Use a Deployed Server

https://<app_id>.deployments.mcp-agent.com

Replace `<app_id>` with the hostname shown by `mcp-agent deploy` or `mcp-agent cloud servers describe` (e.g., `app_abc123xyz.deployments.mcp-agent.com`).

​

1. Find the server URL

# Show all deployments (filterable, sortable)
mcp-agent cloud servers list

# Describe a specific deployment and copy the Server URL
mcp-agent cloud servers describe app_abc123 --format text

• Server URL – base URL (append /sse for SSE transport or /call_tool for HTTP).
• Authentication mode (Bearer token, unauthenticated, OAuth coming soon).
• Status, creation time, description.

​

2. Make sure clients have the right secrets

# Prompts for required secrets (per API key)
mcp-agent cloud configure --id https://<app_id>.deployments.mcp-agent.com

# Inspect required parameters without storing
mcp-agent cloud configure --id <server-url> --params

​

3. Install into MCP clients

# Claude Desktop (macOS, Windows, Linux)
    mcp-agent install https://<app_id>.deployments.mcp-agent.com/sse \
  --client claude_desktop --name web-summarizer

# Cursor
    mcp-agent install https://<app_id>.deployments.mcp-agent.com/sse \
  --client cursor

# VS Code MCP extension
    mcp-agent install https://<app_id>.deployments.mcp-agent.com/sse \
  --client vscode

# Claude Code (codespaces experience)
    mcp-agent install https://<app_id>.deployments.mcp-agent.com/sse \
  --client claude_code

# ChatGPT Apps (requires --no-auth deployments)
    mcp-agent install https://<app_id>.deployments.mcp-agent.com/sse \
  --client chatgpt

• Validates your MCP_API_KEY (or uses --api-key).
• Fetches app metadata (name, unauthenticated status) for validation.
• Writes the appropriate JSON snippet to the client-specific config file.
• Masks secrets when printing to the terminal (use --dry-run to preview).

Client config locations:
• Claude Desktop – ~/Library/Application Support/Claude/claude_desktop_config.json (macOS)
• Cursor – ~/.cursor/mcp.json
• VS Code – <workspace>/.vscode/mcp.json
• Claude Code – ~/.claude.json

​

4. Manual configuration (if needed)

{
  "servers": {
    "web-summarizer": {
      "url": "https://<app_id>.deployments.mcp-agent.com/sse",
      "headers": {
        "Authorization": "Bearer ${MCP_API_KEY}"
      }
    }
  }
}

{
  "servers": {
    "web-summarizer": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://<app_id>.deployments.mcp-agent.com/sse",
        "--header",
        "Authorization: Bearer ${MCP_API_KEY}"
      ]
    }
  }
}

​

5. Automate calls from code

​

Python

1. Create or update a server entry in mcp_agent.config.yaml:
   mcp:
     servers:
       web_summarizer_cloud:
         transport: sse
         url: "https://<app_id>.deployments.mcp-agent.com/sse"
         headers:
           Authorization: "Bearer ${MCP_API_KEY}"
   
2. Use the shared server registry to open a client session:
   import asyncio
   from mcp_agent.config import get_settings
   from mcp_agent.mcp.mcp_server_registry import ServerRegistry
   from mcp_agent.mcp.gen_client import gen_client
   
   async def run_workflow():
       registry = ServerRegistry(config=get_settings())
       async with gen_client("web_summarizer_cloud", server_registry=registry) as client:
           launch = await client.call_tool(
               "workflows-WebSummarizerWorkflow-run",
               arguments={"run_parameters": {"url": "https://example.com"}},
           )
           run_id = launch.content[0].text
           status = await client.call_tool(
               "workflows-get_status",
               arguments={"run_id": run_id},
           )
           print(status.content[0].text)
   
   asyncio.run(run_workflow())
   

​

HTTP / cURL

curl -X POST https://<app_id>.deployments.mcp-agent.com/call_tool \
  -H "Authorization: Bearer $MCP_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "workflows-WebSummarizerWorkflow-run",
    "arguments": {"run_parameters": {"url": "https://example.com"}}
  }'

​

MCP Inspector

npx @modelcontextprotocol/inspector \
  --transport sse \
  --server-url https://<app_id>.deployments.mcp-agent.com/sse \
  --header "Authorization: Bearer $MCP_API_KEY"

​

6. Provide usage instructions to end users

• The server URL and description.
• Required user secrets (from mcp-agent cloud configure --params).
• Example calls (like the snippets above).
• Recommended MCP clients (Claude Desktop, Cursor, ChatGPT, etc.).
• Observability tips (mcp-agent cloud logger tail for debugging).

​

7. Rotate tokens and access

• Rotate API keys – run mcp-agent login again or set a new MCP_API_KEY.
• Revoke access – delete individual configurations (coming soon) or redeploy with --auth to disable unauthenticated access.
• Publish publicly – ensure the deployment is unauthenticated and document explicit rate limits / expectations.
