A MCP proxy server that filters tools from upstream MCP servers via regex-based deny list. It acts as an intermediary, applying a deny-list to incoming tools and exposing a filtered tool set to clients. Designed for integration in catalogs and tooling pipelines.
🛠️ Key Features
- Regex-based deny list to filter tools from upstream MCP servers
- Proxy behavior between MCP upstreams and downstream clients
- Lightweight, focused on tool-level filtering
- Descriptive readme excerpt aligned with repository metadata
🚀 Use Cases
- Catalogs that aggregate MCP tools while excluding unwanted entries
- Pre-filtering MCP results before display or distribution
- Lightweight middleware for tool governance in MCP ecosystems
⚡ Developer Benefits
- Clear ground-truth for filtering logic via regex rules
- Simple integration point between MCP servers and consumer apps
- DNS and routing agnostic proxy behavior for flexible deployment
- Readme excerpt provides quick context for new contributors
⚠️ Limitations
- Filtering relies on regex accuracy; false positives/negatives possible
- Behavior depends on upstream MCP server responses
- Minimal feature scope: tool filtering only, no full MCP protocol emulation
