## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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 2026-11-04.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs hatchling.build at install time, a recognised build step with no custom scripting around it.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 71/100
  - Repository check failed: the declared repository URL returned HTTP 404.
  - Cryptographically verified build provenance (signed, bound to CYAN-ECLIPSE-TECHNOLOGIES-LLC/eclipse-herald-mcp).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 7 days ago).
  - Security-disclosure policy not yet verified: we couldn't inspect the source repository.
- **Schema Quality & AI Usability**: 55/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 318 tokens (~63/item across 5 items; 5 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## MCP tools (5)

### `card_build` (~68 tokens)

Input parameters:

- `face` (string, required)
- `overrides` (object)

### `card_sign` (~66 tokens)

Input parameters:

- `face` (string, required)
- `overrides` (object)

### `card_verify` (~39 tokens)

Validate a card's schema and verify its JWS signature against the local JWKS. Tampered cards are rejected.

Input parameters:

- `card_path` (string, required)

### `gateway_delegate` (~110 tokens)

Delegate a task through the governed gateway to a LOCAL test agent (echo, research-stub, silent, injecting): verify card -> certify-check -> mandate (budget cap, expiry) -> dispatch -> quarantine ingest -> receipt-on-delivery. No artifact, no payment.

Input parameters:

- `agent_id` (string, required)
- `budget_cap_credits` (string, required)
- `card_path` (string, required)
- `prompt` (string)
- `skill_id` (string, required)

Input parameters:

- `limit` (integer)

### Is the Eclipse Herald MCP server safe to use?

That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Eclipse Herald MCP server expose?

### Is the Eclipse Herald MCP server still maintained?
