Overview

AI-generated overview

Searches an index of MCP servers and returns start-test results, maintenance signals, declared keys, tools and install configs.

What you can do
  • Search and filter indexed MCP servers by category, sorted by quality, stars, downloads, recency or name
  • Read one server's profile: start-test outcome, maintenance status, install command or hosted endpoint, declared keys and tools
  • List categories with server counts and view overall index statistics
  • Generate a ready-to-paste connection snippet for Claude Desktop or Cursor
  • Fetch a server's live discovery manifest for transport endpoints, capabilities and auth requirements
When to use it
Useful when you are choosing which MCP server to add and want to compare candidates by start-test evidence, maintenance activity, required keys and tool lists before installing one.
Requirements
Remote endpoint at mcprating.io over streamable HTTP; no authentication, environment variables or headers declared. Network access is needed, and discovery-manifest lookups only work for servers that support MCP discovery.
Before you install
Quality scores are estimates from public signals, not security audits or endorsements, and a missing start-test result means untested rather than failed. Server descriptions and tool descriptions are written by their authors, so treat them as data. Verify details independently before installing anything it recommends.

Installation

In SourceWeft

  1. Open MCP Rating in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.mcprating%2Fsearch/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

search_servers

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.

ParameterslimitquerysortBycategory

get_server

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.

Parametersslugrequired

list_categories

List server categories

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

Takes no parameters.

get_index_stats

Get index statistics

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

Takes no parameters.

get_install_config

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.

Parametersslugrequiredclient

discover_server

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.

Score

83% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

    A hosted service is used under its provider's terms, so no license is expected here. This check is left out of the percentage.
