Deterministic, self-hosted MCP server exposing structured Dataform pipeline context (lineage, schemas, layers) to coding agents
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"dataform-context-mcp","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.

At the root of **your Dataform repo**, create or extend `.mcp.json` (template: [`.mcp.json.example`](.mcp.json.example)): ```json { "mcpServers": { "dataform-context": { "type": "stdio", "command": "/opt/homebrew/bin/uvx", "args": ["--from", "dataform-context-mcp@latest", "dataform-context", "serve"] } } } ``` That's it: no clone, no `--repo` (the server indexes the current directory). Open a Claude Code session in the repo and type `/mcp`: `dataform-context` should show as connected. First call takes ~15 s (initial compilation), then ~10 ms. > [!IMPORTANT] > **Absolute path to `uvx` is required**: a bare `"command": "uvx"` fails (`ENOENT`) > when the agent is launched from a non-login shell whose PATH…
