sst-streaming-http-mcp-server

This is an SST monorepo that deploys an AWS Lambda and Cloudfront distribution for MCP streaming HTTP servers. Currently this doesn't include auth.

Setup

• Recommended: Follow the SST guide to set up your AWS org/accounts
• Use .env.example to create your own .env file
• bun install
• bun dev to launch SST dev mode
• bun deploy to deploy

Using MCP Inspector (@modelcontextprotocol/inspector)

• bun dev to launch SST dev mode
• bun mcp-inspect to launch MCP Inspector
• Launch the UI in the browser at http://127.0.0.1:6274
• Select Transport Type: Streamable HTTP
• Input the URL to the MCP server
  • This will be the URL of the API Router that you deployed, displayed in bun dev output.
  • Append the proper routing to the /mcp endpoint: {CLOUDFRONT_URL_FROM_SST}/mcp/test-server/mcp

Coding style

• Ensure bun typecheck and bun check pass. You can run bun fix to format the code.
  • To use the git hooks in the repo's .githooks folder, which will save you from waiting for CI to tell you that you forgot to these commands, run this:

    git config core.hookspath .githooks
