+# @a2a/mcp
+
+MCP gateway for a2acloud agents. It runs locally as a stdio MCP server and
+exposes deployed A2A agents as tools to Claude Code, Cursor, and other MCP
+clients.
+
+## Quickstart
+
+```bash
+npx -y @a2a/mcp login
+npx -y @a2a/mcp add <agent-name>
+npx -y @a2a/mcp doctor
+```
+
+Add it to your MCP client config:
+
+```json
+{
+  "mcpServers": {
+    "a2a": {
+      "command": "npx",
+      "args": ["-y", "@a2a/mcp"]
+    }
+  }
+}
+```
+
+Restart the client after adding or removing agents.
+
+## Commands
+
+```bash
+a2a-mcp login              # save control-plane credentials
+a2a-mcp whoami             # show current account
+a2a-mcp agents             # list agents visible to your account
+a2a-mcp add <name>         # expose one agent through this gateway
+a2a-mcp list               # list locally enabled agents
+a2a-mcp remove <name>      # stop exposing an agent
+a2a-mcp doctor             # probe enabled agents and count tools
+a2a-mcp logout             # clear local credentials
+```
+
+Running `a2a-mcp` with no command starts the MCP gateway over stdio.
