iCallAgent Public API (candidate MCP)
iCallAgent operates an MCP server, but it is NOT a public agent surface. It exists to serve the iCallAgent agent RUNTIME during live calls (knowledge-base search, CRM actions, integrations) over SSE at GET /api/mcp/sse and POST /api/mcp/messages/, and requires a widget_id plus a runtime-issued `token` secret to open a session (an anonymous tools/list returns HTTP 400 "session_id is required"). Its docs state plainly it is "not designed as a general-purpose endpoint for third-party MCP clients like Claude Desktop or Cursor", and the tool set is per-agent and dynamic. It is therefore not cataloged as a reachable remote MCP server. Below is a CANDIDATE tool list derived from the public REST operations, for reference only — no such server is published.
One-click install for Cursor, VS Code, Claude, and 20+ other MCP clients, powered by API Commons MCP Install — visit install.apicommons.org for more information.

About MCP
The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.

Work with this as data
Every MCP server here is available over the APIs.io API and to AI agents over MCP.
