# JSON Schemas

Agent Plugins publishes separate JSON Schemas for the plugin manifest and MCP server configuration. Clients use each canonical `$schema` identifier to select locally supported validation and interpretation rules; they do not retrieve schemas while loading a plugin.

- [Plugin manifest schema](https://agent-plugins.org/schemas/1.0.0/plugin.schema.json) — Validate the root plugin.json manifest.
- [MCP configuration schema](https://agent-plugins.org/schemas/1.0.0/mcp.schema.json) — Validate the root mcp.json document and individual server entries.

The [specification](/spec) is authoritative if its requirements conflict with a machine-readable schema.
