Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 186 ms.

  • Fail
    Valid handshake

    initialize did not return a supported protocolVersion and serverInfo.name.

  • Pass
    Lists tools

    tools/list returned 17 tools.

  • Pass
    Current protocol

    Negotiated 2026-07-28. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 186 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 186 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.

  • Fail
    Parameters documented

    12 of 35 parameters have a description (34%). 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 2026-10-31T13:16:29.736541Z, within 180 days.

Capabilities

Tools 17

agent_capabilities

Return the tools, scopes, cost table and data coverage available to this session.

Discovered
analytics_config_delete

Delete one saved analytics config draft owned by the user.

Discovered
analytics_config_list

List the user's saved Outcome Lab config drafts, optionally for one report.

Discovered
analytics_config_save

Save a named analytics config draft. Pass config_id to update an existing draft; omit it to create a new one. Saving is free and does not create a snapshot.

Discovered
analytics_fast_verify

Run the free fast verification over the first 200 matches. It returns a snapshot and never saves an analysis or charges tokens.

Discovered
analytics_quote

Validate a spec and return the runtime token price, cohort estimate, work units and offer_id. Quotes do not spend tokens.

Discovered
analytics_report

Return one search report, its default analytics spec, ready question configs, suggestions and the estimated cohort. Use report.defaults.spec as the starting config.

Discovered
analytics_run

Run and save a full Outcome Lab analysis from a quoted spec. This spends tokens; call analytics_quote first and pass its offer_id.

Discovered
analytics_schema

Return the analytics metric catalogue, dimensions, curated questions, pricing tiers and fast-verification limit. Start here before building a config.

Discovered
catalog_list

List the authenticated user's saved patterns (public fields only).

Discovered
catalog_save

Save a pattern sketch to the user's library. Requires the catalog:write scope, which the user must grant at approval time.

Discovered
list_coins

List coins with trading statistics (signal strength, spread, win probability).

Discovered
market_klines

Fetch OHLC klines for one symbol and interval.

Discovered
quota_status

Return the account's remaining tokens so the agent can plan before spending.

Discovered
search_result

Return one page of a completed search's per-coin matches plus a report_url link to the full human-readable report. Heavy per-candle series are omitted unless include_series is true.

Discovered
search_status

Report whether a submitted search is running or complete. A completed search carries its match count and a report_url link to the full human-readable report.

Discovered
search_submit

Submit a chart-pattern search. Returns a task id immediately; poll search_status/search_result. Idempotent per request within a session only by the caller's own retry discipline.
