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 `stdio` transport protocol - 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/hyper-mcp-rs/time-plugin:latest" }, "qr_code": { "url": "oci://ghcr.io/hyper-mcp-rs/qrcode-plugin:latest" }, "hash": { "url": "oci://ghcr.io/hyper-mcp-rs/hash-plugin:latest" }, "myip": { "url": "oci://ghcr.io/hyper-mcp-rs/myip-plugin:latest", "runtime_config": { "allowed_hosts": ["1.1.1.1"] } }, "fetch": { "url": "oci://ghcr.io/hyper-mcp-rs/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.) **REQUIRES COSIGN** - `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 ``` - Uses `stdio` transport protocol. - If you want to debug, use `RUST_LOG=debug`. - 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:  ## Available Plugins We maintain several example plugins to get you started: ### V1 Plugins These plugins use the v1 plugin interface. While still supported, new plugins should use the v2 interface. - [time](https://github.com/hyper-mcp-rs/time-plugin): Get current time and do time calculations (Rust) - [qr_code](https://github.com/hyper-mcp-rs/qr-code-plugin): Generate QR codes (Rust) - [hash](https://github.com/hyper-mcp-rs/hash-plugin): Generate various types of hashes (Rust) - [myip](https://github.com/hyper-mcp-rs/myip-plugin): Get your current IP (Rust) - [fetch](https://github.com/hyper-mcp-rs/fetch-plugin): Basic webpage fetching (Rust) - [crypto_price](https://github.com/hyper-mcp-rs/crypto-price-plugin): Get cryptocurrency prices (Go) - [fs](https://github.com/hyper-mcp-rs/fs-plugin): File system operations (Rust) - [github](https://github.com/hyper-mcp-rs/github-plugin): GitHub plugin (Go) - [eval_py](https://github.com/hyper-mcp-rs/eval-py-plugin): Evaluate Python code with RustPython (Rust) - [arxiv](https://github.com/hyper-mcp-rs/arxiv-plugin): Search & download arXiv papers (Rust) - [memory](https://github.com/hyper-mcp-rs/memory-plugin): Let you store & retrieve memory, powered by SQLite (Rust) - [sqlite](https://github.com/hyper-mcp-rs/sqlite-plugin): Interact with SQLite (Rust) - [crates-io](https://github.com/hyper-mcp-rs/crates-io-plugin): Get crate general information, check crate latest version (Rust) - [gomodule](https://github.com/hyper-mcp-rs/gomodule-plugin): Get Go modules info, version (Rust) - [qdrant](https://github.com/hyper-mcp-rs/qdrant-plugin): keeping & retrieving memories to Qdrant vector search engine (Rust) - [gitlab](https://github.com/hyper-mcp-rs/gitlab-plugin): GitLab plugin (Rust) - [meme_generator](https://github.com/hyper-mcp-rs/meme-generator-plugin): Meme generator (Rust) - [context7](https://github.com/hyper-mcp-rs/context7-plugin): Lookup library documentation (Rust) - [think](https://github.com/hyper-mcp-rs/think-plugin): Think tool(Rust) - [maven](https://github.com/hyper-mcp-rs/maven-plugin): Maven plugin (Rust) - [serper](https://github.com/hyper-mcp-rs/serper-plugin): Serper web search plugin (Rust) ### V2 Plugins These plugins use the v2 plugin interface. New plugins should use this interface. - [rstime](https://github.com/hyper-mcp-rs/rstime-plugin): Get current time and do time calculations (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. - [rand16](https://github.com/dabevlohn/rand16): This plugen generates random 16 bytes buffer and provides it in base64uri format - very usable for symmetric cryptography online. ## Documentation - **[Runtime Configuration Guide](./RUNTIME_CONFIG.md)** - Comprehensive guide to configuration options including: - Authentication setup (Basic, Token, and Keyring) - Plugin runtime configuration - Security considerations and best practices - Platform-specific keyring setup for macOS, Linux, and Windows - Troubleshooting authentication issues - **[Skip Tools Pattern Guide](./SKIP_TOOLS_GUIDE.md)** - Comprehensive guide to filtering tools using regex patterns: - Pattern syntax and examples - Common use cases and best practices - Environment-specific filtering strategies - Advanced regex techniques - Migration and troubleshooting ## Creating Plugins For comprehensive instructions on creating plugins, see [CREATING_PLUGINS.md](./CREATING_PLUGINS.md).
