Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 184 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name perfect-brief.

  • Pass
    Lists tools

    tools/list returned 7 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 187 ms over 2 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 189 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.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Fail
    Parameters documented

    0 of 10 parameters have a description (0%). The bar is 80%.

  • Pass
    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.

  • Pass
    Source repo linked

    A 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

Capabilities

Tools 7

aggregate_verdicts

Turn your model's verdicts into the bar's score, gate and decision. Advisory. Validates the verdicts against the live ruleset (every rule exactly once, valid status and confidence, the version you judged at) and against the brief (each quote must be copied verbatim), then aggregates them with the same engine that scores on the service: same verdicts, same number. Any error means no score — fix and resend. The result is tagged evaluation_source "client" and authoritative false: your model wrote the verdicts, so it is advice, never a welance score, and it cannot authorise publication on the welance/directory (the directory scores every brief itself). Say so when you report it. Fix gate.missing first. directory_context false drops the directory-only policy rules.

Discovered
bar_status

Which ruleset version is live, and what this free surface can do. Confirms the mode (bring your own model, zero provider calls, no fallback to welance's model) and the tools available.

Discovered
check_brief

Deterministic checks only — semantic coverage is INCOMPLETE. Never a score. Finds what a pattern can find for certain: emails, URLs and phone numbers (which block anonymisation), a stated budget and timeline, personal-data cues without a compliance cue, unfilled placeholders, the title line and labelled sections. It does not judge meaning: company or person names, a vague problem or an unmeasurable goal pass straight through. Use it as a quick pre-flight, then judge with get_judge_prompt and aggregate_verdicts.

Discovered
get_brief_template

A brief template built from the live rules, with the inputs each section needs. Use it to start a brief from nothing, or to see which section a gap belongs in. Markdown, one section per rule, gate rules marked; write in any language.

Discovered
get_improvement_prompt

A working order for improving a brief with your own model, gate first. Pass the verdicts you already have (the JSON array from your model) to target the failing rules in weight order; without them the prompt walks every rule. The prompt keeps the author's voice and forbids invented scores and facts. Nothing is generated here: your model does the writing.

Discovered
get_judge_prompt

The judge prompt and verdict JSON Schema, for YOUR model to answer. Free. This is the service judge's own prompt, word for word, so your model grades against the same bar. Pass the brief to get it embedded, or leave it empty for a template with a {{BRIEF}} placeholder. Answer the prompt with your own model (temperature 0 if you can), return only the JSON array it asks for, and send that array with the brief and the returned ruleset_version to aggregate_verdicts. welance runs no model for this.

Discovered
get_rules

Read the bar before judging anything. Free; no model runs. Returns the live catalogue with its version: every rule's id, title, criteria (what the judge reads), weight, gate role, policy context and how to pass it, plus the arithmetic — status scores, confidence threshold, accept threshold, bands, the gate and which policy contexts can be turned off. The number of rules is whatever the live catalogue says.
