Bilt MCP Server

Connect an MCP-compatible AI client to Bilt to create and manage mobile app projects.

Connection details

Setting	Value
URL	https://mcp.bilt.me/mcp
Transport	Streamable HTTP
Authentication	Authorization: Bearer <Bilt API token>

Create an API token at Bilt API keys. The legacy /mcp/sse endpoint is no longer available.

Client setup

Claude Desktop

Claude Desktop launches local MCP commands from claude_desktop_config.json. Use mcp-remote to bridge stdio to Bilt and attach the API-key header:

{
  "mcpServers": {
    "bilt": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.bilt.me/mcp",
        "--transport",
        "http-only",
        "--body-timeout",
        "0",
        "--header",
        "Authorization:${BILT_AUTH_HEADER}"
      ],
      "env": {
        "BILT_AUTH_HEADER": "Bearer bilt_live_YOUR_TOKEN_HERE"
      }
    }
  }
}

Keep Authorization:${BILT_AUTH_HEADER} as one argument, without a space after the colon. On Windows, if Claude resolves npx through a broken Program Files path, set command to the absolute npx.cmd path or its 8.3 short-path equivalent.

Do not add Bilt through Claude's custom connector UI unless it supports a static Authorization header. Without that header, it may attempt OAuth, which Bilt does not currently support.

Cursor

Add this to .cursor/mcp.json:

{
  "mcpServers": {
    "bilt": {
      "url": "https://mcp.bilt.me/mcp",
      "headers": {
        "Authorization": "Bearer bilt_live_YOUR_TOKEN_HERE"
      }
    }
  }
}

OpenClaw

Add this to ~/.openclaw/openclaw.json:

{
  "mcp": {
    "servers": {
      "bilt": {
        "url": "https://mcp.bilt.me/mcp",
        "transport": "streamable-http",
        "headers": {
          "Authorization": "Bearer bilt_live_YOUR_TOKEN_HERE"
        }
      }
    }
  }
}

Restart the OpenClaw gateway after changing the configuration.

For another client, use native Streamable HTTP only if the client supports custom Authorization headers. Otherwise, use the same mcp-remote stdio bridge shown for Claude Desktop. Client configuration field names are not universal.

Available tools

Bilt exposes seven tools:

Tool	Purpose
bilt_list_projects	List projects owned by the authenticated user
bilt_get_project	Get one project by projectId
bilt_create_project	Create a project from a name and optional description
bilt_get_session	Get session and workflow state for a projectId
bilt_send_message	Send build instructions or answer paused workflow questions
bilt_cancel_workflow	Cancel the active workflow for a projectId
bilt_get_messages	Get conversation history for a projectId

All public input fields use camelCase. bilt_send_message accepts a projectId and either a message or structured question answers. Question answers are passed as a JSON string and require the paused response's workflowId:

{
  "projectId": "project-id",
  "workflowId": "workflow-id",
  "answers": "[{\"questionIndex\":0,\"selectedOptions\":[\"Option A\"]}]"
}

There is no separate resume tool. If a workflow pauses for questions, answer them with bilt_send_message. If it pauses for secrets or a Supabase connection, open the returned projectUrl, complete the requested action there, and the workflow will resume automatically.

Queued workflows count as active. Before sending unrelated work, call bilt_get_session and wait until hasActiveWorkflows is false.

Raw HTTP

MCP clients must send Accept: application/json, text/event-stream:

curl -N https://mcp.bilt.me/mcp \
  -H 'Authorization: Bearer bilt_live_YOUR_TOKEN_HERE' \
  -H 'Accept: application/json, text/event-stream' \
  -H 'Content-Type: application/json' \
  -H 'Mcp-Protocol-Version: 2025-03-26' \
  --data '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-03-26","capabilities":{},"clientInfo":{"name":"curl","version":"1.0.0"}}}'

Use an MCP client for normal operation; the raw request is only a transport check.

Migration from legacy SSE

Existing configurations must:

1. Change https://mcp.bilt.me/mcp/sse to https://mcp.bilt.me/mcp.
2. Select Streamable HTTP and disable SSE fallback.
3. Keep the Bearer token in the Authorization header.
4. Update stale tool calls to the seven-tool camelCase contract above.
