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 for rock-solid plugin support
- Lightweight enough for resource-constrained environments
- 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
Getting Started
- 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
- Linux:
{
"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": ["*"]
}
}
]
}
- Start the server:
$ hyper-mcp
By default, logs will go into state_dir on Linux or data_local_dir on macOS & Windows.
Platform | Value | Example |
---|---|---|
Linux | $XDG_DATA_HOME or $HOME/.local/share |
/home/alice/.local/share |
macOS | $HOME/Library/Application Support |
/Users/Alice/Library/Application Support |
Windows | {FOLDERID_LocalAppData} |
C:\Users\Alice\AppData\Local |
Using with Cursor IDE
You can configure hyper-mcp either globally for all projects or specifically for individual projects.
- For project-scope configuration, create
.cursor/mcp.json
in your project root:
{
"mcpServers": {
"hyper-mcp": {
"command": "/path/to/hyper-mcp",
"args": [""]
}
}
}
-
Set up hyper-mcp in Cursor's settings:

Creating Plugins
Check out our example plugins to learn how to build your own.
To publish a plugin:
# 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
WORKDIR /workspace
COPY . .
RUN cargo fetch
RUN cargo build --release --target wasm32-wasip1
# copy wasm to final image
FROM scratch
WORKDIR /
COPY --from=builder /workspace/target/wasm32-wasip1/release/your-plugin.wasm /plugin.wasm
Then build and push:
docker build -t your-registry/plugin-name .
docker push your-registry/plugin-name
