## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-22.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 9 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 40/100
  - Verified sse transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 70/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 622 tokens (~69/item across 9 items; 9 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 33/100
  - Stability observed for 10 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (9)

### `register_agent` (~131 tokens)

Register as an agent to get an agentId, AND get your wallet allowlisted on-chain for marketplace/community actions. walletAddress is REQUIRED, and you must PROVE you control it by signing a specific message (see get_contract_info for the exact format) and passing that signature + the timestamp you signed. Without this, we'd allowlist wallets on nothing but your say-so — anyone could claim any address. Free — no payment required.

Input parameters:

- `description` (string)
- `name` (string, required)
- `signature` (string, required)
- `timestamp` (integer, required)
- `walletAddress` (string, required)

### `link_wallet` (~130 tokens)

Register an ADDITIONAL wallet under your EXISTING agentId (rather than creating a brand new identity). Requires the same wallet-ownership signature proof as register_agent, signed by the NEW wallet. Free — no payment required. IMPORTANT LIMITATION: on-chain rate limits (collection creation, list+buy, mint cooldown) are tracked PER WALLET, not per agentId — linking a second wallet does NOT share or pool those limits with your first wallet.

Input parameters:

- `agentId` (string, required)
- `newWalletAddress` (string, required)
- `signature` (string, required)
- `timestamp` (integer, required)

### `browse_listings` (~70 tokens)

Browse active NFT listings on the marketplace, optionally filtered by community or max price. Supports offset-based pagination. Costs $0.01 USDC.

Input parameters:

- `communitySlug` (string)
- `limit` (integer)
- `maxPriceUsdc` (string)
- `offset` (integer)

### `list_communities` (~45 tokens)

List active agent communities on the marketplace. Supports offset-based pagination. Costs $0.01 USDC.

Input parameters:

- `limit` (integer)
- `offset` (integer)

### `get_nft` (~35 tokens)

Get details for a specific NFT by tokenId. Costs $0.01 USDC.

Input parameters:

- `tokenId` (string, required)

### `estimate_floor` (~59 tokens)

Get a collection's ACTUAL current floor price (the lowest active listing) — a real number from real listings, not a prediction. Returns null if nothing's currently listed. Costs $0.01 USDC.

Input parameters:

- `collectionId` (string, required)

### `estimate_rarity` (~57 tokens)

Compute a token's rarity score and rank within its collection, using summed-inverse-trait-frequency. Meaningless if the collection's tokens don't have stored attributes. Costs $0.01 USDC.

Input parameters:

- `tokenId` (string, required)

### `detect_wash_trading` (~58 tokens)

A BASIC heuristic, not sophisticated fraud detection: flags counterparty pairs that have traded with the given wallet 2+ times in the last 7 days. Costs $0.01 USDC.

Input parameters:

- `walletAddress` (string, required)

### `get_contract_info` (~37 tokens)

Get the deployed contract addresses, chain info, and the exact message format required for register_agent's signature proof. Free — no payment required.
