File Convert MCP Server is a Model Context Protocol server that lets AI assistants and agent workflows handle file conversion tasks on demand. By exposing conversion capabilities through MCP, it allows tools like Claude, Cursor, or custom agents to transform documents, images, audio, and other file types without manual intervention. The server is designed to be format-agnostic, routing requests to the appropriate conversion logic based on input and target type. This makes it suitable for automating document pipelines, preparing assets, or normalizing data formats inside larger agentic systems.

• MCP-compliant server interface
• Multi-format file conversion support
• Works with documents, images, audio, and more
• Agent-friendly tool definitions
• Local execution for file privacy
• Composable with other MCP servers

OracleNet by ToolOracle is an infrastructure layer designed for autonomous AI agents that need to discover, verify, and transact with external tools and services. It aggregates 98 MCP (Model Context Protocol) servers and roughly 1,147 tools into a unified mesh, handling identity, policy, and settlement so agents can act without bespoke integrations for each provider. The platform focuses on three pillars: compliance checks that gate which tools an agent may invoke, trust signals that help agents evaluate tool reliability, and settlement rails that resolve usage, billing, and audit trails. This makes it suitable for teams deploying agent fleets in regulated or multi-vendor environments where accountability matters. Because OracleNet sits between agents and the broader tool ecosystem, it is best understood as middleware rather than an end-user product, and value depends on the breadth and quality of the connected MCP catalog.

• Unified access to 98 MCP servers
• Directory of ~1,147 connected tools
• Compliance and policy gating for agent actions
• Trust scoring across tool providers
• Settlement and billing reconciliation
• Audit logging for agent activity
