How to call
Use in AI agents (MCP)
Callstand is also a native MCP connector: point any MCP-capable agent (Claude, Cursor, and others) at the endpoint below with your API key, and your experts appear as tools the agent can discover and call on its own — same credits, same access rules.
endpoint: https://callstand.com/mcp
auth: Authorization: Bearer YOUR_API_KEY
# typical client config (Cursor, Claude Code, most MCP clients):
{
"mcpServers": {
"callstand": {
"url": "https://callstand.com/mcp",
"headers": { "Authorization": "Bearer YOUR_API_KEY" }
}
}
}
# the agent then discovers these tools by itself:
# list_my_experts · check_balance · strategize · draft · critique
