Anlyon alternative

16 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.

Tools

Grouped by what each tool does, most consequential first. Open one for its reasons and full description; descriptions are the publisher's own words.

    Why it is in this group

    • The input addresses people (input.to): what it sends cannot be taken back.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

    What it can reach

    • outboundThe input takes a destination (input.to): what the tool writes goes there.

      What this check looks for
    • Warn

      The server marks "muhabbit_record_verify" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

      Matched text

      annotations: {"readOnlyHint":true,"openWorldHint":false}; The input addresses people (input.to): what it sends cannot be taken back.

      What this check looks for
    Description, as the server wrote it
    Recompute the public record's hash chain server-side over [from, to], at most 1000 entries (no bounds: the latest 1000). Returns ok, checked and head_hash, or the first broken id and the reason (prev_hash_mismatch, hash_mismatch, endpoint_missing). Limited to 5 calls a minute per client. (Free: no credentials needed.)

Changes things 15Claude Code: ask
  • muhabbit_alertOne exchange security alert with its evidence signals, sources and timeline.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.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    One exchange security alert with its evidence signals, sources and timeline. Takes the id from muhabbit_alerts, or the article_id of an alert headline seen in muhabbit_events. A confirmed alert is free; an unconfirmed (suspected) one answers 403 alert_unconfirmed unless include_unconfirmed is true, which reads the paid route. (Free when include_unconfirmed is false, the default, and the alert is confirmed. Otherwise paid: x402 payment, or an API key or wallet token on a paid plan.)

      What this check looks for
    Description, as the server wrote it
    Exchange hack and drain alerts from Muhabbit's incident engine (large outflows to unlabelled wallets, withdrawal halts, security-researcher posts, exchange statements). One item per incident: tier (suspected = unconfirmed, confirmed), exchange, headline, USD at risk, assets, evidence signals and sources, a timeline with named clocks, and links to its hash-chained public record entries. Newest update first. Use for 'is an exchange being hacked right now?' or 'any exchange incidents since T?'. Informational, not advice. (Free when tier is confirmed, the default; that feed needs no credentials and returns at most 20. Otherwise paid: x402 payment, or an API key or wallet token on a paid plan.)

      What this check looks for
    Description, as the server wrote it
    The public market-event feed: every headline Muhabbit's wire published, newest first. Each item is an entry of the hash-chained public record with three clocks in UTC ms (source_at = publisher, detected_at = our ingest, published_at = our publication), focus tags, a category and impact 0-100. Covers exchange listings, US CPI, jobs and Fed, crypto, macro and tech. Exchange security alert headlines appear here too (suspected ones start with 'Unconfirmed:'; their evidence is in muhabbit_alerts). Page with next_cursor. (Free: no credentials needed.)

    Description, as the server wrote it
    Raw public record entries in chain order from an id: each entry's frozen fields, prev_hash and hash, for offline verification. hash = sha256 over the canonical JSON bytes followed by prev_hash; the exact recipe is in /public/events/{id}/proof.

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.

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 out1
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.
