Field notes
The page compares five coding tools across a matrix of MCP capabilities, using Yes, No, and Partial rather than treating support as binary. Its notes distinguish protocol-level features from similarly named product features—for example, MCP Tasks versus a tool’s own background jobs or subagents. The table references protocol revisions through 2026-07-28 and covers implementation details such as elicitation modes, stdio negotiation, deferred schemas, and tools/list pagination.
