Tool Registry

A Tool Registry is the catalog of external tools (functions, APIs, services) that AI agents can invoke — making capabilities discoverable, governable, and reusable. Registries store tool metadata: name, description, input schema, output schema, authentication requirements, latency expectations, cost, and access policies. When an agent receives a request, it consults the registry to discover available tools and select appropriate ones. The Model Context Protocol (MCP), introduced by Anthropic in late 2024 and gaining broad adoption in 2025, standardizes how tools are registered and discovered across AI platforms. Other registry approaches include OpenAI's function-calling registry pattern, LangChain's tool collections, LlamaIndex tools, and various enterprise registries. Effective registries enable safe tool sharing across teams, prevent duplicate tool development, and provide governance over what AI agents can do. AI governance, AI compliance, and AI risk management programs depend on tool registries to control agent behavior — supporting responsible AI through visible, governable tool access across enterprise AI agent deployments.

Centralpoint Is a Local Tool Registry for AI Agents: Oxcyon's Centralpoint AI Governance Platform catalogs every tool and skill, exposes them to OpenAI, Gemini, Llama, and embedded models, and meters every invocation. Centralpoint keeps prompts and skills on-prem and embeds tool-driven chatbots into your portals via a single JavaScript line.
