What the Storefinch MCP server can do

The Storefinch MCP server is published by storefinch.com, a domain the MCP Registry verified. It has 5 tools. It can create or change data (2 tools: export_leads and verify_websites), but cannot delete data. 3 tools only read.

1 tool reads private data (get_place); 1 tool brings in text other people can write (verify_websites).

None of the fixed checks matched anything in its tool definitions. That is not a safety guarantee.

Its remote endpoint asks for sign-in and publishes OAuth metadata.

Last scanned Nov 6, 2026, version 1.1.0.

Tools

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

Changes things 2Claude Code: ask
  • export_leadsBuild a lead list as a CSV download link (valid 24 h): name, category, address, phone, website, email, socials, coordinates, source and license per row.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.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Build a lead list as a CSV download link (valid 24 h): name, category, address, phone, website, email, socials, coordinates, source and license per row. Needs a category and a location. Rows count against the plan's monthly export quota; preview shows the first rows.

    • idempotentHint: true
    • openWorldHint: false

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • 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.
    Description, as the server wrote it
    Check whether each place's listed website is live right now (status per place: live, live_bot_protected, redirected_elsewhere, page_not_found, dead_domain, unreachable, ...). Use before outreach. Each place checked counts as one call.

  • find_categoriesFind category ids to use with search_places / export_leads.No findings

    Why it is in this group

    • The name "find_categories" says "find": a word for reading.
    Description, as the server wrote it
    Find category ids to use with search_places / export_leads. Returns matching ids, their place in the taxonomy, and how many US places each has. Broader ids include all their subcategories.

    Why it is in this group

    • The name "get_place" says "get": a word for reading.

    What it can reach

    Why it is in this group

    • The name "search_places" says "search": a word for reading.
    Description, as the server wrote it
    Search US businesses and places by category, name and location. Needs at least one location filter or a name. Returns up to 100 compact results per call plus the total match count; use export_leads instead when you need more than a few pages.

    Annotations the server declares

    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
    • readOnlyHint: true

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 private data1
Reads files, mail, messages, databases, secrets, calendars or repositories.
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.

Remote posture

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

Claude Code permissions

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

}

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 storefinch. Review it before you use it.

Storefinch MCP server: questions and answers

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

Is the Storefinch MCP server safe?

No scan can promise that. What its definitions show: 5 tools, 2 of which can change, send or delete something, and 0 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 Storefinch MCP server delete data?

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

Can the Storefinch 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 Storefinch MCP server have?

5 tools: 2 write, 3 read. export_leads, verify_websites, find_categories, search_places and get_place.

Does the Storefinch MCP server need sign-in or OAuth?

Yes. Its remote endpoint answered 401 without credentials, and it publishes OAuth protected resource metadata (RFC 9728); its authorization server supports dynamic client registration.

Does the Storefinch MCP server send data to outside services?

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

Has the Storefinch MCP server changed its tools?

Not since anlyon.dev started tracking it. Last scanned Nov 6, 2026.
