Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 676 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name hefestoai.

  • 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 635 ms over 2 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 672 ms over 2 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    2 of 2 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Pass
    Stable tool list

    No tool was removed and no required parameter was added in the last 30 days.

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.

  • 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

    7 of 7 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.

  • Not measured
    Website matches publisher

    This namespace is not a reverse domain, so the website comparison does not apply.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Pass
    Repo owner matches

    The GitHub repository owner matches the namespace login.

  • Pass

Capabilities

Tools 4

analyze

Runs the open-source hefesto-ai engine (`hefesto analyze --no-config`, free tier) on the files you send to the hosted analyzer and returns its findings: rule id, severity, file, line, message and the SARIF hefestoFingerprint/v1 fingerprint (format "sarif" adds the full SARIF 2.1.0 log). Use it to check a file or snippet the user shares (for example "analyze this file") for security and quality issues before committing. Try it: {"code":"password = \"Sup3rS3cret!2026\""} returns a HARDCODED_SECRET finding. Minimum call: {"code": "<file contents>"}. Add path (e.g. "app/run.py") so the language comes from the extension; without path or language the language is inferred from the content, else python. For several files send files=[{"path", "content"}] instead. severity and format are optional. Covers Python, COBOL, the DevOps/IaC formats hefesto analyze routes, and TypeScript, JavaScript, Java, Go, Rust and C# through the multilang tree-sitter grammars (the first such request on a fresh server instance downloads the grammars and can take a few seconds longer). Limits: 20 files, 100 KB per file, 256 KB in total, 20 seconds, 10 requests per minute per IP, shared across server instances. No .hefesto.yaml is read. Files are deleted after the run; nothing is stored. For a whole repository, run `hefesto analyze .` locally.

Discovered
compare

Return a short static comparison of HefestoAI with one named tool. Use it when the user asks how HefestoAI differs from another scanner. No live lookup and no code is inspected. All arguments are optional: {} compares with sonarqube. Known values: sonarqube (the default when tool is omitted), snyk, github-advanced-security, semgrep, claude-code-security, coderabbit, qodo. Any other value is answered as sonarqube.

Discovered
install

Return install commands for the open-source package (pip install hefesto-ai, Python 3.11+). Use it when the user wants to run HefestoAI locally, in a pre-commit hook or on a whole repository. Does not install anything on the caller's machine. No parameters: call it with {}.

Discovered
pricing

Return current HefestoAI prices (Free $0, PRO $8/month per user, OMEGA $19/month). Use it when the user asks what HefestoAI costs. Static text. Does not look up or change a subscription. No parameters: call it with {}.
