Walkthrough

The codebase was refactored to move CrateDB interaction tools from __main__.py into a new tool.py module, with updated tool registration using imported functions. The CLI was extended to support an "http" transport and new --host and --path options. The FastMCP dependency was upgraded to version 2.10, and tests and documentation were updated accordingly.

Changes

File(s)	Summary
CHANGES.md, README.md	Updated changelog and documentation to reflect FastMCP 2.10 upgrade, new CLI options --host and --path, and transport naming updates.
cratedb_mcp/main.py	Refactored to remove inline tool implementations; replaced with imports from tool.py and registered tools via mcp.add_tool.
cratedb_mcp/tool.py	New module added with functions for querying CrateDB health, SQL execution, metadata, and documentation fetching.
cratedb_mcp/cli.py	Added support for "http" transport; added --host and --path CLI options; updated serve function signature and logic.
pyproject.toml	Updated FastMCP dependency version constraint from <2.7 to >=2.10,<2.11.
tests/test_cli.py	Updated tests to reflect new transport "http" and additional keyword arguments in mocked mcp.run_async calls.
tests/test_mcp.py	Updated imports to use tool.py functions; renamed and adjusted health test; updated patch targets accordingly.
examples/mcptools.sh	Changed example command from get_health to get_cluster_health.

Poem

🐇 A hop, a skip, the code’s anew,
Tools moved out, fresh paths in view.
HTTP joins the transport crew,
Host and path now guide us through.
FastMCP shines in version ten,
The rabbit cheers, “Let’s code again!” 🎉🐰
