# Use the Docs MCP Server

> Connect an AI coding tool to the read-only NoLimitNodes documentation server.

Canonical: https://nolimitnodes.com/docs/guides/mcp

The NoLimitNodes MCP endpoint gives coding agents direct access to docs, stream catalogs, schemas, and API specifications.

## Endpoint

```text
https://nolimitnodes.com/mcp
```

The server uses Streamable HTTP. It accepts JSON-RPC requests over `POST`. No NoLimitNodes API key is required because every exposed operation reads public documentation.

## Available tools

- `search_docs` searches documentation by title, description, path, and body text.
- `get_doc` returns one documentation page as Markdown.
- `list_stream_topics` lists Enhanced Streams or Program Streams topics.
- `get_topic_schema` returns the JSON Schema for one stream topic.
- `get_api_specs` lists OpenRPC, AsyncAPI, OpenAPI, proto, and catalog URLs.

The server never sends RPC requests, starts subscriptions, or reads your account.

## Test the connection

```bash
curl https://nolimitnodes.com/mcp \
  -H "content-type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "initialize",
    "params": {
      "protocolVersion": "2025-06-18",
      "capabilities": {},
      "clientInfo": {
        "name": "docs-test",
        "version": "1.0.0"
      }
    }
  }'
```

Call `tools/list` after initialization. Your client handles these requests when you add the endpoint through its MCP settings.

## Limits

Search and catalog results use bounded page sizes. Use a cursor for long topic lists. The server rejects unknown origins and write operations.
