Clients and Compatibility
FlowMCP schemas work with any MCP-compatible client. This page covers the protocol they rely on, which clients support what, and what running them through the CLI gives you.
MCP — The Connecting Protocol
Section titled “MCP — The Connecting Protocol”The Model Context Protocol (MCP) is the standard through which AI clients access tools. It defines how tools are described, called, and how results are returned. Over 100 clients support MCP already — from Claude to ChatGPT to Cursor.
FlowMCP schemas are based on MCP and work with any compatible client. You are not locked into any specific provider.
Compatibility Table
Section titled “Compatibility Table”Not every client can do everything. Capabilities depend on which MCP features the client supports:
| Level | What is supported | Number of Clients | Examples |
|---|---|---|---|
| Level 1: Tools | Individual tool calls, Resources, Prompts | 46+ clients | Claude, ChatGPT, Cursor, VS Code Copilot, Cline, Continue |
| Level 2+3: Elicitation | Everything from Level 1 + Agent can ask follow-up questions | 16 clients | Claude Code, Claude Desktop, OpenClaw, Codex, Cursor, Postman |
| Custom CLI | Command-line interfaces for direct access | FlowMCP CLI, OpenClaw Plugin | For developers and automation |
What the levels mean: Primitives — Agents
As of: 2026-05-24. Current MCP client list: modelcontextprotocol.io/clients
Clients with Elicitation (Level 2+3)
Section titled “Clients with Elicitation (Level 2+3)”These 16 clients support Elicitation — the agent can ask follow-up questions for better answers: AIQL TUUI, Claude Code, Codex, Cursor, fast-agent, Glama, goose, Joey, mcp-agent, mcp-use, MCPJam, Memgraph Lab, Postman, Tambo, VS Code GitHub Copilot, and VT Code.
OpenClaw
Section titled “OpenClaw”OpenClaw is an open-source AI assistant gateway with a plugin system. The special feature: Cron Jobs — recurring queries that run automatically. For example, a daily mobility recommendation every morning at 7:30 AM.
