mcp-postgres: Command for Claude Code

.claude/commands/mcp-docs.md

mcp-docs is a command for Claude Code from fabriciofs/mcp-postgres. It costs 0 tokens per session (718 once invoked), scanned A, original, MIT.

A writing guide for documenting MCP servers. MCP, or Model Context Protocol, is a way for AI agents to connect to external tools and data.

In plain words
What is it for?
Use it to create an MCP server README with setup steps, environment variables, configuration examples, tool descriptions, parameters, responses, and development commands.
Why use it?
It gives documentation a consistent structure so developers can understand installation, configuration, available tools, inputs, and outputs.

Command for Claude Code

Written for Claude Code: $ARGUMENTS substitution.

This is fabriciofs/mcp-postgres's own configuration. It tells Claude Code how to work on mcp-postgres itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-postgres configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mcp-docs scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
