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.

Why it is in this group
- The input addresses people (input.recipient): 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
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
- outboundThe input takes a destination (input.recipient): what the tool writes goes there.
Findings
- Warn
The server marks "federal_contract_awards" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

submit_requestSend a requirement to one of Plumbline's services.Can send data outNo findings
Why it is in this group
- The name "submit_request" says "submit": a word for a change.
- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
- The input carries an amount (input.budget.amount) and a currency, so it moves money.
- The input addresses people (input.geography.to): what it sends cannot be taken back.
What it can reach
- outboundThe input takes a destination (input.geography.to): what the tool writes goes there.
Description, as the server wrote it Send a requirement to one of Plumbline's services. It is kept with a reference number.

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.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write4
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out2
- 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.
The server marks "federal_contract_awards" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".
What this check looks forMatched text
annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The input addresses people (input.recipient): what it sends cannot be taken back.

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__plumbline__list_propositions",
"mcp__plumbline__describe_proposition",
"mcp__plumbline__entity_lookup"

"mcp__plumbline__screen_sanctions",
"mcp__plumbline__company_financial_facts",
"mcp__plumbline__federal_contract_awards"
],
"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 plumbline. Review it before you use it.
