DAP Foundry missed 2 checks this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

compute

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.

convert

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.

decode

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.

diff

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.

DAP Foundry — questions

Answers built from our own checks of this server.

What can DAP Foundry do?

It exposes 4 tools, read directly from the server on our last check. Among them: compute-day-count-to-settlement, convert-unix-timestamp-to-date, decode-base64-to-text, diff-two-line-lists. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is DAP Foundry working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 150 ms. The bar chart above shows every period we have measured.

How do I connect DAP Foundry?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does DAP Foundry need an API key?

No. DAP Foundry completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is DAP Foundry?

It answers our handshake in 150 ms on average, which is faster than 82% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
