Nothing serious here today

Today is the operative word: we check ECCA every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 12

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

ecca
ecca_bts_divergence
Measures lexical and semantic divergence across candidate assertions to penalize sycophancy.
ecca_claim_protocol_validate
Check one ecca.claim-protocol 1.0 document for shape: versioned, engine slots only (no vendor names), split causes from the published taxonomy, question text only with consent, seal present. Returns ok with the error list; validates shape, never the record behind it.
ecca_decision_tournament
Evaluates multi-option decision matrix using minimax regret and Pareto ranking over candidate pathways.
ecca_learning
Learning and study skills: refine the question, fetch studies, and show named claims before the verdict. Applies evidence and claims checks; spends one solve.
ecca_money
Money and business: refine the question, fetch studies, and show named claims before the verdict. Applies evidence and claims checks; spends one solve.
ecca_nutrition
Nutrition and supplements: refine the question, fetch studies, and show named claims before the verdict. Applies evidence and claims checks; spends one solve.
ecca_pre_mortem
Executes an adversarial pre-mortem identifying failure modes and early warning indicators using empirical argument verification.
ecca_psychology
Psychology research: refine the question, fetch studies, and show named claims before the verdict. Applies evidence and claims checks; spends one solve.
ecca_refine
Use one keyed tier-quota slot to sharpen rough student questions without adding facts; return detected niches and refinement chips. A closed engine ceiling falls back locally.
ecca_research
Use one keyed tier-quota slot and dispatch-ceiling reservation to fetch and grade studies from scholarly indexes; return fetched evidence and explicit gaps.
ecca_synthesize
Compare answers from configured engines and inspect disagreement, with lexical similarity and final-answer agreement when measurable.
ecca_verify
Independently answer a question and compare the candidate against deterministic panel agreement. Show named dissent; spends one solve.

ECCA — questions

Answers built from our own checks of this server.

What can ECCA do?
It exposes 12 tools, read directly from the server on our last check. Among them: ecca_bts_divergence, ecca_claim_protocol_validate, ecca_decision_tournament, ecca_learning, ecca_money, ecca_nutrition and 6 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is ECCA working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 452 ms. The bar chart above shows every period we have measured.
How do I connect ECCA?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does ECCA need an API key?
No. ECCA completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 12 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is ECCA?
It answers our handshake in 452 ms on average, which is faster than 30% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
