Mcpward

Mcpward: Security and contract testing tool for Model Context Protocol servers.

Mcpward performs contract testing for Model Context Protocol servers in continuous integration pipelines. It treats an MCP server like an external dependency by snapshotting its contract and failing the build when changes occur. The tool catches schema drift, altered tool descriptions, protocol violations, error-contract mistakes, and tool-poisoning patterns. It runs locally without accounts, API calls, or telemetry. It classifies changes as breaking or non-breaking and supports console, JSON, JUnit, SARIF, and Markdown reporting.
