Performance

  • Not measured
    Fast (p50)

    Median latency 66 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 66 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

    Every tool description is at least 20 characters.

    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Fail
    Website matches publisher

    The website host does not match the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass

about

Free. What Readmd does, prices of the paid tools and HTTP endpoints, and links to docs.

Discovered
preview_url

Free. Fetches a URL and returns its title, metadata, outline, word and token counts and the first 500 characters of the clean Markdown. Use read_url (paid, $0.001) for the full text.

Discovered
read_url

Read a web page as clean Markdown for an LLM. Fetches the URL (robots.txt respected), extracts the main content (drops navigation, headers, footers, sidebars, cookie banners) and returns GitHub-flavoured Markdown with headings, lists, tables, code blocks (with language) and absolute links, plus metadata (title, description, author, published/modified dates, site name, language, canonical URL, image), an outline of headings, word count and a token estimate. Options: mode=full for the whole page, links=false to save tokens, images=true, include_links=true for the link list, max_tokens to truncate, chunk_tokens to get RAG-ready chunks with heading paths. Also converts native Markdown, plain text, JSON and RSS/Atom feeds. Never charged when it fails: unreachable or 4xx/5xx targets, robots.txt disallow, unsupported types (PDF, images) and empty/JavaScript-only pages return an error and are not settled. $0.001 per page. Costs $0.001 USDC per call via x402 (charged only on success). Without an x402 wallet you get the payment terms and the paid HTTP URL instead.

Discovered
read_urls

Read up to 10 web pages as clean Markdown in one call, in parallel: the same output as /v1/read for each URL, with a per-URL ok/error. $0.005 per call (= $0.0005 per page at 10 URLs). Charged only if at least one URL is read successfully. Costs $0.005 USDC per call via x402 (charged only on success). Without an x402 wallet you get the payment terms and the paid HTTP URL instead.
