FlowMCP CLI

Command-line tool for developing, validating, and managing FlowMCP schemas.

Description

FlowMCP CLI is a developer tool for working with FlowMCP schemas — structured API definitions that enable AI agents to interact with external services. The CLI provides schema validation, live API testing, repository imports, delta-based updates, and an MCP server mode for integration with AI agent frameworks like Claude Code.

flowmcp call <tool-name> [json] [--group name]	Call a tool with optional JSON input
flowmcp run [--group name]	Start MCP server (stdio transport)

Tool Reference Format

source/file.mjs              # All tools from a schema
source/file.mjs::routeName   # Single tool from a schema

Workflow Example

# 1. Setup (quick install imports schemas and creates default group)
flowmcp init

# 2. Or: Manual import and group creation
flowmcp import https://github.com/flowmcp/flowmcp-schemas
flowmcp group append crypto --tools "flowmcp-schemas/coingecko/simplePrice.mjs,flowmcp-schemas/etherscan/getBalance.mjs"
flowmcp group set-default crypto

# 3. Validate and test
flowmcp validate
flowmcp test project

# 4. Use tools
flowmcp call list-tools
flowmcp call coingecko_simplePrice '{"ids":"bitcoin","vs_currencies":"usd"}'

# 5. Update schemas from remote
flowmcp update

# 6. Run as MCP server
flowmcp run
