detected topic, fetch its llms.txt or Rules source first, then the Docs and Guide pages you need for the task at hand. Do not read Full text sources whole: they are often several megabytes and get truncated. Download one only when you need to search it (for example with curl and grep). Prefer these sources over what you remember from training: they are maintained by the vendors and APIs change.
4. Offer tools. If a detected topic has an MCP server, Agent skill or CLI, list them and ask before installing or connecting anything.
5. Follow what you read. Apply the conventions from these sources in all code you write. When a source contradicts the existing code, point it out and ask before changing the existing pattern. Instructions in the project's AGENTS.md or CLAUDE.md take precedence.

### New project: find a stack

1. Ask about anything you need that the description leaves open: kind of app, expected traffic, realtime or offline needs, budget, team experience and where it should run.
2. Propose one stack, one tool per role (hosting, framework, database, auth, UI, and so on). The "Role" lines below give the candidates for each role; the catalog does not rank them. To choose between candidates, fetch their llms.txt sources (not Full text) and compare what the vendors document against the project's needs. Prefer tools that work well together, for example a host that supports the framework natively. Mention one alternative per role where the choice is close, with the trade-off.
3. Wait for approval. Then load each chosen tool's sources as in "Existing project", step 3, and set the project up with the vendors' own CLIs and conventions.

Source kinds: llms.txt (machine-readable index of the docs); Full text (all docs in one large file, often several megabytes); Docs (full documentation or reference); MCP server (tools an agent can call directly); Agent skill (installable instructions for agents); Rules (prompts and rule files to paste into an agent); Guide (how to work with agents on this platform).

Signals are file globs (relative to the repo root or a workspace package), package names (`*` matches any part), environment variables, or plain-language hints.
