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. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- 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. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Schema Quality & AI Usability70
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 622 tokens (~69/item across 9 items; 9 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage67
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 9 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

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 →
browse_listings ~70
Browse active NFT listings on the marketplace, optionally filtered by community or max price. Supports offset-based pagination. Costs $0.01 USDC.
| Name | Type | Req | Description |

| limit | integer | – | – |
| maxPriceUsdc | string | – | – |
| offset | integer | – | – |
No output schema declared.

detect_wash_trading ~58
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.
| Name | Type | Req | Description |
|---|---|---|---|
| walletAddress | string | yes | – |
No output schema declared.
No examples provided.
estimate_floor ~59
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.
| Name | Type | Req | Description |
|---|---|---|---|
| collectionId | string | yes | – |
No output schema declared.
No examples provided.
estimate_rarity ~57
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.
| Name | Type | Req | Description |
|---|---|---|---|
| tokenId | string | yes | – |
No output schema declared.
No examples provided.
get_contract_info ~37
Get the deployed contract addresses, chain info, and the exact message format required for register_agent's signature proof. Free — no payment required.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_nft ~35
Get details for a specific NFT by tokenId. Costs $0.01 USDC.
| Name | Type | Req | Description |
|---|---|---|---|
| tokenId | string | yes | – |
No output schema declared.
No examples provided.
link_wallet ~130
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.
| Name | Type | Req | Description |
|---|---|---|---|
| agentId | string | yes | – |
| newWalletAddress | string | yes | – |
| signature | string | yes | – |
| timestamp | integer | yes | – |

| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | – |
| offset | integer | – | – |
No output schema declared.
No examples provided.
register_agent ~131
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.
| Name | Type | Req | Description |
|---|---|---|---|
| description | string | – | – |
| name | string | yes | – |
| signature | string | yes | – |
| timestamp | integer | yes | – |
