MCP Sync Check

Check MCP server ↔ bash source sync

The MCP server hardcodes data that's also defined in bash. Drift breaks AI tool suggestions silently.

What's mirrored

Run the validator

python3 scripts/validate_mcp_sync.py

Output:

• ✅ 0 errors → both sides match. Done.
• ❌ Mismatches → fix the Python side to match bash (bash is the source of truth).

When you've edited bash → mirror to Python

Added a new Docker image

lib/installers.sh → ALL_DOCKER_IMAGES+=("img|label") → mcp_server/tools_db.py → add to DOCKER_IMAGES dict.

Added a new pipx tool with mismatched binary name

scripts/verify.sh → _PIPX_BIN_NAMES["pypi-name"]="bin-name" → mcp_server/tools_db.py → add to PIPX_BIN_NAMES dict.

Added a new module

lib/common.sh → MODULE_DESCRIPTIONS["mod"]="desc" → mcp_server/tools_db.py → add to MODULE_DESCRIPTIONS dict.

Added a new profile

profiles/myprof.conf → set PROFILE_DESC and MODULES → mcp_server/profiles.py → add to PROFILES dict with same modules list.

When you've edited Python → mirror to bash

This is rare and usually wrong. Bash is the source of truth. If a tool is only known to MCP, the install side won't be able to install it. Fix bash first, then mirror.

After fixing

Re-run:

python3 scripts/validate_mcp_sync.py
cd mcp_server && uv run --group dev pytest tests/ -q

Both must pass.
