# 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:

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
