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.

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

fetchRead one complete numbered part of a public MFM document/dataset.Reads private dataNo findings
Why it is in this group
- The name "fetch" says "fetch": a word for reading.
What it can reach
- private-dataThe description's first sentence says "read" and "document": it reads documents.
Description, as the server wrote it Read one complete numbered part of a public MFM document/dataset. Follow metadata.next_id until null for the entire source. Null/missing values are not zero. Data dates, units and source limitations must be respected.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
list_datasetsBrowse all public MFM catalog entries with explicit pagination.Reads text others writeNo findings
Why it is in this group
- The name "list_datasets" says "list": a word for reading.
What it can reach
- untrusted-inputThe description's first sentence says "browse": it reads web pages, which anyone can write.
Description, as the server wrote it Browse all public MFM catalog entries with explicit pagination. Narrow by kind: company, page or dataset. This lists availability, not a certification that every indicator is complete.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false

Why it is in this group
- The name "search" says "search": a word for reading.

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 outbound.
- Reads text others write1
- 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
Pinned to version 1.0.0. Values in angle brackets are yours to fill in.
claude mcp add --transport http mfm https://masteringfinancialmarkets.com/ai/mcpclaude mcp add --transport http mfm https://masteringfinancialmarkets.com/ai/mcpRun 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.
{
"permissions": {
"allow": [
"mcp__mfm__search",
"mcp__mfm__fetch",
"mcp__mfm__list_datasets"
],
"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 mfm. Review it before you use it.
Capability tags behind 2 rules
- mcp__mfm__fetch private-data
- mcp__mfm__list_datasets untrusted-input
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.
