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 both `stdio` and SSE transport. - 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, it will use `stdio` transport. If you want to use SSE, use flag `--transport sse`. - If you want to debug, use `RUST_LOG=info`. - If you're loading unsigned OCI plugin, you need to set `insecure_skip_signature` to `true` in your config file. ## 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:  ## 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/github): 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 & retrieve memory, powered by SQLite (Rust) - [sqlite](https://github.com/tuananh/hyper-mcp/tree/main/examples/plugins/sqlite): 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) - [gitlab](https://github.com/tuananh/hyper-mcp/tree/main/examples/plugins/gitlab): GitLab plugin (Rust) - [meme-generator](https://github.com/tuananh/hyper-mcp/tree/main/examples/plugins/meme-generator): Meme generator (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 && \ 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 ``` ## License [Apache 2.0](./LICENSE) ## Star History [](https://www.star-history.com/#tuananh/hyper-mcp&Date) ", Assign "at most 3 tags" to the expected json: {"id":"13451","tags":[]} "only from the tags list I provide: [{"id":77,"name":"3d"},{"id":89,"name":"agent"},{"id":17,"name":"ai"},{"id":54,"name":"algorithm"},{"id":24,"name":"api"},{"id":44,"name":"authentication"},{"id":3,"name":"aws"},{"id":27,"name":"backend"},{"id":60,"name":"benchmark"},{"id":72,"name":"best-practices"},{"id":39,"name":"bitcoin"},{"id":37,"name":"blockchain"},{"id":1,"name":"blog"},{"id":45,"name":"bundler"},{"id":58,"name":"cache"},{"id":21,"name":"chat"},{"id":49,"name":"cicd"},{"id":4,"name":"cli"},{"id":64,"name":"cloud-native"},{"id":48,"name":"cms"},{"id":61,"name":"compiler"},{"id":68,"name":"containerization"},{"id":92,"name":"crm"},{"id":34,"name":"data"},{"id":47,"name":"database"},{"id":8,"name":"declarative-gui "},{"id":9,"name":"deploy-tool"},{"id":53,"name":"desktop-app"},{"id":6,"name":"dev-exp-lib"},{"id":59,"name":"dev-tool"},{"id":13,"name":"ecommerce"},{"id":26,"name":"editor"},{"id":66,"name":"emulator"},{"id":62,"name":"filesystem"},{"id":80,"name":"finance"},{"id":15,"name":"firmware"},{"id":73,"name":"for-fun"},{"id":2,"name":"framework"},{"id":11,"name":"frontend"},{"id":22,"name":"game"},{"id":81,"name":"game-engine "},{"id":23,"name":"graphql"},{"id":84,"name":"gui"},{"id":91,"name":"http"},{"id":5,"name":"http-client"},{"id":51,"name":"iac"},{"id":30,"name":"ide"},{"id":78,"name":"iot"},{"id":40,"name":"json"},{"id":83,"name":"julian"},{"id":38,"name":"k8s"},{"id":31,"name":"language"},{"id":10,"name":"learning-resource"},{"id":33,"name":"lib"},{"id":41,"name":"linter"},{"id":28,"name":"lms"},{"id":16,"name":"logging"},{"id":76,"name":"low-code"},{"id":90,"name":"message-queue"},{"id":42,"name":"mobile-app"},{"id":18,"name":"monitoring"},{"id":36,"name":"networking"},{"id":7,"name":"node-version"},{"id":55,"name":"nosql"},{"id":57,"name":"observability"},{"id":46,"name":"orm"},{"id":52,"name":"os"},{"id":14,"name":"parser"},{"id":74,"name":"react"},{"id":82,"name":"real-time"},{"id":56,"name":"robot"},{"id":65,"name":"runtime"},{"id":32,"name":"sdk"},{"id":71,"name":"search"},{"id":63,"name":"secrets"},{"id":25,"name":"security"},{"id":85,"name":"server"},{"id":86,"name":"serverless"},{"id":70,"name":"storage"},{"id":75,"name":"system-design"},{"id":79,"name":"terminal"},{"id":29,"name":"testing"},{"id":12,"name":"ui"},{"id":50,"name":"ux"},{"id":88,"name":"video"},{"id":20,"name":"web-app"},{"id":35,"name":"web-server"},{"id":43,"name":"webassembly"},{"id":69,"name":"workflow"},{"id":87,"name":"yaml"}]" returns me the "expected json"
