Three ways to use doc2mcp

Surface	Best for	Start here
Web	Instant convert in the browser	doc2mcp.site
CLI	Terminal + one-shot install into Cursor	npm i -g doc2mcp
SDK	Code, CI, LangChain / LangGraph / agents	doc2mcp-sdk

API keys always come from doc2mcp.site (User PAT + project token). The SDK has no separate login.

---

The pipeline

Docs URL → crawl → analyze → MCP tools → hosted endpoint → Cursor / Claude / LangChain / LangGraph.

---

1) Web (normal)

1. Sign in at doc2mcp.site/login
2. Paste a docs URL (Stripe, LangChain, Mintlify, GitHub…)
3. Copy the hosted MCP URL + Bearer token into Cursor / Claude / VS Code

{
  "mcpServers": {
    "my-docs": {
      "url": "https://doc2mcp.site/api/mcp/{project_id}/mcp",
      "headers": { "Authorization": "Bearer <project-token>" }
    }
  }
}

---

2) CLI

npm install -g doc2mcp
doc2mcp login                 # creates User PAT (d2mcp_pat_…)
doc2mcp https://docs.example.com

Lists the same projects as the dashboard. Install helpers for Cursor / VS Code / Claude / Windsurf.

---

3) SDK (doc2mcp-sdk)

npm i doc2mcp-sdk

import { Doc2MCP } from "doc2mcp-sdk";

// User PAT from doc2mcp.site / `npx doc2mcp login` — SDK has no auth of its own
const client = new Doc2MCP({ token: process.env.DOC2MCP_API_TOKEN! }); // Settings → d2mcp_usr_…

const ready = await client.convertAndWait({
  sourceUrl: "https://js.langchain.com/docs",
});

const answer = await client.callToolText({
  mcpUrl: ready.mcp.url,
  mcpToken: ready.mcp.token, // project token d2mcp_…
  name: "search_documentation",
  arguments: { query: "how do runnables work?" },
});
