Documentation.
Without the guesswork.

One endpoint.
Better context.

Docsy speaks Streamable HTTP MCP. Point a compatible client to the public endpoint, then ask it to resolve a library and retrieve documentation.

{
  "mcpServers": {
    "docsy": {
      "url": "https://docsy.remcp.site/mcp"
    }
  }
}

Works with your tools.

Use the connection configuration above with any editor or agent that supports remote Streamable HTTP MCP servers. Exact settings vary by client; the Docsy CLI can generate configurations for supported editors.

Simple HTTP requests.

Prefer an ordinary REST call? The public retrieval API uses the same index as MCP. Resolve a library ID before querying its documentation.

Resolve a library

curl --get 'https://docsy.remcp.site/v2/libs/search' \
  --data-urlencode 'libraryName=React' \
  --data-urlencode 'query=React useEffect cleanup'

Query its documentation

curl --get 'https://docsy.remcp.site/v2/context' \
  --data-urlencode 'libraryId=/facebook/react' \
  --data-urlencode 'query=How do I clean up useEffect?' \
  --data-urlencode 'type=json'

Set type=txt for agent-ready plain text. Set type=json for structured results and original source links. Use a versioned library ID such as /org/project/v1.2.3 when available.

From terminal to code.

The open-source CLI and SDK are available in the Docsy repository ↗. The CLI includes setup commands for several MCP clients and a direct documentation search workflow.

docsy setup --cursor
docsy setup --claude
docsy setup --codex

docsy library react "useEffect cleanup"
docsy docs /facebook/react "useEffect cleanup"

TypeScript SDK

import { Docsy } from "@docsy/sdk";

const docsy = new Docsy({
  baseUrl: "https://docsy.remcp.site",
  apiKey: process.env.DOCSY_API_KEY
});

const libraries = await docsy.searchLibrary(
  "How do I configure middleware?", "Express"
);
const docs = await docsy.getContext(
  "JWT middleware example", libraries[0].libraryId
);

See the repository’s CLI guide ↗ and SDK guide ↗ for setup and additional options.

Your context.
Your control.
