# 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 - 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": ["*"] } } ] } ``` 2. Start the server: ```sh $ hyper-mcp ``` By default, logs will go into [state_dir](https://docs.rs/dirs/6.0.0/dirs/fn.state_dir.html) on Linux or [data_local_dir](https://docs.rs/dirs/6.0.0/dirs/fn.data_local_dir.html) 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` | If you're loading unsigned OCI plugin, you will need to use `--insecure-skip-signature` flag. ## 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", "args": [""] } } } ``` 2. Set up hyper-mcp in Cursor's settings: ![cursor mcp](./assets/cursor-mcp.png) 3. Start using tools through chat: ![cursor mcp chat](./assets/cursor-mcp-1.png) ## Available Plugins We maintain several example plugins to get you started: - [time](https://github.com/tuananh/hyper-mcp/tree/main/examples/plugins/time): Get current time and do time calculations (Rust) - [qr-code](https://github.com/tuananh/hyper-mcp/tree/main/examples/plugins/qr-code): Generate QR codes (Rust) - [hash](https://github.com/tuananh/hyper-mcp/tree/main/examples/plugins/hash): Generate various types of hashes (Rust) - [myip](https://github.com/tuananh/hyper-mcp/tree/main/examples/plugins/myip): Get your current IP (Rust) - [fetch](https://github.com/tuananh/hyper-mcp/tree/main/examples/plugins/fetch): Basic webpage fetching (Rust) - [crypto-price](https://github.com/tuananh/hyper-mcp/tree/main/examples/plugins/crypto-price): Get cryptocurrency prices (Go) - [fs](https://github.com/tuananh/hyper-mcp/tree/main/examples/plugins/fs): File system operations (Rust) - [github](https://github.com/tuananh/hyper-mcp/tree/main/examples/plugins/fs): GitHub plugin (Go) - [eval-py](https://github.com/tuananh/hyper-mcp/tree/main/examples/plugins/eval-py): Evaluate Python code with RustPython (Rust) - [arxiv](https://github.com/tuananh/hyper-mcp/tree/main/examples/plugins/arxiv): Search & download arXiv papers (Rust) - [memory](https://github.com/tuananh/hyper-mcp/tree/main/examples/plugins/memory): Let you store & retrive memory, powered by SQLite (Rust) - [sqlite](https://github.com/tuananh/hyper-mcp/tree/main/examples/plugins/memory): Interact with SQLite (Rust) - [crates-io](https://github.com/tuananh/hyper-mcp/tree/main/examples/plugins/crates-io): Get crate general information, check crate latest version (Rust) - [gomodule](https://github.com/tuananh/hyper-mcp/tree/main/examples/plugins/gomodule): Get Go modules info, version (Rust) - [qdrant](https://github.com/tuananh/hyper-mcp/tree/main/examples/plugins/qdrant): keeping & retrieving memories to Qdrant vector search engine (Rust) ### Community-built plugins - [hackernews](https://github.com/hungran/hyper-mcp-hackernews-tool): This plugin connects to the Hacker News API to fetch the current top stories and display them with their titles, scores, authors, and URLs. - [release-monitor-id](https://github.com/ntheanh201/hyper-mcp-release-monitor-id-tool): This plugin retrieves project ID from release-monitoring.org, which helps track versions of released software. - [yahoo-finance](https://github.com/phamngocquy/hyper-mcp-yfinance): This plugin connects to the Yahoo Finance API to provide stock prices (OHLCV) based on a company name or ticker symbol. ## 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 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: ```sh docker build -t your-registry/plugin-name . docker push your-registry/plugin-name ``` ## License [Apache 2.0](./LICENSE) ## Star History [![Star History Chart](https://api.star-history.com/svg?repos=tuananh/hyper-mcp&type=Date)](https://www.star-history.com/#tuananh/hyper-mcp&Date)
