## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-21.

- **Endpoint Security**: 66/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 13 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 77/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 1089 tokens (~83/item across 13 items; 13 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 60/100
  - Stability observed for 18 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 77/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 30% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 13 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 14 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (13)

### `canon_sites` (~24 tokens)

List canon sites

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

### `canon_search` (~94 tokens)

Search the canon

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.

Input parameters:

- `limit` (integer)
- `q` (string, required): Search phrase, e.g. "modified duration" or "option pool shuffle"
- `site` (string): Restrict to one site

### `canon_get_entry` (~53 tokens)

Get one canon entry

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

Input parameters:

- `id` (string, required): Entry id or slug, e.g. "modified-duration"
- `site` (string, required)

### `canon_changes` (~46 tokens)

What changed in the canon

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

Input parameters:

- `since` (string): ISO date; only events on or after this date

### `canon_list_formulas` (~35 tokens)

List formulas

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

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

Input parameters:

- `formula` (string, required)

### `canon_compute` (~85 tokens)

Compute with a receipt

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.

Input parameters:

- `formula` (string, required)
- `inputs` (object, required): Inputs keyed by name; see canon_describe_formula

- `receipt` (object, required): The receipt object returned by canon_compute

### `canon_batch` (~64 tokens)

Compute many formulas at once

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.

### `canon_entity` (~78 tokens)

Resolve a US issuer

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.

Input parameters:

- `authority` (string)
- `q` (string)

### `canon_contract` (~80 tokens)

Prediction-market contract, normalised

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.
