Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 48 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name romankryvolapov-mcp.

  • Pass
    Lists tools

    tools/list returned 4 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 48 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 48 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.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    9 of 9 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches 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
    Recently updated

    Updated 2026-11-11T18:04:18.97035Z, within 180 days.

Capabilities

Tools 4

fetch

Return the full text of one article by the id from search results (its canonical URL), as markdown with code listings preserved verbatim.

Discovered
get_page

Return the full markdown of one article by its canonical URL (e.g. https://romankryvolapov.com/ru/ktor-manual/). Code listings are preserved verbatim. The same as fetch, as plain text.

Discovered
search

Search the romankryvolapov.com engineering blog: articles on Java, Kotlin, Android, Spring, microservices, gRPC, Kubernetes, databases, and running large language models locally (llama.cpp, LoRA fine-tuning, RAG, prompt engineering). Every article exists in English, Russian and Ukrainian, and results come in one language: set lang to the user’s language, otherwise it is guessed from the query. Returns matching articles with snippets and URLs; read one with fetch, passing its id.

Discovered
send_message

Send a message to Roman Kryvolapov, the author of this blog: a question about one of the articles, a suggestion for a new article, or a job or project offer. It goes to his inbox, and he replies by email to the address given. Use it only when the user asked to contact the author, with the user’s own name and email address — never invent them — and show the user the text before sending. At most 20 messages a day are accepted from all agents together, and 3 from one email address.
