## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-06.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 40/100
  - Verified sse transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 87/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 586 tokens (~73/item across 8 items; 6 tools + 2 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Install

### How do I install the MCP Rating server?

MCP Rating is a hosted endpoint at https://mcprating.io/mcp/sse, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (6)

### `search_servers` (~136 tokens)

Search MCP servers

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.

Input parameters:

- `category` (string): Category slug to filter by (e.g. 'developer-tools')
- `limit` (number): Max results (default 20)
- `query` (string): Search query to match against server names
- `sortBy` (string): Sort order

### `get_server` (~108 tokens)

Get MCP server details

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.

Input parameters:

- `slug` (string, required): The server's unique slug identifier

### `list_categories` (~22 tokens)

List server categories

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

### `get_index_stats` (~29 tokens)

Get index statistics

Get overall statistics about the MCP Rating index: total servers, top categories, and last crawl time.

### `get_install_config` (~101 tokens)

Get install config

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.

Input parameters:

- `client` (string): Target client (default: claude_desktop). 'generic' returns a transport-neutral {command,args,env} object; 'surge' returns the Surge install shape.
- `slug` (string, required): The server's unique slug identifier

### `discover_server` (~59 tokens)

Fetch a server's discovery manifest

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.

Input parameters:

- `slug` (string, required): The server's unique slug identifier

## Common questions

### What is the MCP Rating server?

MCP Rating is listed in the public MCP registry as io.mcprating/search. Search MCP servers, with our own start-test results, required keys, tools and token cost. This page covers its hosted endpoint (https://mcprating.io/mcp/sse).

### Is the MCP Rating server safe to use?

MCP Rating scores 84 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the MCP Rating server expose?

MCP Rating exposes 6 tools: search_servers, get_server, list_categories, get_index_stats, get_install_config, discover_server. Their descriptions and schemas cost roughly 455 tokens of context every time the server is loaded.

### Does the MCP Rating server require authentication?

No. We connected to MCP Rating without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the MCP Rating server still maintained?

MCP Rating is still listed as active in the MCP registry. We last reached this channel on 6 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the MCP Rating server?

VerifyMCP ran 13 checks on MCP Rating, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
