# Developer research

Use `firecrawl_developer_search` through the Firecrawl MCP connection. If it is
deferred, discover it with the host's tool search. Include the library, version,
and exact error or symbol when known. Read the matched passages and source URLs.
Developer searches are billed per request.

Distinguish official documentation from issues, proposals, and merged pull
requests. A merged fix does not establish that it shipped in the user's version.
Use `firecrawl_scrape` on a source URL when the passage lacks the needed context.
Use `firecrawl_search` when the relevant source is outside the index or the index
does not resolve the question.

Answer from the retrieved evidence, cite the relevant sources, and state any
unverified version or release boundary. Respect the user's source and tool
choices. Report connection or authentication errors.
