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 Security74
- 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. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation. See how to fix → View diagnostics → Partial
- 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
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability63
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1668 tokens (~185/item across 9 items; 9 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 Management17
- Stability observed for 5 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 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 10 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

covenant_marketplace__quick_trade Prepare a service offer ~353
Prepare an unsigned service offer with a buyer, seller, price and optional deal structure. Create a general market, listing or reusable transaction archetype. quick_trade prepares the complete simple agreement in one call. Every record carries seven question dimensions. Credit/escrow/custom terms require adopted execution; no funds or inventory are inferred. Selected action: quick_trade.
| Name | Type | Req | Description |
|---|---|---|---|
| amount | integer | yes | Integer price in the payment asset's exact stated unit. For USD cents, 25 dollars is 2500 cents; never infer a currency conversion. |
| archetype | object | – | Optional exact reusable deal structure supplied by the caller; preparation does not execute it. |
| buyer | string | yes | The proposed buyer role and identifier; a role label does not prove authority. |
| compact | boolean | – | Return the supported compact view; retain the complete exact packet when approving. |
| context | string | yes | Caller-chosen exact context for this unsigned proposal. |
| description | string | yes | The work or resource being offered, including the intended deliverable. |
| payment_asset | object | yes | The exact namespace, identifier and unit of the proposed payment asset. Named resource; adapter and transfer_terms default to null and {}. Naming never proves title, custody or transfer. |
| seller | string | yes | The proposed seller role and identifier; a label does not verify the supplier. |
| settlement | object | – | Optional proposed settlement terms; no rail is connected or payment sent. Optional explicit settlement terms. A pinned archetype settlement may be repeated exactly, but cannot be silently replaced. |
| terms | object | – | Optional exact additional terms to preserve in this unsigned offer. Optional exact inspection, correction, return or other terms adopted in this first offer. |
No output schema declared.
No examples provided.
covenant_review__authority Check declared authority ~221
Inspect supplied role summaries and any supported owner-local authority evidence. Inspect caller-supplied role summaries and any supported local authority evidence. Each agreements row has exactly id, kind and parties (role to direct Ed25519 public key). Do not pass a contract-draft wrapper. Read https://jupie202020.pythonanywhere.com/review-reference.json for examples. A declared role is not verified permission; this does not authorize signing, payment or execution.
| Name | Type | Req | Description |
|---|---|---|---|
| agreements | array | yes | Caller-declared role summaries. Each row has exactly id, kind and parties; parties maps role names to supported public verification keys. These are not signed contract wrappers. |
| expected_heads | array | – | Optional retained sorted causal heads for the group review. |
| grants | array | – | Optional exact grant records for owner-local access review; do not provide private keys or credentials. |
| group | string | – | Optional exact group reference; it does not appoint a controller or grant authority. |
| policies | array | – | Optional exact policy records; declarations are separate from installed authority. |
No output schema declared.
No examples provided.
covenant_review__evidence Check supplied proofs ~129
Check supplied proof envelopes against the supported installed verifiers and exact expectations. Check supplied proof envelopes with the supported installed verifiers. Read https://jupie202020.pythonanywhere.com/review-reference.json for item fields. Empty input reports no proofs supplied. A verified proof covers its exact statement and assumptions, not outside truth or execution permission.
| Name | Type | Req | Description |
|---|---|---|---|
| agreement_ids | array | yes | Exact agreement identifiers already verified separately; a supplied identifier alone does not prove assent. |
| items | array | yes | Supplied proof envelopes and exact verifier/context/statement expectations. Empty input means no proofs were supplied. |
No output schema declared.
No examples provided.
covenant_review__review Review a work record ~261
Review a raw coordination case, its supplied agreements, approvals and remaining duties. Review an exact coordination case, its supplied approvals and remaining obligations. Read https://jupie202020.pythonanywhere.com/review-reference.json for the case format and a complete empty example. A contract draft is not a verified agreement. Case builders such as start/case/spec are installed SDK helpers, not tools on this public endpoint. No signing or execution.
| Name | Type | Req | Description |
|---|---|---|---|
| case | object | yes | A raw coordination case with version, title and agreements. A contract draft or prior review report is not a case. See the service review-reference.json. Exact coordination case. Use start or case to… |
| expected_id | string | – | Optional retained exact case SHA256 identifier. A mismatch refuses; never replace a trusted pin merely to pass. |
No output schema declared.
No examples provided.
