## Tools

13 declared. Statically extracted from the shipped source — a floor on the surface, not a census.
- `arc_quote` — Ask what a URL costs without paying. Returns price in USDC, seller address, network, whether the seller batches via Circle Gateway, the rail that would be used,
- `arc_pay` — Fetches the URL. If the server answers 402, CRA AGENT checks the spending policy, verifies the seller, signs a gas-free nanopayment through Circle Gateway (or a
- `arc_balance` — USDC in the wallet and in the Circle Gateway balance used for nanopayments, on the configured Arc network.
- `arc_deposit` — Moves USDC from the wallet into the Circle Gateway balance so nanopayments can be signed. On-chain transaction (needs a little USDC for gas on Arc).
- `arc_ledger` — The last N payment attempts by this agent with amount, seller, status, latency and transaction, plus today's spend.
- `arc_proof` — Gateway settles in batches, so the transfer to the seller reaches the chain after the response. This matches settled payments in the ledger to the on-chain USDC
- `arc_verify_receipt` — Verifies a receipt another agent hands over: recovers who signed it, checks it is the agent named inside, and redoes the arithmetic to confirm the payment fitte
- `arc_policy` — The limits this rail enforces for the agent. Read-only: limits are set by the operator in the environment, not by the model.
- `arc_job_create` — For work that is too large or too slow for a per-call payment. Creates a job with a provider (seller) and an evaluator; the provider then sets the budget, you f
- `arc_job_fund` — Moves the job's budget (set by the provider) from the agent wallet into the escrow contract. The spending policy is applied to the budget as one payment, with t
- `arc_job_status` — Client, provider, evaluator, budget, expiry and state (Open, Funded, Submitted, Completed, Rejected, Expired).
- `arc_job_decide` — As the job's evaluator: complete releases the escrow to the provider, reject returns it to the client. The reason is stored on-chain as a hash.
- `arc_job_submit` — As the job's provider: submits the keccak256 hash of the deliverable and moves the job to Submitted.

## Install

**Verdict: review** — Installable, but 1 thing to check first: No publisher has proved control of this listing; it is indexed, not vouched for.
**Cautions** (coverage gaps and advisories — never blocking)
- No publisher has proved control of this listing; it is indexed, not vouched for.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"mcp\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"@cra-agent/mcp\"\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.
