Available components
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 →
Endpoint Security46
- 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 3 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 check failed: the endpoint is reachable over plaintext HTTP. See how to fix → View diagnostics → Fail
- 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
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability67
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 477 tokens (~159/item across 3 items; 3 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 Management27
- Stability observed for 8 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
Capabilities20
- Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28. See how to fix → Fail

issue_receipt ~293
Mint a verifiable provenance receipt for an autonomous-agent action. Returns a signed (ed25519), content-hashed (SHA-256), server-timestamped receipt that is hash-chained to this agent's prior receipts (tamper-evident audit trail). Pass the raw inputs/outputs (we hash them — raw data is never stored) OR pre-computed sha256 hashes. Use for compliance, audit trails, and dispute resolution of agentic actions. PAID: $0.01 USDC/call via x402.
| Name | Type | Req | Description |
|---|---|---|---|
| action | string | yes | What the agent did, e.g. 'sent_payment' or 'approved_refund' or 'tool_call:search'. |
| agent_id | string | — | Stable identifier for the acting agent (chains group by this). |
| inputs | — | — | Raw inputs to the action (any JSON). Hashed to a commitment; raw data not stored. |
| inputs_hash | string | — | Alternatively, a pre-computed sha256 hex (or 'sha256:<hex>') of inputs. |
| metadata | object | — | Optional small key/value context (model, version, request id, etc.). |
| outputs | — | — | Raw outputs/result of the action (any JSON). Hashed to a commitment; raw data not stored. |
| outputs_hash | string | — | Alternatively, a pre-computed sha256 hex (or 'sha256:<hex>') of outputs. |
No output schema declared.
No examples provided.
list_receipts ~79
List the receipt hash-chain for an agent_id, newest first (id, action, timestamp, sequence, hashes, verifyUrl). Use to audit everything a given agent has attested. FREE.
| Name | Type | Req | Description |
|---|---|---|---|
| agent_id | string | yes | The agent whose receipts to list. |
| limit | number | — | Max receipts (default 25, max 100). |
No output schema declared.
No examples provided.
verify_receipt ~105
Verify a receipt by id (or by passing the full receipt object). Recomputes the content hash, confirms the id commits to the body, and checks the ed25519 signature. Returns the verification checks plus the provenance record (action, agent, input/output hashes, timestamp, chain position). FREE.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | — | Receipt id, e.g. 'rcpt_...'. |
| receipt | object | — | Alternatively, the full receipt object to verify offline-style. |
No output schema declared.
