Usage

Run with your existing MCP_CONFIG (same as used with Claude, Cursor, etc.):

export MCP_CONFIG='{"mcpServers":{"server1":{"command":"python","args":["server.py"]}}}'
tl --use-policy block_pii_in_tool_args

Or with Docker:

docker run -e MCP_CONFIG='{"mcpServers":{"server1":{"command":"python","args":["server.py"]}}}' \
  ghcr.io/codeintegrity-ai/tramlines-gateway:latest uv run tl --use-policy block_pii_in_tool_args

Advanced Usage

For custom policies, use --policy-path to load your own policy file:

tl --policy-path /path/to/your/custom_policy.py

With Docker (mount your policy file):

docker run -v /path/to/your/policy.py:/app/policy.py \
  -e MCP_CONFIG='{"mcpServers":{"server1":{"command":"python","args":["server.py"]}}}' \
  ghcr.io/codeintegrity-ai/tramlines-gateway:latest uv run tl --policy-path /app/policy.py
