Anlyon alternative
3 of these tools change something. Run those as governed actions.
Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.
Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

Changes things 3Claude Code: ask
syntropy_fork_worldCreate an isolated private fork of a public Small World so custom rules can be ingested without altering public axioms.No findings
Why it is in this group
- The name "syntropy_fork_world" says "fork": a word for a change.
Description, as the server wrote it Create an isolated private fork of a public Small World so custom rules can be ingested without altering public axioms.
syntropy_ingest_axiomsExtract and synchronize atomic axioms from raw text or a JSON record into a Small World via Axiomat with deduplication and conflict resolution.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it Extract and synchronize atomic axioms from raw text or a JSON record into a Small World via Axiomat with deduplication and conflict resolution.
syntropy_verifyPut 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 (@domai…No findings
Why it is in this group
- The description's first verb is "put": a word for a change.
Description, as the server wrote it 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.
Only reads 3Show 3 read-only tools
syntropy_get_onboarding_guideReturn the complete interactive Synproof Syntropy Customer Implementation & Onboarding Skill (SKILL.md).No findings
Why it is in this group
- The name "syntropy_get_onboarding_guide" says "get": a word for reading.
Description, as the server wrote it 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.
syntropy_get_world_axiomsRetrieve all atomic ground-truth axioms and metadata for a given Small World handle or ID.No findings
Why it is in this group
- The name "syntropy_get_world_axioms" says "get": a word for reading.
Description, as the server wrote it Retrieve all atomic ground-truth axioms and metadata for a given Small World handle or ID.
syntropy_list_worldsList available public and official verified Small Worlds (@domain:tag) in the Synproof Syntropy Library.No findings
Why it is in this group
- The name "syntropy_list_worlds" says "list": a word for reading.
Description, as the server wrote it List available public and official verified Small Worlds (@domain:tag) in the Synproof Syntropy Library.
This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
Exfil surface
Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.
No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write0
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out0
- Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.
Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.
Findings
Matches of fixed checks, with the text they matched.
No check matched anything in these tool definitions. That is not a safety guarantee.
History
Changes to its tool definitions and to its remote endpoint, newest first.
No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Claude Code permissions
Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.
{
"permissions": {
"allow": [
"mcp__syntropy__syntropy_list_worlds",
"mcp__syntropy__syntropy_get_world_axioms",

"mcp__syntropy__syntropy_ingest_axioms"
],
"deny": []
}
}Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as syntropy. Review it before you use it.
Pin
Keep the decision: fail CI when the tools change, follow every change, or show a badge.
Pin in CI
Fail a build when the tools you reviewed are not the tools the server serves today.
