A fresh install of MCPFlo is seeded with @mcpflo/server-everything — MCPFlo’s own deterministic test-fixture server, which exercises every capability the app supports (tools, resources, prompts, elicitation, sampling, notifications). It’s a good place to start exploring before you connect a real server.

Adding your own server

1. Click + Add Server in the sidebar.
2. Enter a name and choose a transport:
   • stdio — provide the command and args (e.g. npx with args -y @modelcontextprotocol/server-memory), plus any environment variables.
   • Streamable HTTP — provide the URL, plus any request headers (e.g. Authorization: Bearer …).
   • Environment variables and headers use a key/value row editor and live in collapsible sections, so the form stays short until you need them.
   • An Advanced section exposes an optional connection timeout and MCP protocol version override.
   • Prefer pasting a config? Switch to JSON import and paste an mcpServers block (single or multiple entries) instead of filling out the form by hand.
3. Click Add Server.
4. Expand the server row — MCPFlo connects and discovers all tools, resources, and prompts automatically. If the server requires OAuth, your browser opens for sign-in and MCPFlo reconnects on its own.

Example: JSON import

{
  "mcpServers": {
    "memory": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-memory"]
    }
  }
}

Where config lives

Server configs are persisted with electron-store to config.json under the app’s user-data directory (secrets are encrypted via the OS keychain):

• macOS: ~/Library/Application Support/MCPFlo/config.json
• Windows: %APPDATA%/MCPFlo/config.json
• Linux: ~/.config/MCPFlo/config.json

Discovered capabilities are cached to disk per server under <user-data>/servers/<server-id>/capabilities.json, so they’re available immediately on the next launch before a fresh discovery runs.

Next steps

Once a server is expanded, head to Browsing Capabilities to explore its tools, resources, and prompts, or jump straight to Invoking Tools & Prompts to make your first call.
