# hyper-mcp
A fast, secure MCP server that extends its capabilities through WebAssembly plugins.
## What is it?
hyper-mcp makes it easy to add AI capabilities to your applications. It works with Claude Desktop, Cursor IDE, and other MCP-compatible apps. Write plugins in your favorite language, distribute them through container registries, and run them anywhere - from cloud to edge.
## Features
- Write plugins in any language that compiles to WebAssembly
- Distribute plugins via standard OCI registries (like Docker Hub)
- Built on [Extism](https://github.com/extism/extism) for rock-solid plugin support
- Lightweight enough for resource-constrained environments
- Support all 3 protocols in the spec: `stdio`, `sse` and `streamble-http`.
- Deploy anywhere: serverless, edge, mobile, IoT devices
- Cross-platform compatibility out of the box
## Security
Built with security-first mindset:
- Sandboxed plugins that can't access your system without permission
- Memory-safe execution with resource limits
- Secure plugin distribution through container registries
- Fine-grained access control for host functions
- OCI plugin images are signed at publish time and verified at load time with [sigstore](https://www.sigstore.dev/).
## Getting Started
1. Create your config file:
- Linux: `$HOME/.config/hyper-mcp/config.json`
- Windows: `{FOLDERID_RoamingAppData}`. Eg: `C:\Users\Alice\AppData\Roaming`
- macOS: `$HOME/Library/Application Support/hyper-mcp/config.json`
```json
{
"plugins": [
{
"name": "time",
"path": "oci://ghcr.io/tuananh/time-plugin:latest"
},
{
"name": "qr-code",
"path": "oci://ghcr.io/tuananh/qrcode-plugin:latest"
},
{
"name": "hash",
"path": "oci://ghcr.io/tuananh/hash-plugin:latest"
},
{
"name": "myip",
"path": "oci://ghcr.io/tuananh/myip-plugin:latest",
"runtime_config": {
"allowed_hosts": ["1.1.1.1"]
}
},
{
"name": "fetch",
"path": "oci://ghcr.io/tuananh/fetch-plugin:latest",
"runtime_config": {
"allowed_hosts": ["*"],
"memory_limit": "100 MB"
}
}
]
}
```
2. Start the server:
```sh
$ hyper-mcp
```
- By default, it will use `stdio` transport. If you want to use SSE, use flag `--transport sse` or streamable HTTP with `--transport streamable-http`.
- If you want to debug, use `RUST_LOG=info`.
- If you're loading unsigned OCI plugin, you need to set `insecure_skip_signature` flag or env var `HYPER_MCP_INSECURE_SKIP_SIGNATURE` to `true`
## Using with Cursor IDE
You can configure hyper-mcp either globally for all projects or specifically for individual projects.
1. For project-scope configuration, create `.cursor/mcp.json` in your project root:
```json
{
"mcpServers": {
"hyper-mcp": {
"command": "/path/to/hyper-mcp"
}
}
}
```
2. Set up hyper-mcp in Cursor's settings:
3. Start using tools through chat:

## Creating Plugins
Check out our [example plugins](https://github.com/tuananh/hyper-mcp/tree/main/examples/plugins) to learn how to build your own.
To publish a plugin:
```dockerfile
# example how to build with rust
FROM rust:1.86-slim AS builder
RUN rustup target add wasm32-wasip1 && \
rustup component add rust-std --target wasm32-wasip1 && \
cargo install cargo-auditable
WORKDIR /workspace
COPY . .
RUN cargo fetch
RUN cargo auditable build --release --target wasm32-wasip1
FROM scratch
WORKDIR /
COPY --from=builder /workspace/target/wasm32-wasip1/release/plugin.wasm /plugin.wasm
```
Then build and push:
```sh
docker build -t your-registry/plugin-name .
docker push your-registry/plugin-name
