Fullbleed 2.5.1 — MCP client compatibility

Fullbleed 2.5.1 fixes tool discovery in strict MCP clients. Every tool now declares an object at the root of its output schema, preserving the existing success and error results. Both MCP entrypoints and the generated agent contract use the corrected shared definitions.

Upgrade in the Python environment used by your MCP client, then restart the client:

python -m pip install --upgrade fullbleed fullbleed-mcp

The release adds an interoperability check using the official MCP TypeScript SDK: tool discovery, structured capabilities, PDF preview generation, and a structured tool error. The SDK is a development dependency; the Python core still has no required third-party Python runtime packages. The Rust renderer is unchanged.

Validation covers 15 platform wheels, 19 installed-wheel checks, and native watch checks on five Windows/macOS targets. The attached verification report and engineering archive retain the release checks and scoped print-profile evidence. These checks do not constitute independent ISO PDF/VT certification.
