The agent-friendliness score for 416 APIs
An independent scorecard your coding agent can query at runtime. Works with Claude Code, Codex, Cursor, Copilot, Cline, Windsurf - any MCP-compatible agent. Picks the right API using a transparent 8-signal rubric. Free, open, no auth.
Add to ~/.cursor/mcp.json (or via Settings → MCP):
{
"mcpServers": {
"clirank": {
"command": "npx",
"args": ["-y", "clirank-mcp-server@latest"]
}
}
}Works with any MCP-compatible agent. Pick your client, copy the config, then ask your agent to use CLIRank before choosing an API. See full docs →
Quick activation for your agent
Give your coding agent access to CLIRank for runtime API decisions.
# MCP server — works with any compatible agentnpx clirank-mcp-server@latest# Or hit the API directlycurl "https://clirank.dev/api/discover?q=send+transactional+emails&limit=3"Streamable HTTP endpoint for agents that support it.
Agent query patterns
Agents search by task, not by vendor category
CLIRank turns real agent-style jobs into API guides, decision checks, and runtime endpoints your coding agent can use before it writes integration code.
For AI Agents
Query the directory programmatically. No scraping, no auth required.
