How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security81
- No malware found by supply-chain analysis.Pass
- CVE check failed: a known high-severity CVE affects zod 3.25.76, a direct dependency. A fixed version is available. View diagnostics → Fail
- No install/post-install scripts declared.Pass
- 30 of 110 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency48
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 65 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability79
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 670 tokens (~134/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management70
- Stability observed for 21 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "pay_x402" implies "pay" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
check_agent_status ~50
Check whether an address is registered and active on the 8004Swap Registry (i.e. allowed to trade). Read-only, no signing.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | EVM address to check |
No output schema declared.
No examples provided.
fill_quote ~127
Act as taker: settle a signed quote on-chain by calling Settlement.fillQuote (or fillQuoteWithPermit if a permit is supplied). Requires AGENT_PRIVATE_KEY, and the taker must already hold + have approved takerToken unless using a permit. Broadcasts a real transaction. Get `quote` from a prior request_quote call.
| Name | Type | Req | Description |
|---|---|---|---|
| permit | object | – | Optional EIP-2612 permit on takerToken, to skip a separate approve() tx |
| quote | object | yes | A WireQuote as returned by request_quote (one entry from its `quotes` array) |
No output schema declared.
No examples provided.
pay_x402 ~210
Fetches an HTTP resource; if it replies with the x402 payment-required protocol (protocol v2, github.com/coinbase/x402), signs an EIP-3009 authorization from the configured agent to satisfy it and retries, returning the final response. Only the 'exact' scheme with 'eip3009' transfer method is supported (rejects Permit2/ERC-7710 offers). Requires AGENT_PRIVATE_KEY. maxAmountAtomic bounds what this call may authorize; there is no other limit, so callers should always pass the smallest value that covers the expected price.
| Name | Type | Req | Description |
|---|---|---|---|
| body | string | – | Raw request body, if any |
| headers | object | – | Extra request headers |
| maxAmountAtomic | string | yes | Upper bound, in atomic units of the asset (e.g. USDC has 6 decimals), on what this call may authorize |
| method | string | – | HTTP method, default GET |
| url | string | yes | URL of the x402-gated resource |
No output schema declared.
No examples provided.
register_agent ~96
Self-register the configured agent (AGENT_PRIVATE_KEY) on the 8004Swap Registry so it's allowed to trade. One-time action per address; fails if already registered. Broadcasts a real (testnet) transaction.
| Name | Type | Req | Description |
|---|---|---|---|
| metadataURI | string | – | Optional metadata URI for this agent, defaults to empty string |
| ownerAddress | string | – | Address allowed to pause/manage this agent later; defaults to the agent's own address |
No output schema declared.
No examples provided.
request_quote ~187
Act as taker: broadcast an RFQ over the 8004Swap Relay and collect signed quotes from maker agents subscribed to this pair. Requires AGENT_PRIVATE_KEY (used to authenticate to the Relay, no gas spent). Resolves after the Relay's collection window closes (a few seconds) with quotes ranked best-first.
| Name | Type | Req | Description |
|---|---|---|---|
| expiresInMs | number | – | Requested RFQ window; Relay caps it at 30000ms regardless |
| makerToken | string | yes | ERC-20 address the taker wants to receive |
| minMakerAmount | string | – | Reject quotes offering less than this (smallest unit), default 0 |
| takerAmount | string | yes | Amount of takerToken offered, in the token's smallest unit (wei-equivalent), as a decimal string |
| takerToken | string | yes | ERC-20 address the taker is paying with |
No output schema declared.
No examples provided.
