## 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 2026-11-05.

- **Endpoint Security**: 80/100
  - 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.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 60/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 775 tokens (~193/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 17/100
  - Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 87/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 60% 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 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-05 (score 72, +1)

- [security] The server rewrote its instructions, which are the text every model session reads
- [security] Tool “compute-day-count-to-settlement” rewrote its description, which is the text the model reads
- [security] Tool “convert-unix-timestamp-to-date” rewrote its description, which is the text the model reads

### 2026-11-04 (score 71, +1)

No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-11-02 (score 70, +1)

- [security] The server rewrote its instructions, which are the text every model session reads

## MCP tools (4)

### `compute-day-count-to-settlement` (~168 tokens)

Compute day count to settlement

Use when you need a Canadian settlement date or accrual fraction. Rolls a trade date forward on the Payments Canada calendar and counts the accrual under ACT/360, ACT/365F, 30/360, 30E/360 or ACT/ACT-ISDA. $0.01 USDC on Base per answer via x402; a refusal is free.

Input parameters:

- `accrual_start` (string, required): a real calendar date, the first day of the accrual period, counted
- `acknowledge` (string, required)
- `calendar` (string, required)
- `convention` (string, required)
- `freshness_tolerance` (string, required): at most the ratified ceiling
- `settlement_lag` (required)
- `trade_date` (string, required): a business day on the calendar

### `convert-unix-timestamp-to-date` (~138 tokens)

Convert Unix timestamp to date

Use when you need Unix timestamps as dates. Converts one or more timestamps, seconds or milliseconds, one per line, to UTC dates in ISO 8601 as a CSV. $0.01 USDC on Base per answer via x402; a refusal is free.

Input parameters:

- `text` (string, required): One or more Unix timestamps, one per line: whole seconds or milliseconds, digits with an optional leading minus, inside the years 0001 to 9999. At most 1,048,576 bytes of UTF-8 and 10,000 lines; a li…

### `decode-base64-to-text` (~184 tokens)

Decode base64 to text

Use when you need to read base64 as text. Decodes standard base64 to UTF-8 text and refuses anything that is not valid base64 or not valid UTF-8, rather than guess. $0.01 USDC on Base per answer via x402; a refusal is free.

Input parameters:

- `text` (string, required): Base64 that decodes to UTF-8 text: the letters A to Z and a to z, the digits 0 to 9, + and /, then one or two = of padding at the end, which may be left out but, when given, must make the length a mu…

### `diff-two-line-lists` (~131 tokens)

Diff two line lists

Use when you need to compare two lists of lines. Marks each distinct line only_a, only_b or both, matched exactly as sent, as a CSV. $0.01 USDC on Base per answer via x402; a refusal is free.

Input parameters:

- `text` (string, required): Two lists of lines: a line ---A---, then list A, then a line ---B---, then list B, one item per line. At most 1,048,576 bytes of UTF-8 and 50,000 lines; a line break at the very end is not a line.

## Common questions

### What is the DAP Foundry MCP server?

DAP Foundry is an MCP server listed in the public MCP registry as solutions.dap/foundry. Tools that refuse rather than guess: settlement day counts, Unix timestamps, base64, line diffs. This page covers its hosted endpoint (https://foundry.dap.solutions/mcp).

### Is the DAP Foundry MCP server safe to use?

DAP Foundry scores 72 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the DAP Foundry MCP server expose?

DAP Foundry exposes 4 tools: compute-day-count-to-settlement, convert-unix-timestamp-to-date, decode-base64-to-text, diff-two-line-lists. Their descriptions and schemas cost roughly 621 tokens of context every time the server is loaded.

### Does the DAP Foundry MCP server require authentication?

No. We connected to DAP Foundry without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the DAP Foundry MCP server still maintained?

DAP Foundry is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
