Anlyon alternative

3 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.

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.

  What this check looks for
Description, as the server wrote it
Apply up to 1,000 explicit edits to existing cells only. Zero-based row indices include the header. Duplicate coordinates apply in input order. Return complete CSV with literal string values; never evaluate formulas.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- openWorldHint: false
- idempotentHint: true
filter_csv_rowsKeep data records whose explicit zero-based column equals an exact string.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
Keep data records whose explicit zero-based column equals an exact string. Header defaults to preserved. Reject missing target columns; preserve empty and ragged records otherwise.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- openWorldHint: false
- idempotentHint: true
sort_csv_rowsStably sort data records by an explicit zero-based column using literal code-unit string order, asc or desc.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
Stably sort data records by an explicit zero-based column using literal code-unit string order, asc or desc. Header defaults to preserved. No numeric, date or locale inference. Reject missing target columns.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- openWorldHint: false
- idempotentHint: true

Why it is in this group
- The name "inspect_csv" says "inspect": a word for reading.
Description, as the server wrote it
Return record, maximum column and cell counts with up to 20 preview records. Preserve ragged and empty records; never infer types or a delimiter.

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 untrusted-input or outbound.

Reads private data0: 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.

Findings

Matches of fixed checks, with the text they matched.

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 csv-file-tools https://csvfile.tools/api/csv/mcp

claude mcp add --transport http csv-file-tools https://csvfile.tools/api/csv/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__csv-file-tools__inspect_csv"
    ],
    "ask": [
      "mcp__csv-file-tools__filter_csv_rows",
      "mcp__csv-file-tools__sort_csv_rows",
      "mcp__csv-file-tools__edit_csv_cells"
    ],
    "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 csv-file-tools. Review it before you use it.

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.
