## 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 2026-10-04.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 59/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 305 tokens (~305/item across 1 items; 1 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% 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 1 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 1 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 20/100
  - Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28.

## MCP tools (1)

### `calculate_bond_periodic` (~305 tokens)

Calculate Periodic Bond Price/Yield

Calculate price, yield, and accrued interest for Periodic bonds. Powered by the Standard Securities Calculation Methods - Fixed Income (https://api.sscmfi.com).

Input parameters:

- `callSchedule` (array): Optional. List of discrete call dates and prices. AI Hint: The engine will automatically calculate the Yield-to-Worst using this schedule.
- `couponRate` (number, required): Annual coupon rate as a percentage (e.g., 5.0 for 5%). Use 0 for zero coupon bonds.
- `givenType` (string, required): Are you providing the clean Price or the Yield to find the other?
- `givenValue` (number, required): The numeric value of the Price (e.g. 98.75) or Yield (as a percent e.g. 4.25).
- `maturityDate` (string, required): The date the principal is due. Required format: MM/DD/YYYY (e.g., 01/05/2030). AI: Must use leading zeros and 4-digit years. (Ensure this is in the future relative to settlement).
- `securityType` (string, required): Crucial for math accuracy. Treasury: Usually uses Actual/Actual. Corporate/Agency/Municipal: Usually uses 30/360. CD: Usually uses Actual/360.
- `settlementDate` (string): Optional. Defaults to today. The date the money actually changes hands. Required format: MM/DD/YYYY (e.g., 07/04/2025).
