Docsy
Enables version-aware lookup of official React documentation, returning focused excerpts and links to the original source pages for topics such as useEffect cleanup.
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
Tool | Use it for |
| Match a framework, package or SDK name to its documentation ID |
| Discover available versions and indexed status |
| Get focused excerpts or source links for a chosen library/version |
| Search the public documentation index |
| Read a returned result by ID or a verified publisher page |
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.
Client | Fastest path |
ChatGPT | Open the publisher-provided Docsy plugin link (availability depends on your account) |
Claude Code |
|
Codex CLI |
|
Cursor / VS Code | Add a Streamable HTTP MCP server pointing to |
Any MCP-compatible client | Use the OAuth 2.1 endpoint |
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.
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:
Endpoint | Access | Purpose |
| OAuth 2.1 | Canonical account-linked MCP connection |
| No Docsy account or API key | Rate-limited evaluation against public documentation |
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

}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.

Releases, scope and security
This repository is the public integration and distribution package, not the hosted Docsy backend. It intentionally includes plugin manifests, client settings, read-only skill metadata, reviewed documentation and brand assets; it does not include crawlers, database contents, deployment secrets or a local server implementation.
Use the stable GitHub release for downloadable plugin assets; don't assume prereleases are approved marketplace versions.
The canonical endpoint uses OAuth 2.1; the public evaluator has its own rate limits and public-corpus boundaries.
Never include credentials, personal information or proprietary code in documentation queries or public security reports.
For a vulnerability or potential exposure, follow SECURITY.md, not a public issue containing sensitive details.
