## Tools

15 declared. Statically extracted from the shipped source — a floor on the surface, not a census.
- `agent_pay` — Send tokens from the agent vault to a recipient, signed by the agent as the on-chain delegate. Every
- `agent_wallet_status` — Show an agent wallet as it actually stands on-chain: vault balance, how much of the delegated allowance is
- `approve_agent_allowance` — Set how much the agent may spend from the vault, enforced by the SPL Token program. This REPLACES the
- `create_agent_wallet` — Create an agent wallet on Solana. Generates a fresh keypair for the agent, creates a vault token account
- `deploy_agent_onchain` — Mint the agent an on-chain identity in the Metaplex Agent Registry on Solana, carrying its EIP-8004
- `export_agent_runtime` — Produce the config that puts this agent wallet in front of a model: an mcp.json block, the equivalent
- `fund_agent_wallet` — Move tokens from your wallet into the agent vault, and optionally send the agent a little SOL for its own

- `spend_log` — The audit trail for one agent: every spend that went through and every one the guardrails refused, with the
- `withdraw_from_vault` — Withdraw tokens from an agent vault back to your own wallet. The vault is yours, so this always works,

**Cautions** (coverage gaps and advisories — never blocking)
- No publisher has proved control of this listing; it is indexed, not vouched for.
**Client configuration withheld.** Client configs are withheld because this entry has a blocking finding. Show the warnings below to the person installing it.

## 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.
