Unblocked MCP tools are actively evolving. Tools and their descriptions may change over time.
link_resolver fetches the content behind a URL. Your agent calls it when it already has a link and needs the data at that location. It works with URLs from your connected services, including pull requests, issues, documentation pages, and message threads.

​
When your agent uses it

  • You paste a URL and ask your agent about it, such as a link to an issue with a request to summarize it.
  • Your agent finds a URL in results from another tool and needs to follow it, such as a documentation page referenced in a PR discussion.
  • Your agent needs the full diff or comments on a specific pull request.

​
When your agent uses something else

  • To search for records without a URL, data_retrieval queries by filter.
  • To understand the context around a piece of code, unblocked_context_engine provides organizational context.
  • To investigate a broad topic, research_task summarizes what it finds across sources.
