- hygiene: 80
- liveness: 98
- freshness: 100

- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 93/100 (strong)

### protocol: n/a (weight 25)

- n/a `protocol.modern`, `protocol.stateless`, `protocol.transport`, `protocol.list_ttl`: no remote answered a protocol handshake (not probed yet, unreachable, or local-only)

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 93 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 1 tools have descriptions over 1,024 characters, which crowds the context
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 1 of 1 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 552 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history not recorded yet

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 1, about 552 tokens to load them all
- badge: [![protogrid quality](https://protogrid.dev/badge/net.fidren/counterparty.svg)](https://protogrid.dev/servers/net.fidren/counterparty)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (1)

- `fidren_check_counterparty`: Before an AI agent pays an unfamiliar counterparty, Fidren returns what payment action the observed evidence supports, how much exposure that evidence supports for the amount actually requested, and why.

Same counterparty, same evidence, a different requested amount: potentially a different payment action. The amount is an input to the decision, not a filter applied to a fixed score.

Call this before sending a payment to a counterparty address the agent has not paid before. Or before raising the amount it is willing to send to a counterparty it has paid before. Or when a counterparty requests more than a previously approved exposure.

Cost: 100 free decisions per day, per IP. None. No account, no API key, no card, no wallet. After that, $0.01 USDC per decision over x402 on eip155:8453.

Coverage: observed settlement history is indexed on base (eip155:8453) only. An address on any other chain answers from no history rather than from evidence — which is a statement about coverage, not a verdict about the counterparty.

Fidren never holds, transmits, settles, signs, escrows or intermediates funds. It returns an advisory decision; the caller’s own infrastructure enforces it. A returned verdict is advice; it moves nothing and blocks nothing on its own.
