Docsy missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.

Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

docs

query-docs

Retrieve current, version-aware documentation and code examples from one Docsy library, or request source links only (response: links) without loading or indexing document bodies. Resolve the library ID first unless the exact ID is known. Keep each query to one concept and do not call this tool more than 3 times per question.

fetch

fetch

Fetch one indexed search result by stable ID, or fetch a verified publisher page via libraryId + url previously obtained from link-only query-docs. The URL must belong to the exact authorized source and version; no arbitrary web fetching.

library

list-library-versions

Default: representative version preview. Supply limit/offset to paginate individual stable GitHub release tags, including patch versions absent from the preview. Indexed docs and upstream tags are distinguished. Upstream tags may have no usable documentation.

resolve

resolve-library-id

Resolve a package or product name to a Docsy library ID. Call before query-docs unless an exact /org/project or /org/project/version ID is already known. The query is used only to rank likely libraries; do not include credentials, PII, proprietary code, or other confidential data.

search

Search all public indexed documentation and return stable IDs and absolute URLs.

Docsy — questions

Answers built from our own checks of this server.

What can Docsy do?

It exposes 5 tools, read directly from the server on our last check. Among them: fetch, list-library-versions, query-docs, resolve-library-id, search. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Docsy working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 208 ms. The bar chart above shows every period we have measured.

How do I connect Docsy?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.

How do you sign in to Docsy?

No API key is involved. Docsy answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.

How fast is Docsy?

It answers our handshake in 208 ms on average, which is faster than 69% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Docsy open source?

The code is open source: it is published under the MIT licence and 1 stars on GitHub. The licence covers the code in the repository, not the hosted service at docsy.remcp.site, which runs on its operator's own terms.
