# 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
- Sanboxing with WASM: ability to limit network, filesystem, memory access
- 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
- Support tool name prefix to prevent tool names collision
## 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": {
"time": {
"url": "oci://ghcr.io/tuananh/time-plugin:latest"
},
"qr-code": {
"url": "oci://ghcr.io/tuananh/qrcode-plugin:latest"
},
"hash": {
"url": "oci://ghcr.io/tuananh/hash-plugin:latest"
},
"myip": {
"url": "oci://ghcr.io/tuananh/myip-plugin:latest",
"runtime_config": {
"allowed_hosts": ["1.1.1.1"]
}
},
"fetch": {
"url": "oci://ghcr.io/tuananh/fetch-plugin:latest",
"runtime_config": {
"allowed_hosts": ["*"],
"memory_limit": "100 MB",
}
}
}
}
```
> 📖 **For detailed configuration options including authentication setup, runtime configuration, and advanced features, see [RUNTIME_CONFIG.md](./RUNTIME_CONFIG.md)**
Supported URL schemes:
- `oci://` - for OCI-compliant registries (like Docker Hub, GitHub Container Registry, etc.)
- `file://` - for local files
- `http://` or `https://` - for remote files
- `s3://` - for Amazon S3 objects (requires that you have your AWS credentials set up in the environment)
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
1. Install the [XTP CLI](https://docs.xtp.dylibso.com/docs/cli):
```sh
curl https://static.dylibso.com/cli/install.sh -s | bash
```
2. Create a new plugin project:
```sh
xtp plugin init --schema-file plugin-schema.yaml
```
Follow the prompts to set up your plugin. This will create the necessary files and structure.
For example, if you chose Rust as the language, it will create a `Cargo.toml`, `src/lib.rs` and a `src/pdk.rs` file.
3. Implement your plugin logic in the language appropriate files(s) created (e.g. - `Cargo.toml` and `src/lib.rs` for Rust)
For example, if you chose Rust as the language you will need to update the `Cargo.toml` and `src/lib.rs` files.
Be sure to modify the `.gitignore` that is created for you to allow committing your `Cargo.lock` file.
Check out our [example plugins](https://github.com/tuananh/hyper-mcp/tree/main/examples/plugins) for insight.
To publish a plugin:
```dockerfile

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
