Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 458 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name wallstreet-wiki-canon.

  • Pass
    Lists tools

    tools/list returned 13 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 458 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 458 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

    6 of 20 parameters have a description (30%). 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.

  • 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 2026-09-03T06:12:16.829995Z, within 180 days.

Capabilities

Tools 13

canon_batch

Run up to 50 computes in one call, for scenario grids and sensitivity tables. Each item returns its own receipt; the batch receipt id is sha256 over the sorted item receipt ids, so a whole table can be cited by one hash.

Discovered
canon_changes

Aggregated dated change events across every vertical, newest first. Poll this instead of re-crawling.

Discovered
canon_cite

Ready-to-paste citation strings (markdown, plain, apa, bibtex) for one entry, with the reviewed date. Use when writing a report that quotes the canon.

Discovered
canon_compute

Run one formula from the registry on validated inputs. Returns outputs, the convention used, citations, and a receipt whose id is sha256 over formula, version, canonical inputs and outputs. Invalid inputs return an explicit problem list and a working example instead of nulls.

Discovered
canon_contract

Fetch one Kalshi (ticker) or Polymarket (slug or condition id) contract and return rules text, close time, resolution source and status in one shape. For a paid cross-venue identity check with a snapshot receipt, call GET /v1/contracts/compare over REST.

Discovered
canon_describe_formula

Input schema with ranges and defaults, output names, stated convention, citations and test vectors for one formula.

Discovered
canon_entity

Map a ticker (AAPL, BRK.B), a CIK, or a company name to one issuer id with every ticker and exchange, plus EDGAR filing locations. Use before joining prices, filings and news so identifiers line up; source is the SEC public ticker file.

Discovered
canon_get_entry

Full definition and notes for one entry, by site and id (ids come from canon_search).

Discovered
canon_list_formulas

The deterministic formula registry: id, site, summary, input names and citations. Call canon_describe_formula for a schema.

Discovered
canon_search

Search defined terms and reference tables across all canon sites (options, fixed income, quants, PE, M&A, private credit, venture, hedge funds). Returns ranked hits with a citable url and the JSON source.

Discovered
canon_sites

The sites in the .wiki finance canon with live entry counts and review dates.

Discovered
canon_thresholds

Reference table of the regulatory figures agents get wrong: 13F, 13D and 13G, Form 4, Form PF tiers, adviser registration, 3(c)(1) and 3(c)(7), accredited investor, qualified client, Form D, CFTC 4.13(a)(3), ERISA 25 percent, AIFMD, HSR, Reg T. Each row carries the rule, authority, effective date, primary source and a confidence label. Filter by words or authority.

Discovered
canon_verify

Recompute a receipt from its inputs and confirm its id and outputs. Use it to check a number another agent or document claims came from this service.
