MCP server exposing the Datacrawl API (search/fetch/extract) as agent tools over stdio.
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":"datacrawl-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.

# datacrawl-mcp MCP server for the [Datacrawl API](https://datacrawl.dev) — gives any MCP client (Claude Desktop, Claude Code, etc.) three tools: `search`, `fetch`, `extract`. Credit-metered; every result reports `credits_remaining`. ## Install ```bash pip install datacrawl-mcp # or: uv tool install datacrawl-mcp ``` Get an API key at https://datacrawl.dev/portal/signup (free tier, no card). ## Configuration (env only — the key is never stored in files you commit) - `DATACRAWL_API_KEY` (required) — your API key. - `DATACRAWL_BASE_URL` (optional) — defaults to `https://datacrawl.dev`. ## Claude Desktop Add to `claude_desktop_config.json`: ```json { "mcpServers": { "datacrawl": { "command": "datacrawl-mcp", "env": { "DATACRAWL_API_KEY": "ak_YOUR_KEY" } } } } ``` ## Claude Code ```bash claude mcp add datacrawl -e DATACRAWL_API_KEY=ak_YOUR_KEY -- datacrawl-mcp ``` ## Errors you might see - `DATACRAWL_API_KEY is not set` — export the env var (see above). - `429 insufficient credits` — you're out of credits for the month; see https://datacrawl.dev/portal/docs/pricing. - `429 rate limit exceeded` — per-key rps cap; retry after a second.
