Crabeye MCP Bridge Overview

crabeye-mcp-bridge MCP server places a single STDIO endpoint between an AI assistant and multiple upstream MCP servers. It exposes only `search_tools` and `run_tool`, keeping upstream schemas out of the context window until a tool search is performed. Upstreams can use STDIO, HTTP, or SSE, with namespacing, fuzzy discovery, credentials, and per-tool execution policies. Reach for it when many MCP connections create excessive tool-schema context or when centralized execution controls are needed.

Primary Use Cases for Crabeye MCP Bridge:
  • Consolidate many MCP servers behind one assistant connection
  • Search a large tool catalog before loading tool schemas
  • Require approval for selected upstream tools
  • Store upstream credentials outside plain-text configuration
