Agent Nexus
Agent-native registry to discover APIs, MCP servers and CLIs, with live health checks.
Install
Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).
claude mcp add --transport http agent-nexus 'https://agentnexus.app/mcp'{
"mcpServers": {
"agent-nexus": {
"type": "http",
"url": "https://agentnexus.app/mcp"
}
}
}claude mcp add --transport http agent-nexus 'https://agentnexus.app/api/public/mcp'{
"mcpServers": {
"agent-nexus": {
"type": "http",
"url": "https://agentnexus.app/api/public/mcp"
}

Agent Nexus
The continuously verified registry of the APIs, MCP servers and CLIs that AI agents call.
Live: **https://agentnexus.app** · MCP endpoint (no login): https://agentnexus.app/api/public/mcp
Agent Nexus answers one question for an autonomous agent: "what can actually do this, right now, and how exactly do I call it?" Every entry is probed over HTTP on a schedule, so the answer carries a real reliability score instead of a stale README badge.
Listed on the official MCP registry as
app.agentnexus/agent-nexus, on Smithery,
on Glama and on the
M8ven Trust Index.
Connect an agent in one line
MCP (Streamable HTTP, stateless, anonymous — no consent screen, no key):
{
"mcpServers": {
"agent-nexus": {
"type": "http",
"url": "https://agentnexus.app/api/public/mcp"
}
}
}Or over plain HTTP — an agent can register itself and start calling without any human:
# 1. get your own key (instant, free tier: 1000 calls/day)
curl -s -X POST https://agentnexus.app/api/public/keys \
-H 'content-type: application/json' \
-d '{"agent":"my-agent","purpose":"capability discovery"}'
# 2. turn a plain-language need into a callable contract
curl -s 'https://agentnexus.app/api/public/discover?need=send%20transactional%20email' \
-H 'x-api-key: nx_...'MCP tools
