# capacity-attest

MCP server for capacity-delivery attestations: after an x402 payment for compute capacity (GPU-hours, storage, API credits, bandwidth), the paying agent leaves a signed, factual claim of what was actually delivered, so other agents can check a seller's de

## Tools

3 declared. Statically extracted from the shipped source — a floor on the surface, not a census.
- `record_delivery` — Record a signed delivery claim after an x402 capacity settlement (gpu-hours, storage, api-credits, or bandwidth).
- `get_delivery_history` — Return every signature-verified delivery claim recorded against a given sellerAddress in THIS installation's
- `resolve_agent_identity` — Look up an agent's on-chain identity registration in an ERC-8004 Identity Registry: who owns the agentId

## Install

**Verdict: install** — No blocking findings and no open coverage gaps — safe to install as configured.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"capacity-attest\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"capacity-attest\"\n      ]\n    }\n  }\n}"
```

## Blast radius

Contained to moderate — no credential declaration found, from the publisher, the upstream registry, or the README. Known so far: runs on your machine; read-only tool surface.
- Floor 13, ceiling 31 (tier: unknown)
- `unknown` means the floor and ceiling land in different bands — not measured enough to name one. It does not mean low.
- This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score.
