Common questions
Is Refdocs safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 5 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js, Docker on your computer.
What can I use instead?

README from the maker
Open the README
Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.
refdocs
refdocs answers documentation questions and turns web pages into something an agent can actually read. Search runs across public technical documentation and GitHub for the facts or code snippet behind a question, and any URL can be fetched and handed back as clean markdown instead of raw HTML.
It is one small program with two faces: a command-line tool for quick lookups, and a stdio MCP server that gives agents the same two operations as tools.
Configuration
Both operations require a Ref API key:
export REF_API_KEY="your-key-here"The search endpoint defaults to https://api.ref.tools. Override it with REF_API_BASE_URL when you are pointing at another deployment. The key is checked before any request is made; when it is missing the tool fails with an error that names REF_API_KEY.
Install
npx @reneturcios/refdocs search "How do I stream a response with fetch?"Or run the container image:
docker run -i -e REF_API_KEY ghcr.io/cloudcorprecords/refdocsThe container defaults to the MCP server (see below). Pass CLI arguments to use it as a CLI instead.
CLI
# Search the documentationrefdocs search "How do I use the cache API in Next.js?" refdocs search "What does this error mean?" --json
Read a page as markdown
refdocs read https://example.test/some/guide refdocs read https://example.test/some/guide --json
Check the configuration without making a request
refdocs check
refdocs --version
Exit codes: 0 on success, 1 when a lookup fails or the configuration is not ready (the error names the problem), 2 for usage errors.
MCP server
One bin serves both faces. The mcp subcommand starts a stdio MCP server:
npx -y @reneturcios/refdocs mcpMCP client configuration:
{"mcpServers": { "refdocs": { "command": "npx", "args": ["-y", "@reneturcios/refdocs", "mcp"], "env": { "REF_API_KEY": "your-key-here" } } } }
Tools
| Tool | Input | What it returns |
|---|---|---|
ref_search_documentation | query (string, required) — a full sentence or question to search for | Matching documentation results from public documentation and GitHub, each with its title, URL, and content or snippet when the upstream provides them. |
ref_read_url | url (string, required) — the URL of the webpage to read | The page content converted to markdown: headings, links, lists, emphasis, and code blocks are kept in markdown form, while scripts, styles, and other non-content markup are dropped. |
Search responses are parsed tolerantly: a bare array, a results list, and a documents list are all accepted. Reading plain-text URLs returns the text unchanged.
Development
npm installnpm run build # tsc -> dist/ npm test # node test runner over test/*.test.ts, no network npm run dev # run the CLI from source via tsx
Tests run entirely against a fake fetch function; no live API calls are made.
