TL;DR: AI agents can shift from hardcoded tool lists to runtime discovery, allowing them to find, select, and execute approved MCP servers as environments change, according to Kong. That improves flexibility, but it also makes tool governance, access boundaries, and registry trust the real control points for agentic systems.

Editorial analysis by NHI Mgmt Group, based on content published by Kong: “# Leveraging the MCP Registry in Kong Konnect for Dynamic Tool Discovery”.

Key questions

Q: How should teams govern MCP tools discovered during AI access onboarding?

A: Treat every discovered MCP tool as an entitlement that needs classification, approval, and ownership before use.

Q: Why does hardcoded tool configuration break down for agentic systems?

A: Because it assumes the tool set is stable long enough to be embedded in code.

Q: What are the signs that MCP registry governance is too broad?

A: If development tools appear in production discovery results, if agents can enumerate servers they should not be able to use, or if metadata is too vague to explain why a tool was visible, the registry boundary is too loose.

Practitioner guidance

  • Define registry trust boundaries Separate discovery scope from execution scope so an agent can only see the MCP servers that are valid for its environment and role.
  • Segment registries by environment Keep development, staging, and production registries distinct so experimental tools do not become discoverable in production workflows.
  • Require metadata ownership fields Populate namespace, owner, environment, and access boundary metadata for every server so discovery decisions can be audited and explained.

Bottom line: MCP registry-driven discovery changes the governance problem by making runtime visibility the new control point for AI agents.

Registry-driven discovery turns tool publication into an access decision. Once an AI agent can ask what tools exist at runtime, the registry is no longer an index. It is the policy layer that determines which capabilities are visible, in which environment, and under which ownership model. That makes registry governance a first-class identity control for agentic systems, not a convenience feature.

A few things that frame the scale:

  • 24,008 unique secrets were exposed in MCP configuration files in 2025 alone, the protocol's first year of widespread adoption, according to the State of Secrets Sprawl 2026.

A question worth separating out:

Q: How do teams decide which MCP servers an agent should be allowed to discover?

A: Start from business role, environment, and ownership, then restrict discovery to the smallest approved capability set that supports the task. Discovery should be narrower than the full catalog, because visibility itself creates risk.
