What is ck:mcp-management?

A toolkit for finding, understanding, and using MCP servers and the tools or data they expose. MCP is a standard connection between AI agents and external tools, services, or resources.

Use it to discover MCP tools, prompts, and resources, choose capabilities for a task, run MCP operations, and manage several MCP servers.

It helps select only the relevant capabilities from multiple servers instead of loading every available tool into the working context. It also supports managing server configurations and executing discovered tools.

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.

Model	Per session	Once invoked
Fable 5	$0.00037	$0.01802
Opus 5	$0.00018	$0.00901
Sonnet 5	$0.00007	$0.00360
Haiku 4.5	$0.00004	$0.00180

Security

Grade A, and why

ck:mcp-management 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 3d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/cli.ts, scripts/mcp-client.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

MCP Management

Skill for managing and interacting with Model Context Protocol (MCP) servers.

Overview

MCP is an open protocol enabling AI agents to connect to external tools and data sources. This skill provides scripts and utilities to discover, analyze, and execute MCP capabilities from configured servers without polluting the main context window.

Key Benefits:

Progressive disclosure of MCP capabilities (load only what's needed)
Intelligent tool/prompt/resource selection based on task requirements
Multi-server management from single config file
Context-efficient: subagents handle MCP discovery and execution
Persistent tool catalog: automatically saves discovered tools to JSON for fast reference

When to Use This Skill

Use this skill when:

Discovering MCP Capabilities: Need to list available tools/prompts/resources from configured servers
Task-Based Tool Selection: Analyzing which MCP tools are relevant for a specific task
Executing MCP Tools: Calling MCP tools programmatically with proper parameter handling
MCP Integration: Building or debugging MCP client implementations
Context Management: Avoiding context pollution by delegating MCP operations to subagents

Core Capabilities

1. Configuration Management

MCP servers configured in .codex/.mcp.json.

Gemini CLI Integration (recommended): Create symlink to .gemini/settings.json:

mkdir -p .gemini && ln -sf .codex/.mcp.json .gemini/settings.json

See references/configuration.md and references/gemini-cli-integration.md.

GEMINI.md Response Format: Project root contains GEMINI.md that Gemini CLI auto-loads, enforcing structured JSON responses:

{"server":"name","tool":"name","success":true,"result":<data>,"error":null}

This ensures parseable, consistent output instead of unpredictable natural language. The file defines:

Mandatory JSON-only response format (no markdown, no explanations)
Maximum 500 character responses
Error handling structure
Available MCP servers reference

Changes

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.
