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.

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.

- 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

- oci://- for OCI-compliant registries (like Docker Hub, GitHub Container Registry, etc.)
- file://- for local files
- http://orhttps://- for remote files
- s3://- for Amazon S3 objects (requires that you have your AWS credentials set up in the environment)

- By default, it will usestdiotransport. If you want to use SSE, use flag--transport sseor streamable HTTP with--transport streamable-http.
- If you want to debug, useRUST_LOG=info.
- If you're loading unsigned OCI plugin, you need to setinsecure_skip_signatureflag or env varHYPER_MCP_INSECURE_SKIP_SIGNATUREtotrue

You can configure hyper-mcp either globally for all projects or specifically for individual projects.
- For project-scope configuration, create.cursor/mcp.jsonin your project root:

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

Set up hyper-mcp in Cursor's settings:

We maintain several example plugins to get you started:

These plugins use the v1 plugin interface. While still supported, new plugins should use the v2 interface.

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