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 Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability58
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 3777 tokens (~343/item across 11 items; 11 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 Management100
- No destabilizing schema changes in the last 30 days.Pass
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
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 11 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 12 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 →
assetfare_manifest ~52
Read the Ed25519-signed release manifest and safety-bundle binding before preparing an action. Example: call this once to verify the current release and contract pins; it never creates state, signs, or submits.
Input schema present but exposes no named parameters.

No examples provided.
assetfare_v2_capabilities ~125
Read the 65 curated public routes, live provider readiness, whole-route product classification, direct_route_summary, and continuation_v3 contracts before quoting. The offered routes comprise 3 core, 50 conditional, and 12 strategic/scarce routes; 35 additional researched routes are not public products. Example: call once before requesting an exact route quote, then confirm the fresh quote. Route classification never adds an execution gate. continuation_v3 separately binds execution selection, wallets, bounds, and mode. Read-only; creates no wallet login, session, or action.
Input schema present but exposes no named parameters.

assetfare_v2_prepare ~506
Return one deeply verified first unsigned bundle and caller-wallet handoff. Example: pass caller_approved=true, a one_shot approval_v3, and the quote-bound verification_context; multi-step routes reject one_shot. Economic guidance is advisory and adds no request field. Context is validated before the upstream request and never forwarded. AssetFare never signs or submits.
| Name | Type | Req | Description |
|---|---|---|---|
| amount_usd | number | yes | Requested input value in USD, minimum 1. USD 1 is reachability/schema smoke only. A USD 50 competitive bucket was observed only for dated 2026-09-23 Solana USDC to Base USDC evidence and must not be… |
| approval_v3 | object | yes | Strict one-shot approval copied from the exact unexpired selected quote; its bounds may only be strengthened. |
| caller_approved | boolean | yes | Legacy caller assertion that MUST be supplied explicitly. It is not human-proof and is never auto-inserted; approval_v3 adds server-enforced quote binding. |
| event_signer_public | – | – | Solana CCTP only: caller-generated ephemeral public key. Keep the matching private key client-side and use it to co-sign the returned unsigned event-account transaction; never send the private key. |
| from_chain | string | yes | Source chain for the v2 route. Polygon, Optimism, Ethereum, HyperEVM, X Layer, Sei, Sonic, Monad, Avalanche, Cronos, Injective, Linea, Aptos, Unichain, and Ink are source-only and cannot be used as t… |
| from_token | string | yes | Input token symbol on from_chain. The chain-token pair must appear in current v2 capabilities. |
| to_chain | string | yes | Destination chain for the v2 route: Solana, Base, Arbitrum, or Robinhood Chain. Source-only chains are not destinations. |
| to_token | string | yes | Output token symbol on to_chain. The chain-token pair must appear in current v2 capabilities. |
| verification_context | object | yes | Strict caller-held one-shot context copied from the selected quote, approval and public wallets. It is verified before prepare and never forwarded upstream. |
| wallets | object | yes | Map each chain needed by this route to the caller's public wallet address. Include public addresses only; never private keys or seed phrases. |
| Name | Type | Req | Description |
|---|---|---|---|
| action_verification | object | yes | Fail-closed semantic and approval-bound verification result; it never authorizes a signature by itself. |
| bundle | object | yes | Exact Core bundle whose payload_sha256 remains scoped only to this nested object. |
| caller_wallet_handoff | object | yes | Fresh self-verifying EIP-1193 or Solana Wallet Standard handoff. The caller still simulates, confirms, signs and submits. |
| local_execution_gate | object | yes | Remote verification is not signing authority. Recompute locally and require verified_for_signing after fresh wallet simulation. |
| semantic_verification | boolean | yes | True only after full decoded action, intent, receipt, payload and caller-bound verification. |
No examples provided.
assetfare_v2_quote ~353
Get one fresh AssetFare quote with amount-specific economic_guidance, direct_route_summary, continuation_v3, and unsigned_prepare_requirements. Example: quote Solana USDC to Base USDC. price_recommended_for_amount is advisory; compare alternatives when price matters, but no economic acknowledgement field is required. The quote remains an unranked_candidate until separate explicit approval selects one mode. The adapter validates hashes, path, bounds, and TTL and never creates approval, prepares, signs, or submits.
| Name | Type | Req | Description |

assetfare_v2_quote_selected_candidate ~462
Reuse the chosen exact request-time quote while valid; after expiry refresh only that candidate at the same amount and never reselect. Example: pass candidate_id and the selection receipt hash. An AssetFare result requires a caller-local proof check and fresh wallet simulation before verified_for_signing; remote verification is not signing authority. An external result is only its provider handoff and has no AssetFare transaction-verification claim. Never prepares, signs, submits, or grants transaction authority.

| from_token | string | yes | Input token symbol on from_chain. The chain-token pair must appear in current v2 capabilities. |
| max_eta_seconds | integer | – | Optional stricter maximum ETA in seconds; it cannot exceed 60 or the selected profile limit. |
| profile | string | – | Time policy: fast (30s), balanced (60s default), or explicit economy (60s). Every recommendation profile has an absolute 60-second ceiling. |
| selection_receipt_sha256 | string | yes | Exact selection_receipt.sha256 returned with the fresh shortlist. |

assetfare_v2_route_selection ~442
Quote the recent top two plus the best AssetFare graph at the exact amount; return up to two all-in choices labeled assetfare_verified_unsigned or external_provider_handoff. AssetFare cost, ETA and rank are always present; a recent winning range needs two supporting higher buckets and disappears on conflict. Example: compare Solana USDC to Base USDC at USD 347.25 with balanced (60s). Fast is 30s; balanced and explicit economy are 60s. The 60-second ceiling is absolute for recommendations; slower routes are reference-only. Never approves, prepares, signs, or submits.
