Agent Plugins Validator v1.0.0 tool

[rbadillap]

Hello everyone,

I built a validator for the Agent Plugins 1.0.0 spec.

Validator

• Paste plugin.json or mcp.json
• Drop a file
• Load from GitHub
• Auto-detect the manifest type
• Validate against the Agent Plugins 1.0.0 schemas
• Run validation locally in the browser

For agents

MCP

A Streamable HTTP MCP endpoint exposes a validate tool, so agents can validate plugins programmatically.

API

The project also exposes an OpenAPI 3.1 API with a versioned /api/v1 interface for programmatic access.

Try it here:

https://agent-plugins.directory/tools/validate

Feedback is welcome, especially validation cases or edge cases that should be covered.
