## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 89/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 61/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 737 tokens (~61/item across 12 items; 12 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 87/100
  - Stability observed for 26 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 84/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 53% of tool parameters carry a description.
- **Tool Safety**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "ecca_pre_mortem" implies "execute" and declares readOnlyHint instead, contradicting what its own name says it does.
  - An AI judge read all 12 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (12)

### `ecca_synthesize` (~147 tokens)

Compare answers from configured engines and inspect disagreement, with lexical similarity and final-answer agreement when measurable.

Input parameters:

- `antagonist` (boolean): When true, forces one engine to act as adversarial red-team antagonist.
- `depth` (string): intuitive and fast route to one engine; executive, pioneer and deep route a multi-engine dispatch (free callers: two engines first, expanding on measured divergence, one deep solve per day). Any othe…
- `model` (string): Label echoed in the result. Every value dispatches through the same registered engines; depth decides fast or multi-engine.
- `query` (string, required): The core inquiry, hypothesis, or decision challenge to synthesize.

### `ecca_pre_mortem` (~68 tokens)

Run a Pre-Mortem

Executes an adversarial pre-mortem identifying failure modes and early warning indicators using empirical argument verification.

Input parameters:

- `horizonMonths` (integer): Time horizon in months to simulate forward failure modes.
- `premise` (string, required): The strategic plan, architecture, or business premise to stress-test.

### `ecca_decision_tournament` (~58 tokens)

Compare Decision Options

## Common questions

### What is the ECCA MCP server?

ECCA is an MCP server listed in the public MCP registry as com.eccaai/ecca. Compare engine claims, inspect dissent and check study evidence for student questions. This page covers its hosted endpoint (https://eccaai.com/api/mcp).

### Is the ECCA MCP server safe to use?

ECCA scores 82 out of 100 on VerifyMCP. 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 ECCA MCP server expose?

ECCA exposes 12 tools: ecca_synthesize, ecca_pre_mortem, ecca_decision_tournament, ecca_bts_divergence, ecca_refine, and 7 more. Their descriptions and schemas cost roughly 737 tokens of context every time the server is loaded.

### Does the ECCA MCP server require authentication?

Yes. ECCA asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

### Is the ECCA MCP server still maintained?

ECCA is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
