Live metrics, not vanity numbers. npm version and monthly-download badges use public npm data; GitHub checks, stars and asset-download badges update independently. For reference, the npm downloads API reported 717 SDK and 846 CLI package downloads for 30 September–29 October 2026 (1,563 package downloads combined, not unique users). The badge values will change over time. GitHub release-asset downloads are not npm downloads.

Why Docsy?

Coding assistants can mix documentation from different versions or give answers without a checkable source. Docsy helps them resolve the right library, find version-specific documentation and return links to the original publisher files or pages.

• Version-aware: ask for a specific release and see which versions are indexed; upstream tags alone do not imply indexed documentation.
• Source-linked: excerpts include origin URLs and, when available, a pinned Git revision.
• Focused: retrieve the relevant passage or request links without loading an entire manual.
• Read-only: no local shell execution, file writes or access to your private repositories.

MCP tools

For example, ask: “Using official React documentation, explain `useEffect` cleanup and cite the original source.”

Quick start

Pick the connection that suits your workflow. The hosted MCP service runs remotely, so you do not need to clone this repository or install a local server.

Example prompt: *“Find the official React documentation for cleaning up a useEffect. Use the relevant version and cite its source.”*

See Client integrations, Getting started, or Account-free evaluation for complete setup instructions.

Use Docsy in ChatGPT

[Open the Docsy ChatGPT plugin](https://chatgpt.com/plugins/plugin_asdk_app_6ad6814ca7708191956117b3a3b58eb5).

This is the publisher-provided ChatGPT plugin link. Availability and sign-in depend on your ChatGPT account and client. This publisher link is not evidence of official ChatGPT marketplace approval. The SDK and CLI are available separately at https://github.com/getremcp/docsy.

Connect your AI client

Two separate hosted MCP endpoints serve different use cases:

Both expose the five read-only tools. The public endpoint does not make private libraries, account data or arbitrary web URLs accessible. On 31 October 2026, anonymous initialize, tools/list, resolve-library-id and query-docs passed a live MCP protocol smoke test; the canonical endpoint still returned HTTP 401 without OAuth. This is not a claim of a completed Codex CLI agent test.

Claude Code — canonical OAuth endpoint

claude mcp add --transport http docsy https://docsy.remcp.site/mcp/registry

Codex CLI — canonical OAuth endpoint

codex mcp add docsy --url https://docsy.remcp.site/mcp/registry

codex mcp login docsy

Cursor, VS Code and other remote MCP clients — configure a Streamable HTTP connection to the canonical URL:

{

"mcpServers": { "docsy": { "type": "http", "url": "https://docsy.remcp.site/mcp/registry" } } }

For account-free evaluation and protocol-level commands, see Public MCP evaluation. Some clients initiate OAuth discovery on their own even for an anonymous endpoint; client-specific behavior must be verified separately.

Where Docsy is published

Docsy is available through official registry records, npm, GitHub, independent directories, and client configuration. Being listed in a community directory does not mean approved by the official ChatGPT, Anthropic, Cursor, or Codex marketplace.
