## What postgres-readonly does, in the publisher's words

This package is an MCP client for a separately deployed read-only database MCP server. The first release talks only to PostgreSQL. The server is Google MCP Toolbox for Databases. The transport is Streamable HTTP, and the endpoint shape is http://host:5000/mcp.

The package contains only plugin.json, mcp.json, a Skill, and docs. It does not contain a Toolbox binary, a database driver, an npm entry, a server module, a connection string, or an access key.

## Skills

- postgres-readonly: Inspect schemas and table structure, and run a single SELECT, WITH, or EXPLAIN, through an internal network read-only PostgreSQL MCP server.

Descriptions come from the frontmatter of each SKILL.md, punctuation lightly normalized.
