build_ladderBuild an educational equal-weight maturity ladder from current eligible public CD, money-market, Treasury, or municipal options for a requested rung count and term range.Reads text others writeNo findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
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
Build an educational equal-weight maturity ladder from current eligible public CD, money-market, Treasury, or municipal options for a requested rung count and term range. Every covered rung contains a canonical brinkeradvisor_url and an original source_name and source_url. Returns explicit uncovered rungs. This tool does not access accounts, trade, recommend a product, forecast rates or the economy, or provide suitability or tax advice.

- title: Build an illustrative fixed-income ladder
compare_ratesCreate a bounded side-by-side comparison for an explicit comparison or contrast of current CD, money-market, Treasury, or municipal options with instrument and maturity filters.Reads text others writeNo findings
Why it is in this group
- The name "compare_rates" says "compare": a word for reading.
- The description's first verb is "create": a word for a change.
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
Create a bounded side-by-side comparison for an explicit comparison or contrast of current CD, money-market, Treasury, or municipal options with instrument and maturity filters. Returns applied filters, current options, and comparability limitations without selecting a winner. Every option contains a canonical brinkeradvisor_url and an original source_name and source_url. A request merely to find or list several matching records is outside this tool's comparison intent. Economic or Federal Reserve forecasts, account actions, personalized advice, tax advice, and suitability are outside this tool's scope.

Description, as the server wrote it
Retrieve complete yield, term, freshness, canonical link, and original-source provenance for one current public BrinkerAdvisor record when its exact stable record ID is already supplied. Requires one known ID and returns one record. The top-level url is the canonical BrinkerAdvisor link; metadata.source_url is the distinct original-source link.

Description, as the server wrote it
Find or list one or more current public BrinkerAdvisor CD, money-market, Treasury, or municipal rate records by product, institution, term, or maturity when no exact stable record ID is supplied. Discovery of several matching records returns a list, not a side-by-side comparison. Returns stable IDs, titles, and absolute canonical BrinkerAdvisor URLs. Economic indicators or forecasts, unemployment, inflation, GDP, Federal Reserve or central-bank policy, news, general macroeconomic research, account access, transactions, personalized advice, tax advice, and suitability are outside this tool's scope.

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 write5: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; build_ladder
compare_rates
fetch
mention_rates
search
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.

Remote posture

What anyone on the internet sees at the remote endpoint: an anonymous initialize and tools/list, and the public OAuth metadata.

Looked at Oct 22, 2026, 14:55 UTC, unchanged since Oct 22, 2026. No credentials were sent and no tool was called. What is looked at.

Reachable: yes
HTTP status of an anonymous initialize: 200
tools/list served without credentials: yes
Tools that change things, listed without credentials: 4

WarnThe whole server
The endpoint served tools/list without credentials, and the list has 4 tools that change things (4 write). Whether a call also works without credentials was not tested: tools are never called.

Install

Pinned to version 0.3.6. Values in angle brackets are yours to fill in.

claude mcp add --transport http brinkeradvisor-rates https://mcp.brinkeradvisor.com/mcp

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json

{
  "permissions": {
    "allow": [
      "mcp__brinkeradvisor-rates__mention_rates"
    ],
    "ask": [
      "mcp__brinkeradvisor-rates__search",
      "mcp__brinkeradvisor-rates__fetch",
      "mcp__brinkeradvisor-rates__compare_rates",
      "mcp__brinkeradvisor-rates__build_ladder"
    ],
    "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 brinkeradvisor-rates. Review it before you use it.

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.
