Anthropic-backed MCP bridge connects cloud agents to local tools
Cloud AI agents now access local files via MCP bridge with WebSocket relays
Deep Dive
An MCP bridge lets Amazon Bedrock AgentCore cloud agents reach local MCP servers, using WebSocket and native messaging to relay tool calls. The post recreates, in simplified open-source form, an internal finance AI assistant that handled over 41,000 conversations in its first year. The demo shows a browser extension summarizing a local Excel workbook through the bridge.
Key Points
- MCP Bridge enables cloud agents to call local tools via WebSocket-to-native-messaging relay
- Demo uses Amazon Bedrock AgentCore + Strands agent + local MCP server (e.g., Excel reader) with stdio transport
- 41K+ production conversations handled; full source on GitHub with architecture for secure file access
Why It Matters
Lets cloud-based AI agents securely analyze sensitive local files without file uploads or manual export.
