AI agents and MCP servers
Scaffold an MCP server, convert an OpenAPI spec into MCP tools, and test tool calls before an agent makes them. Then decide what an agent may do: audit permissions, map the blast radius of each tool, compile approval rules and read the traces when a run goes wrong.

AI tools
AI Tool Schema Builder
Build AI tool definitions in a visual editor with typed, enum and nested parameters, and export them as OpenAI, Anthropic, MCP or JSON Schema.
AI tools
Function Call Flow Simulator

AI tools
Tool Approval Matrix Compiler
Compile cross-platform allow, ask, and deny decisions for tool capabilities across Codex, Claude, and managed MCP policies
AI tools
Agent Trace Viewer
Inspect AI agent traces from LangChain runs, OpenAI Assistants run steps or a JSON step array, with LLM calls, tool calls, errors, timings and tokens.
AI tools
Trace Failure Classifier
Classify failed trace events into root-cause buckets and output deterministic remediation guidance for agent incident triage
AI tools
