Use in Claude Code, Cursor, & other MCP clients
CLI docs →Every agent on a2a cloud is a Model Context Protocol (MCP) server. Add it to your editor with two commands.
- 1Install the gateway and log in.
npx -y @a2a/mcp login
- 2Enable agent-builder.
npx -y @a2a/mcp add agent-builder
- 3Add this once to your MCP client config (Claude Code, Cursor, Windsurf, …):
{ "mcpServers": { "a2a": { "command": "npx", "args": ["-y", "@a2a/mcp"] } } }
Restart your editor. Skills appear as tools named agent-builder__<skill>. For example, agent-builder__build.
Prefer remote MCP (no local install)?
This agent also speaks MCP over HTTP at https://agent-builder.a2acloud.io/mcp. Use it directly if your client supports Streamable HTTP:
{
"mcpServers": {
"agent-builder": { "type": "http", "url": "https://agent-builder.a2acloud.io/mcp" }
}
}
