Anlyon alternative
Run the operations that matter 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.

get_eventsRecent classified market events for a symbol.Reads text others writeNo findings
Why it is in this group
- The name "get_events" says "get": a word for reading.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it Recent classified market events for a symbol. Kill-switch trio: hack_exploit, regulation, delisting — the reference integrations stand aside for 24h after one. Report the event headline and source link, not just a risk flag.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: true
get_sentimentLatest news-sentiment signal per symbol (batch up to 50 in one call — one signal per asset per hour, so never poll faster than hourly).Reads text others writeNo findings
Why it is in this group
- The name "get_sentiment" says "get": a word for reading.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it Latest news-sentiment signal per symbol (batch up to 50 in one call — one signal per asset per hour, so never poll faster than hourly). On the free plan, symbols outside BTC-USD/ETH-USD/SOL-USD are 24h delayed: check `timestamp` and disclose staleness.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: true
get_sentiment_historyPoint-in-time sentiment series for backtesting: `bucket` is the as-of time, no lookahead.Reads text others writeNo findings
Why it is in this group
- The name "get_sentiment_history" says "get": a word for reading.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it Point-in-time sentiment series for backtesting: `bucket` is the as-of time, no lookahead. `from`/`to` are clamped to your plan's history window and to its per-request span, then echoed back — check them rather than assuming. `reconstructed: true` buckets were rebuilt from archival news, not live-collected; disclose the mix in any backtest.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: true
get_symbolsThe supported symbol universe with each symbol's free-plan freshness.No findings
Why it is in this group
- The name "get_symbols" says "get": a word for reading.
Description, as the server wrote it The supported symbol universe with each symbol's free-plan freshness. Static — costs no quota and needs no API key.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
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 outbound.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write3
- 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.
Install

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__sentiment__get_sentiment",
"mcp__sentiment__get_sentiment_history",
"mcp__sentiment__get_events",
"mcp__sentiment__get_symbols"
],
"ask": [],
"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 sentiment. Review it before you use it.

Pin
Keep the decision: fail CI when the tools change, follow every change, or show a badge.
