⚠️ NOTICE: PROJECT TRANSFERRED

This project has been transferred to [https://github.com/joseph-wortmann/hyper-mcp](https://github.com/joseph-wortmann/hyper-mcp)

Please refer to the new repository for the latest updates and contributions.

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
• Sanboxing with WASM: ability to limit network, filesystem, memory access
• 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
• 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.

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

{

"plugins": { "time": { "url": "oci://ghcr.io/tuananh/time-plugin:latest" }, "qr_code": { "url": "oci://ghcr.io/tuananh/qrcode-plugin:latest" }, "hash": { "url": "oci://ghcr.io/tuananh/hash-plugin:latest" }, "myip": { "url": "oci://ghcr.io/tuananh/myip-plugin:latest", "runtime_config": { "allowed_hosts": ["1.1.1.1"] } }, "fetch": { "url": "oci://ghcr.io/tuananh/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.)
• 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)

1. Start the server:

$ 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:

{

"mcpServers": { "hyper-mcp": { "command": "/path/to/hyper-mcp" } } }

1. Set up hyper-mcp in Cursor's settings:

1. 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: Get current time and do time calculations (Rust)
• qr_code: Generate QR codes (Rust)
• hash: Generate various types of hashes (Rust)
• myip: Get your current IP (Rust)
• fetch: Basic webpage fetching (Rust)
• crypto_price: Get cryptocurrency prices (Go)
• fs: File system operations (Rust)
• github: GitHub plugin (Go)
• eval_py: Evaluate Python code with RustPython (Rust)
• arxiv: Search & download arXiv papers (Rust)
• memory: Let you store & retrieve memory, powered by SQLite (Rust)
• sqlite: Interact with SQLite (Rust)
• crates-io: Get crate general information, check crate latest version (Rust)
• gomodule: Get Go modules info, version (Rust)
• qdrant: keeping & retrieving memories to Qdrant vector search engine (Rust)
• gitlab: GitLab plugin (Rust)
• meme_generator: Meme generator (Rust)
• context7: Lookup library documentation (Rust)
• think: Think tool(Rust)
• maven: Maven plugin (Rust)
• serper: Serper web search plugin (Rust)

V2 Plugins

These plugins use the v2 plugin interface. New plugins should use this interface.

• rstime: Get current time and do time calculations (Rust)

Community-built plugins

• hackernews: 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: This plugin retrieves project ID from release-monitoring.org, which helps track versions of released software.
• yahoo-finance: This plugin connects to the Yahoo Finance API to provide stock prices (OHLCV) based on a company name or ticker symbol.
• rand16: This plugen generates random 16 bytes buffer and provides it in base64uri format - very usable for symmetric cryptography online.
