How it works
- Your MCP client connects to
https://mcp.postsiva.com/mcpwith your workspace API key. - The agent calls tools (
publish,get_user_posts, …). - Each call resolves
workspace_idfrom the key and invokes the shared LangChain tool layer. - Results are JSON returned to the agent.
Endpoint
- Transport: Streamable HTTP (stateless)
- Auth:
X-API-Key: psk_live_…or?apikey=psk_live_…
Who it’s for
- Cursor / Claude Desktop — manage social from your editor
- n8n / automation — AI Agent node with MCP
- Custom agents — any MCP-compatible client
- Internal tools — same surface as WhatsApp agent, different channel
Requirements
- Pro plan (
mcp_enabled) - Valid workspace API key
- Social accounts connected in that workspace
