03-mcp-configuration

03-mcp-configuration is a cursor rule for Cursor from Bilal140202/the-lord-of-the-skills. It costs 31 tokens per session (359 once invoked), scanned A, a copy of 03-mcp-configuration, MIT.

A set of instructions describing which Model Context Protocol servers are available and what they can do. MCP is a standard way for an AI agent to connect to external tools and data sources.

In plain words
What is it for?
Use it to document MCP servers from a mcp.json file, including their purpose, commands, paths, authentication, limits, and error handling.
Why use it?
It gives the agent the configuration and usage details needed to choose the right connected server and follow its access rules.

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

03-mcp-configuration 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 12d 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.

What it actually says

MCP Server Configuration

This file documents the Model Context Protocol (MCP) servers available in your environment. It helps the AI understand which tools it can use for tasks involving memory, filesystem operations, web interaction, etc.

How to Provide Your MCP Configuration

  1. Open Cursor Settings (Cmd+, or Ctrl+,)
  2. Go to the 'MCP' section
  3. Click 'Add new global MCP server' (opens mcp.json)
  4. With mcp.json open, return to chat and provide context using @

Available MCP Servers

Example Server Format

### MCP Server Name
Purpose: Provides file system access for reading/writing files
When to Use: For file operations (read, write, check existence)
Key Commands: `read_file`, `write_file`, `file_exists`, `list_directory`
Usage Instructions: Always use absolute file paths

Server Template

### MCP Server
Purpose: 
When to Use: 
Key Commands: 
Usage Instructions: 
Access Scope: 
Authentication: 
Rate Limits: 
Error Handling: 

Important Notes

  • Always use absolute paths for filesystem operations
  • Tool descriptions are derived from available tool descriptions in your configuration

NOTE TO AI:

  • Populate this file based on user's .cursor/mcp.json
  • For each server, list name and brief description of purpose/commands
  • Include relevant configuration details (paths, environment variables, etc.)
  • Remove example section when populating with actual MCP servers

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
