AlicenseAqualityDmaintenanceEnables conversion of files, HTML, and Markdown to PDF through natural language, using the FileToPDF API.4752MITWhy this server?
Adapter for CrewAI to coordinate shared state and prevent lost updates or stale reads across agents.
AlicenseAqualityBmaintenanceCoherence guard for shared files: when two agents write the same file, the stale writer is denied instead of silently overwriting, then reacquires and retries. Single-host, TLA+-verified.512Apache 2.0Why this server?
Drop-in tools for CrewAI, exposing functions to check reputation, submit ratings, and list services.
AlicenseAqualityAmaintenanceA free, open reputation registry for AI microservices: check a service's trust score before calling it and submit a rating afterward. Ratings can be backed by cryptographic receipts signed by the service and are recorded in a verifiable Merkle audit log.3Apache 2.0Why this server?
Enables CrewAI agents to manage treasury operations, including balance inquiries, transfers, and spending limits, through MCP tools.
