## 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 2026-11-04.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 6 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 84/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 704 tokens (~117/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% 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 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 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.

## Install

### How do I install the io.github.macek166/syntropy-mcp server?

io.github.macek166/syntropy-mcp is a hosted endpoint at https://api.synproof.ai/v1/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (6)

### `syntropy_verify` (~280 tokens)

Put a falsifiable claim (thesis), contract clause, scientific hypothesis, or AI output on formal adversarial trial against explicit ground-truth axioms and/or a Small World (@domain:tag) using Synproof's 5-sieve Syntropy dialectical engine. Returns a deterministic CONFIRMED or REFUTED verdict, winning thesis, refuting argument, and triggered axioms.

Input parameters:

- `enable_research` (boolean): Whether to enable external academic/statutory research tools during debate.
- `initial_axioms` (array): Optional list of explicit ground-truth axioms that strictly override model priors.
- `max_failures` (integer): Sceptical exhaustion limit (number of failed attack attempts required to confirm, 1-10).
- `model_name` (string): Underlying model ('gemini-2.5-flash', 'gemini-2.5-pro', 'anthropic/claude-3.5-sonnet', 'deepseek/deepseek-r1').
- `thesis` (string, required): The specific, declarative claim to put on trial.
- `world` (string): Optional Small World handle(s) such as '@pravo:obcansky-zakonik-cz', '@law:insolvency-code', '@law:contract-act', or '@law:brrd-isda'.

### `syntropy_list_worlds` (~73 tokens)

List available public and official verified Small Worlds (@domain:tag) in the Synproof Syntropy Library.

Input parameters:

- `domain` (string): Optional domain filter (e.g. 'pravo', 'law', 'medicine', 'physics', 'finance').
- `search` (string): Optional keyword search query.

### `syntropy_get_world_axioms` (~64 tokens)

Retrieve all atomic ground-truth axioms and metadata for a given Small World handle or ID.

Input parameters:

- `world_id_or_handle` (string, required): Small World handle (e.g. '@pravo:obcansky-zakonik-cz') or UUID.

### `syntropy_fork_world` (~65 tokens)

Create an isolated private fork of a public Small World so custom rules can be ingested without altering public axioms.

Input parameters:

- `title` (string): Title for the new private fork.
- `world_id_or_handle` (string, required): Source Small World handle or ID to fork.

### `syntropy_ingest_axioms` (~132 tokens)

Extract and synchronize atomic axioms from raw text or a JSON record into a Small World via Axiomat with deduplication and conflict resolution.

Input parameters:

- `on_conflict` (string): Conflict resolution policy when new axioms contradict existing ones.
- `payload` (object): Optional structured JSON/database record to compile into axioms.
- `source_reference` (string): Citation or source identifier for the ingested axioms.
- `text` (string): Raw regulatory, contractual, or policy text to compile into atomic axioms.
- `world_id_or_handle` (string, required): Target Small World handle or UUID.

### `syntropy_get_onboarding_guide` (~90 tokens)

Return the complete interactive Synproof Syntropy Customer Implementation & Onboarding Skill (SKILL.md). Call this tool whenever the user asks to integrate, set up, or connect Syntropy into their project so you know which questions to ask (ground-truth sources, max_failures iterations, on_refuted behavior, API keys) and which SDK/Proxy code templates to apply.
