MCP server registry for agents: 20 servers, scored
Every MCP server here is a product in the StackResolve registry that publishes an MCP server, ranked by its AgentReady score. The score is measured from public evidence on 41 signals, so an agent can pick the server most likely to work unattended. Reads are free over REST and MCP, no key.
Missing a server? Run an audit on its domain. If the audit finds a published MCP server, it appears here with its score.
Query this registry from your agent
StackResolve is itself a hosted MCP server. Connect it and your agent can search this registry, compare servers, read any profile, and resolve a task to the right tools. The handshake and registry reads need no key; audits and research are metered with a free tier.

Questions
What is an MCP server registry?
A registry lists MCP (Model Context Protocol) servers an agent can connect to, with enough detail to install one: the endpoint or package, the transport, and what tools it exposes. This registry adds an AgentReady score per server, measured from public evidence, so an agent can pick the server that is most likely to work unattended.
How is each MCP server scored?
Every product is audited on 41 signals across four pillars: DISCOVER (can an agent find it), UNDERSTAND (docs, OpenAPI, errors), ADOPT (self-serve signup, SDKs, MCP, CLI), and OPERATE (predictable output, rate limits, retries). The score is the weighted share of applicable signals that pass. StackResolve sells none of these tools, so the score is independent.
Can an agent query this registry directly?
Yes. Registry reads are free and need no key. REST: POST https://api.stackresolve.dev/v1/search with {"query": "...", "requirements": {"mcp": true}}. MCP: connect to https://mcp.stackresolve.dev/mcp and call search_tools, get_profile, or list_registry. The CLI is npm i -g stackresolve.
How do I add my MCP server to the registry?
Run an audit on your domain at stackresolve.dev/audit. If the audit finds a published MCP server, the product appears here with its score. Claim the profile to track the score, fix the issues that cost points, and embed the badge.
Which editors can install servers from here?
Claude Code (claude mcp add), Codex (config.toml or JSON), and Cursor (mcp.json) are covered on every profile. Any client that speaks streamable HTTP or stdio MCP works the same way.
