### Description (declared)

# roost-mcp

Two zero-config, advisory MCP servers from [Roost](https://roostcapital.ai) for AI agents that handle money. No API key, no signup — an anonymous per-install token is created on first use. Calls are anonymized (hashed identifiers, bucketed amounts, no PII) and aggregated into a benchmark of money-moving-agent behavior; that's why they're free.

Install:

```
pip install roost-mcp
```

This provides two commands.

## Add it to your MCP client

Both servers run over stdio. Point your client at whichever you want (either works alone) — a Claude Desktop–style config:

```json
{
  "mcpServers": {
    "roost-corpus": { "command": "roost-corpus-mcp" },
    "roost-eval": { "command": "roost-eval-mcp" }
  }
}
```

If your client doesn't inherit your shell `PATH`, use the absolute path to the console script (what `which roost-corpus-mcp` prints).

## `roost-corpus-mcp` — payment pre-flight check

A second opinion before your agent sends a payment. The `check_payment` tool takes an invoice, purchase order, or transfer and returns a clear recommendation — **proceed**, **hold & review**, or **consider financing** — with the reasons: a suspected duplicate, an amount out of line with this agent's own history, an early-pay discount worth capturing, or terms worth using.

Advisory, not a gate — your agent stays in control. Fast, deterministic checks that sharpen as your agent builds a short history. USD invoices, purchase orders, and transfers today.

## `roost-eval-mcp` — finance-agent safety test

Find the money decisions your agent gets dangerously wrong — before it ships. `list_eval_scenarios` returns realistic money-action situations (fraud bait, payee changes, overspend, duplicate/replay, social engineering, …); your agent decides proceed/hold/flag on each; `submit_eval` returns a private scorecard that leads with a clear `summary.status` (`balanced` / `unsafe` / `over_conservative` / `mixed`), then the component metrics (coverage, correctness, consistency, sever…
