MCP Debugger

# mcp-debugger-wrapper.sh @source-hash: 65455119cf7b045d @generated: 2026-02-10T00:42:00Z ## Primary Purpose Bash wrapper script for the mcp-debugger Node.js application that automatically handles transport mode detection and ensures proper stdio configuration for Claude Code integration. ## Core Functionality The script intelligently routes execution based on command-line arguments: - **Transport Detection Logic (L7)**: Checks if arguments are empty or lack `--transport` flag - **Stdio Mode Execution (L9)**: Automatically injects `stdio` argument when running without explicit transport - **Passthrough Mode (L12)**: Preserves original arguments for explicit transport specifications ## Key Components - **Argument Analysis (L7)**: Uses bash parameter expansion and pattern matching to detect transport mode - **Execution Delegation (L9, L12)**: Both branches use `exec` to replace shell process with Node.js runtime - **Path Resolution (L9, L12)**: Dynamically resolves script directory using `$(dirname "$0")` for portable execution ## Architectural Decisions - **Default Stdio Assumption**: Assumes Claude Code integration requires stdio mode when no transport specified - **Process Replacement**: Uses `exec` instead of subprocess calls to maintain PID and signal handling - **Argument Preservation**: Maintains original argument order with `"$@"` expansion ## Dependencies - Node.js runtime (assumed available in PATH) - Compiled JavaScript distribution at `./dist/index.js` relative to wrapper location - MCP SDK stdio transport functionality ## Integration Context Designed specifically for Claude Code IDE integration where the MCP debugger needs to suppress console output and communicate via stdio transport protocol.
