get_install_configGenerate a ready-to-paste configuration snippet for connecting a discovered MCP server to Claude Desktop or Cursor.1 finding
Why it is in this group
- The name "get_install_config" says "get": a word for reading.
- The description's first verb is "generate": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

  The server marks "get_install_config" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

  What this check looks for
Description, as the server wrote it
Generate a ready-to-paste configuration snippet for connecting a discovered MCP server to Claude Desktop or Cursor. MCP servers cannot auto-install — users must manually add configuration. This tool reduces that friction.

- title: Get install config
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false

Why it is in this group
- The description's first verb is "fetch": a word for reading.
Description, as the server wrote it
Fetch the live .well-known/mcp discovery manifest from an indexed MCP server. Returns transport endpoints, capabilities, and auth requirements needed to connect. Only works for servers that support MCP discovery.
Annotations the server declares
- title: Fetch a server's discovery manifest
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: true
get_index_statsGet overall statistics about the MCP Rating index: total servers, top categories, and last crawl time.No findings
Why it is in this group

  Matched text
  description: "...it started when we ran it ourselves (no credentials, on a schedule), how it is maintained (..."
  What this check looks for
Description, as the server wrote it
Get what is known about one MCP server by slug: whether it started when we ran it ourselves (no credentials, on a schedule), how it is maintained (last release, last code push, open issues, archived or deprecated), how to run it (install command or hosted endpoint), the keys it declares, its tools with their parameters, and roughly how many tokens its tool definitions cost. Listings are informational — verify details before installing.
Annotations the server declares
- title: Get MCP server details
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
list_categoriesList all available MCP server categories with the count of servers in each.No findings
Why it is in this group
- The name "list_categories" says "list": a word for reading.

List all available MCP server categories with the count of servers in each.
Annotations the server declares

search_serversSearch the MCP Rating index of MCP servers.No findings
Why it is in this group
- The name "search_servers" says "search": a word for reading.
Description, as the server wrote it
Search the MCP Rating index of MCP servers. Returns matches for a query, optionally filtered by category and sorted by quality, stars, downloads, recency, or name, each marked with the outcome of our own start test when we have run one, and with its last release and last code push dates where we know them. Quality scores are algorithmic estimates.
Annotations the server declares
- title: Search MCP servers
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false

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.

Install

Pinned to version 0.2.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http search https://mcprating.io/mcp/

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change, 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. It assumes the server is installed as search. Review it before you use it.

Anlyon alternative

1 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.
