How to Use the R2R MCP in Claude Code

Q: How do I run a R2R search from Claude Code?

Use the tool-calling interface in your terminal. Call search with your query string to get semantic results directly in your shell.

Q: Can I use R2R tools in my Claude Code scripts?

Yes. The MCP Server allows you to chain ragquery and other operations within shell scripts, provided the server is connected via the standard transport.

Q: How do I verify the R2R connection in Claude Code?

Run claude mcp list to ensure the server is registered. Then execute gethealth to confirm the R2R engine is responding.

Q: Does Claude Code support all R2R tools?

Yes. All six tools, including listdocuments and getdocument, are fully accessible once you add the server via claude mcp add.

Connect Claude Code to your R2R engine for terminal-based RAG and vector search in your CI/CD pipelines.

Headless RAG via Claude Code

Execute `rag_query` directly from your terminal. Use it in shell scripts or CI/CD jobs to generate context-aware reports from your R2R engine. It returns structured data ready for piping into other CLI tools. Automate your knowledge retrieval without a GUI.

Terminal-based vector search with Claude Code

Call `search` to find document chunks based on semantic similarity. It is ideal for searching massive logs or documentation sets stored in R2R. Integrate this into your workflow to verify documentation presence before deploying. Claude Code runs the search and displays the results in your standard output.

Monitor R2R via Claude Code

Use `get_health` to check your R2R engine availability within your automated pipeline. It provides a simple status check for your infrastructure. Combine this with `list_collections` to audit your data availability before running heavy ingestion jobs. It keeps your automation robust.
