How to Use the R2R MCP in Cline

Q: How does Cline use R2R for complex tasks?

Cline uses ragquery to ground its reasoning in your documents. It treats the output as source material for every file it writes.

Q: Do I need to configure R2R inside Cline?

Add the endpoint to your clinemcpsettings.json file. Once saved, Cline connects to the MCP Server and maps the tools automatically.

Q: What happens if the R2R server goes offline during a Cline task?

Cline will report a tool execution failure. Use gethealth to verify the status, then restart your R2R instance to restore the connection.

Give Cline direct access to your R2R engine for autonomous document retrieval and RAG tasks in VS Code.

Perplexity

Cline executes RAG tasks on demand

Cline uses `rag_query` to build context for your coding tasks. Tell it what you need, and it fetches the documentation or logic from your R2R engine. It doesn't just read the output. Cline takes the data, creates the necessary files, and runs the tests required to verify the implementation.

Automated vector search for Cline

Use `search` to find relevant information across your entire document set. Cline triggers this tool to pinpoint exact code patterns or business rules. This removes the need for manual grep or global searches. Cline brings the specific vector-matched segments into your current workspace.

R2R document control in Cline

Manage your knowledge base by calling `list_documents` and `get_document` from the Cline sidebar. It keeps track of what is indexed and what needs updating. Cline uses these tools to ensure it has the latest context before writing code. It prevents hallucinations by grounding its work in your actual R2R data.
