SuperQode v0.2.37 : Prepare for MCP and Stable FastMCP Harness Support
SuperQode v0.2.37 strengthens MCP support while keeping production users on the stable MCP v1 protocol line.
Highlights
- Migrated superqode mcp and superqode serve harness to standalone FastMCP 3.4.4.
- Added support for serving harnesses over stdio and Streamable HTTP.
- Added a runnable local MCP server and HarnessSpec example.
- Documented MCP serving, consumption, runtime ownership, transports, and security considerations.
- Constrained the MCP Python SDK to <2 to prevent an accidental upgrade to the prerelease protocol stack.
- Updated package, ACP registry, lockfile, and release metadata.
New MCP Spec Compatibility
This release uses:
- FastMCP 3.4.4
- MCP Python SDK >=1.27.1,<2
- stdio for local MCP servers
- Streamable HTTP for remote MCP servers
- SSE only for compatibility with legacy servers
FastMCP 4 and MCP SDK v2 will be evaluated separately once their stable compatibility path is available.
