Anlyon alternative
4 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 4Claude Code: ask
dispute_findingDispute a finding in one of Blackhull's x402 service reports.Can send data outNo findings
Why it is in this group
- The input takes a statement or command to run (input.code), which can change anything it can reach.
What it can reach
- outboundThe input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
Description, as the server wrote it Dispute a finding in one of Blackhull's x402 service reports. Free. It is rechecked from fresh data on the next daily run and upheld or withdrawn; every outcome is public at /disputes.
economy_moversThis week's fastest-moving agent repositories on GitHub (star deltas) and newly seen MCP servers.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.

request_capabilityCould not find a tool or data source you need?No findings
Why it is in this group
- The name "request_capability" says "request": a word for a change.
Description, as the server wrote it Could not find a tool or data source you need? Say what it is and the most you would pay per call (USDC). Free. Stored only as a short label — do not include personal data. Returns the closest paid services Blackhull sees, if any.

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.
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__listening-post__search_mcp_servers"
],
"ask": [
"mcp__listening-post__economy_movers",
"mcp__listening-post__what_agents_want",
"mcp__listening-post__dispute_finding",
"mcp__listening-post__request_capability"
],
"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 listening-post. 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.
