## What base64-codec does, in the publisher's words

A GitHub Copilot Agent Plugins 1.0 marketplace with one plugin: Base64 Codec.

Encodes text to Base64 or decodes Base64 back to text. The agent calls a bundled, zero-dependency MCP tool, so its work shows up as a concrete result in Copilot chat.

- Agent: Base64 Codec (appears in the Copilot agent picker)
- MCP tool: base64: returns the encoded or decoded string
- Set chat.plugins.enabled to true in VS Code settings.
- Add this marketplace to chat.plugins.marketplaces: json { "chat.plugins.marketplaces": ["ankmay0/base64-codec"] }
- Open the Extensions view, search @agentPlugins, and install base64-codec.
- Select Base64 Codec in the Copilot agent picker and try: > Encode "hello" to base64

The plugin's MCP server is trusted automatically (no startup prompt).

From the project README, punctuation lightly normalized. Full text: https://raw.githubusercontent.com/ankmay0/base64-codec/HEAD/README.md
