PMCP Server

An MCP server that exposes PMCP SDK capabilities as tools, resources, and prompts — enabling AI coding assistants to test, scaffold, and reference PMCP documentation through the MCP protocol.

Deploy to the cloud

The PMCP server uses stateless streamable HTTP — pure HTTP POST/response with no WebSocket or long-lived connections — making it ideal for serverless deployment. Both options below operate well within their free tiers for low-traffic usage.

AWS Lambda

Deploy as a native ARM64 binary behind API Gateway using CDK:

# Prerequisites
cargo install cargo-lambda
npm install -g aws-cdk

# Initialize and deploy
cargo pmcp deploy init --target aws-lambda --region us-east-1
cargo pmcp deploy --target aws-lambda

This compiles the server to aarch64-unknown-linux-musl, wraps it with a Lambda adapter that translates API Gateway events to HTTP, and provisions the stack via CloudFormation. The free tier includes 1M requests/month and 400K GB-seconds.

After deployment, get your endpoint:

cargo pmcp deploy outputs --target aws-lambda

Then configure your AI client to use the deployed URL instead of localhost.

Google Cloud Run

Deploy as a container to Google's managed serverless platform:

# Prerequisites
# Install Docker: https://docs.docker.com/get-docker/
# Install gcloud: https://cloud.google.com/sdk/docs/install
gcloud auth login

# Initialize and deploy
cargo pmcp deploy init --target google-cloud-run
cargo pmcp deploy --target google-cloud-run

This builds a Docker image with the server binary, pushes it to Google Container Registry, and deploys to Cloud Run. The free tier includes 2M requests/month and 360K GB-seconds.

Managing deployments

# View logs
cargo pmcp deploy logs --target aws-lambda --tail

# Run health check
cargo pmcp deploy test --target aws-lambda

# Tear down
cargo pmcp deploy destroy --target aws-lambda --clean
