Anlyon alternative
8 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 8Claude Code: ask
arcane_bilateralObserved bilateral signal-intensity across seven tracked country pairs (volume and tone indices, plus an observed escalation stage).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 Observed bilateral signal-intensity across seven tracked country pairs (volume and tone indices, plus an observed escalation stage). An index of observed intensity between the pair, not a prediction of what happens next. Check as_of/stale.
arcane_capabilitiesWhat ARCANE's public World-Sense serves and what it explicitly does NOT serve, plus per-stream validation notes.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 What ARCANE's public World-Sense serves and what it explicitly does NOT serve, plus per-stream validation notes. ARCANE NOTICES present-state geopolitical risk from primary-source senses; it does not forecast, advise, or trade.
arcane_data_streamsLatest observations from ARCANE's primary-source physical senses (energy stocks, fires, sanctions, GPS interference, outages, and more) with provider, cadence, and attribution.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 Latest observations from ARCANE's primary-source physical senses (energy stocks, fires, sanctions, GPS interference, outages, and more) with provider, cadence, and attribution. Observed levels only; some senses go silent when their baseline saturates. Check as_of/stale.
arcane_deltasWhat changed since yesterday across ARCANE's domains and primary-source senses (observed diffs only).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 What changed since yesterday across ARCANE's domains and primary-source senses (observed diffs only). Grounding-sense items fire once at onset then go quiet, so absence of an item is not calm. Check as_of/stale.
arcane_domainDrill-down for one domain: observed risk/momentum series, current-state regime posterior, and news-coverage theme cards (coverage unusualness, not truth or importance).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 Drill-down for one domain: observed risk/momentum series, current-state regime posterior, and news-coverage theme cards (coverage unusualness, not truth or importance). ARCANE NOTICES the present; it does not predict. Check as_of/stale.
arcane_overviewCurrent ARCANE overview: Combined Threat Score, per-domain risk rows, cascade state, and cross-domain gauges as observed now.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 Current ARCANE overview: Combined Threat Score, per-domain risk rows, cascade state, and cross-domain gauges as observed now. ARCANE NOTICES the present; it does not predict or advise. Check as_of/stale before treating as current.

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 ARCANE's live scenario tracker: for each pre-registered scenario, where the world is on its branching map — checkpoint COMPLETION as N/M (confirming signals fired of total), a direction of resemblance, staleness, and which fork checkpoints have fired or are pending. A live STATE view, NOT a forecast: completion is not a probability and direction is resemblance, not odds. ARCANE never states a scenario's likelihood. Check as_of/stale.
arcane_trigger_chainsObserved multi-stage trigger-chain state for five domains (stage activation, z-scores, and chain health).No findings
Why it is in this group
- The name "arcane_trigger_chains" says "trigger": a word for a change.
Description, as the server wrote it Observed multi-stage trigger-chain state for five domains (stage activation, z-scores, and chain health). Descriptive state only, not a forecast; the chains were repaired 2026-07-02 and not yet exercised live. Check as_of/stale.
Only reads 2Show 2 read-only tools
arcane_score_treeHow the Combined Threat Score is composed: per-domain roll-ups, applied premiums, and the design weights behind them, each carrying a live/config provenance tag.No findings
Why it is in this group
- The name "arcane_score_tree" says "tree": a word for reading.
Description, as the server wrote it How the Combined Threat Score is composed: per-domain roll-ups, applied premiums, and the design weights behind them, each carrying a live/config provenance tag. Weights are design configuration, not fitted parameters. Check as_of/stale.
arcane_system_statusFreshness of every public ARCANE key: push time, source as_of, and stale flag.No findings
Why it is in this group
- The name "arcane_system_status" says "status": a word for reading.
Description, as the server wrote it Freshness of every public ARCANE key: push time, source as_of, and stale flag. Call this before treating any reading as current.
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.

The endpoint served tools/list without credentials, and the list has 8 tools that change things (8 write). Whether a call also works without credentials was not tested: tools are never called.
What this check looks forMatched text
https://mcp.arcaneforecasting.com/mcp: tools/list returned 10 tools to an anonymous client, including arcane_overview (write), arcane_deltas (write), arcane_domain (write), arcane_bilateral (write), arcane_data_streams (write) and 3 more
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.

}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 world-sense. 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.
