Get plugin config schema

kong_plugin_schema

Retrieve the configuration schema for a Kong plugin to learn valid config fields, types, and defaults before creating or updating the plugin.

Instructions

Fetch the configuration schema for a plugin (GET /schemas/plugins/). Use this before creating/updating a plugin to learn the valid config fields and their types/defaults. Example name: 'rate-limiting', 'key-auth', 'cors', 'jwt', 'acl'.

Input Schema

NameRequiredDescriptionDefault
nameYesPlugin name, e.g. 'rate-limiting'.
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Describes the GET request and return of schema, implying read-only behavior. No annotations provided, so the description carries full burden; it could explicitly state it's non-destructive or safe.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences with front-loaded action and essential usage context. No extraneous information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with one parameter and no output schema, the description answers what, when, and how. Complete and self-contained.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The single parameter 'name' is described with examples, adding context beyond the schema type/required. Schema description coverage is 100%, but description provides useful example values.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states it fetches the configuration schema for a plugin, specifies HTTP method and path, and gives example plugin names. Distinguishes from sibling tools like kong_get which fetch plugin instances.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly says to use before creating/updating a plugin to learn valid config fields. While it doesn't mention alternatives, the context makes it clear this is a helper for schema exploration.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
