Flex on the Job MCP MCP server

An official MCP server provided by Flex on the Job that allows AI agents to interact with the Flex platform. It exposes 139 typed tools for managing inventory, jobs, customers, invoices, purchasing, and sales orders. The server uses streamable HTTP transport, is stateless, and enforces the same permissions and rate limits as the REST API.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http flex-on-the-job-mcp https://app.flexonthejob.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add flex-on-the-job-mcp --url https://app.flexonthejob.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable flex-on-the-job-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "flex-on-the-job-mcp": {
      "url": "https://app.flexonthejob.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration

{
  "mcpServers": {
    "flex-on-the-job-mcp": {
      "type": "streamableHttp",
      "url": "https://app.flexonthejob.com/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start flex-on-the-job-mcp and inspect its tools.

VS Code configuration

  "servers": {
    "flex-on-the-job-mcp": {
      "type": "http",
      "url": "https://app.flexonthejob.com/mcp"

    "flex-on-the-job-mcp": {
      "url": "https://app.flexonthejob.com/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
