## Install

### How to install Flowsimp in Claude Code

1. Add the server

```bash
claude mcp add --transport http flowsimp https://flowsimp.com/mcp
```

2. Verify it's connected

```bash
claude mcp list
```

3. Sharing it with your team?

   Add `--scope project` to write it to .mcp.json in the repository root, which you can commit (with the secrets left as environment variables).

4. Use it in a session

   Ask Claude to use the tools this server exposes (e.g. create_flowchart, list_templates). It discovers them automatically.

### How to install Flowsimp in Claude Desktop

1. Open your MCP config

   macOS: ~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

2. Add this server

```json
{
  "mcpServers": {
    "flowsimp": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://flowsimp.com/mcp"
      ]
    }
  }
}
```

3. Why the wrapper?

   This is a remote (HTTP) server and Claude Desktop only launches local processes, so mcp-remote proxies the connection. It will open a browser window if the server needs OAuth.

4. Restart Claude Desktop

   The tools appear under the 🔌 menu once the app reloads.

### How to install Flowsimp in Cursor

1. Create / edit .cursor/mcp.json in your project

```json
{
  "mcpServers": {
    "flowsimp": {
      "url": "https://flowsimp.com/mcp"
    }
  }
}
```

2. Enable it

   Cursor Settings → MCP → toggle the server on. Tools become available to the Composer/Agent.

### How to install Flowsimp in Codex CLI

1. Add to ~/.codex/config.toml

```toml
[mcp_servers.flowsimp]
command = "npx"
args = ["-y", "mcp-remote", "https://flowsimp.com/mcp"]
```

2. Why the wrapper?

   Codex runs MCP servers as local processes, so mcp-remote bridges this HTTP endpoint to stdio.

3. Run Codex

   Codex loads MCP servers from config.toml on startup and exposes their tools to the agent.

### How to install Flowsimp in Windsurf

1. Edit ~/.codeium/windsurf/mcp_config.json

    }
  }
}

      "type": "http",
      "url": "https://flowsimp.com/mcp"
    }
  }
}
```

2. Start it

## Tools

- `create_flowchart` — Turn Mermaid flowchart or graph syntax, or an indented outline, into FlowSimp links. Use it when the steps already exist as text and someone needs a diagram they can view or edit. Returns JSON with shareUrl (a read-only /view# link), editUrl (opens the editor at /?board=), nodeCount, and connectionCount. An optional title is echoed in that JSON; it is not drawn on a shape. The diagram is compresse
- `list_templates` — List every built-in FlowSimp template. Use it when a starter diagram is a better fit than generating one from text. Takes no arguments. Returns JSON with a templates array of id, label, and editUrl. The ids are swimlane, decision-tree, user-flow, org-chart, flowchart, process, network, mind-map, data-flow, algorithm, bpmn, onboarding, and approval. Each editUrl opens that template in the editor.
