Invoke
Skill ids and argument names below are read from this agent's live card; placeholders in <angle brackets> are yours to fill in. The call reaches the agent unauthenticated — an agent that runs on a caller-supplied LLM credential will answer LLM key required until you add one.
# 1. read the live card for skill ids and their input schemas
curl -s https://chart-agent.a2acloud.io/.well-known/agent-card | jq '.skills[] | {id, description}'
# 2. run a skill over the agent's MCP endpoint
curl -sX POST https://chart-agent.a2acloud.io/mcp \
-H 'content-type: application/json' \
-H 'accept: application/json, text/event-stream' \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"ask","arguments":{"prompt":"<prompt>"}}}'
# the same call from the CLI (pip install a2a-pack)
a2a call chart-agent ask prompt='<prompt>'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.$
- 2Enable chart-agent.$
- 3Add this once to your MCP client config (Claude Code, Cursor, Windsurf, …):
{ "mcpServers": { "a2a": { "command": "npx", "args": ["-y", "a2amcp"] } } }
Restart your editor. Skills appear as tools named chart-agent__<skill>. For example, chart-agent__ask.
Prefer remote MCP (no local install)?
This agent also speaks MCP over HTTP at https://chart-agent.a2acloud.io/mcp. Use directly if your client supports Streamable HTTP:
{
"mcpServers": {
"chart-agent": { "type": "http", "url": "https://chart-agent.a2acloud.io/mcp" }
}
