What the Belfort Data MCP server can do

The Belfort Data MCP server is published by belfortagent.xyz, a domain the MCP Registry verified. It has 14 tools. It can create or change data (2 tools: get_statements and get_ownership), but cannot delete data. 12 tools only read.

2 tools read private data (get_statements and get_macro).

The fixed checks matched 3 findings (tool-shadowing and annotation-conflict). Each one comes with the text it matched.

Its remote endpoint asks for sign-in.

Last scanned Nov 14, 2026, version 1.1.0.

    Why it is in this group

    • The name "get_ownership" says "get": a word for reading.
    • The description's first verb is "schedule": a word for a change.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

    Description, as the server wrote it
    Statements as filed, one document per filing and statement, newest filing first. Costs 3 credits. One page only: pass `limit` (1–20, default 4) and `cursor` from `meta.next_cursor`. Do not assume every page is fetched. A typical page of 4 documents is about 45 KB (median in the pilot sample); large pages stay under the API document budget (~4 MB).

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 untrusted-input or outbound.

Reads private data2
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 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

Belfort Data MCP server: questions and answers

Answered from the scan above, not from the publisher's description.

Is the Belfort Data MCP server safe?

No scan can promise that. What its definitions show: 14 tools, 2 of which can change, send or delete something, and 3 findings from fixed checks. Allow the reads, ask before each change, and deny the deletes; the permissions block on this page does that.

Can the Belfort Data MCP server delete data?

No tool is classed as destructive: going by their definitions, none of them deletes, cancels or revokes anything.

Can the Belfort Data MCP server do things that cannot be undone?

No tool is classed as irreversible: none of them sends, pays, publishes or merges, going by their definitions.

What tools does the Belfort Data MCP server have?

14 tools: 2 write, 12 read. get_statements, get_ownership, status, get_company, get_metrics, get_macro, get_insider_trades, get_form13f and 6 more.

Does the Belfort Data MCP server need sign-in or OAuth?

Yes. Its remote endpoint answered 401 without credentials, and no OAuth protected resource metadata was found.

Does the Belfort Data MCP server send data to outside services?

None of its tools sends, posts or publishes, or takes a recipient, channel or URL.

Has the Belfort Data MCP server changed its tools?

Not since anlyon.dev started tracking it. Last scanned Nov 14, 2026.
