> witnessd-mcp — jschunter-witnessd-mcp. Use this tool when you need to create tamper-evident records of online content or API responses, as it enables agents to generate signed and Merkle-anchored certificates of public URLs or API responses at a specific moment in time, solving problems related to data integrity and authenticity. It takes public URLs or API responses as input and produces certificates as output. Ideal for use cases requiring immutable proof of data existence or state at a given time.
