What it does

MCP Management is an agent skill from secondsky/claude-skills. Manage MCP servers - discover, analyze, execute tools/prompts/resources. Use for MCP integrations, capability discovery, tool filtering, programmatic execution, or encountering context bloat, server configuration, tool execution errors.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol. The repository describes itself as: Production-ready skills for Claude Code CLI - Cloudflare, React, Tailwind v4, and AI integrations. The licence is MIT.

When your agent uses it

  • MCP integrations
  • Capability discovery
  • Programmatic execution
  • Encountering context bloat

Example prompts

  • “/mcp-management”

Requirements

  • Node.js

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Configuration Management
  2. Capability Discovery
  3. Intelligent Tool Analysis
  4. Tool Execution

What it can do on your machine

Read from SKILL.md and the folder at commit 8837836. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • bunx
    • gemini
    • bun
    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use bunx and npm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

MCP Management loads about 1.5k tokens when it runs. Until then it costs about 63 tokens; SKILL.md has 541 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~63
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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:

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

Core Capabilities

1. Configuration Management

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

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

bash
mkdir -p .gemini && ln -sf .claude/.mcp.json .gemini/settings.json
2. Capability Discovery
bash
# Preferred: Using bun (faster)
bunx tsx scripts/cli.ts list-tools  # Saves to assets/tools.json
bunx tsx scripts/cli.ts list-prompts
bunx tsx scripts/cli.ts list-resources

# Alternative: Using bunx
bunx tsx scripts/cli.ts list-tools
bunx tsx scripts/cli.ts list-prompts
bunx tsx scripts/cli.ts list-resources

Aggregates capabilities from multiple servers with server identification.

3. Intelligent Tool Analysis

LLM analyzes assets/tools.json directly - better than keyword matching algorithms.

4. Tool Execution

Primary: Gemini CLI (if available)

bash
gemini -y -m gemini-2.5-flash -p "Take a screenshot of https://example.com"

Secondary: Direct Scripts

bash
# Preferred: Using bun
bunx tsx scripts/cli.ts call-tool memory create_entities '{"entities":[...]}'

# Alternative: Using bunx
bunx tsx scripts/cli.ts call-tool memory create_entities '{"entities":[...]}'

Fallback: mcp-manager Subagent

Implementation Patterns

Pattern 1: Gemini CLI Auto-Execution (Primary)

Use Gemini CLI for automatic tool discovery and execution.

Quick Example:

bash
gemini -y -m gemini-2.5-flash -p "Take a screenshot of https://example.com"

Benefits: Automatic tool discovery, natural language execution, faster than subagent orchestration.

Pattern 2: Subagent-Based Execution (Fallback)

Use mcp-manager agent when Gemini CLI unavailable. Subagent discovers tools, selects relevant ones, executes tasks, reports back.

Benefit: Main context stays clean, only relevant tool definitions loaded when needed.

Pattern 3: LLM-Driven Tool Selection

LLM reads assets/tools.json, intelligently selects relevant tools using context understanding, synonyms, and intent recognition.

Pattern 4: Multi-Server Orchestration

Coordinate tools across multiple servers. Each tool knows its source server for proper routing.

Quick Start

Method 1: Gemini CLI (recommended)

bash
bun install -g gemini-cli  # or: bun add -g gemini-cli
mkdir -p .gemini && ln -sf .claude/.mcp.json .gemini/settings.json
gemini -y -m gemini-2.5-flash -p "Take a screenshot of https://example.com"

Method 2: Scripts

bash
cd .claude/skills/mcp-management/scripts
bun install  # or: bun install
bunx tsx cli.ts list-tools  # Saves to assets/tools.json
bunx tsx cli.ts call-tool memory create_entities '{"entities":[...]}'

Method 3: mcp-manager Subagent

Dispatch subagent to handle MCP operations, keeping main context clean.

Secure Installation

When installing MCP server packages, follow supply chain security best practices:

  • Block post-install scripts — npm config set ignore-scripts true (or Bun: disabled by default)
  • Cooldown period — Wait 7 days for new package versions to be vetted by the community
  • Audit before installing — Run socket package score npm <pkg> or use socket npm install <pkg> to check packages

Load the dependency-upgrade skill for full security configuration including Socket CLI integration, cooldown setup, lockfile validation, and CI enforcement.

Integration Strategy

Execution Priority

  1. Gemini CLI (Primary): Fast, automatic, intelligent tool selection

    • Check: command -v gemini
    • Execute: gemini -y -m gemini-2.5-flash -p "<task>"
    • Best for: All tasks when available

  2. Direct CLI Scripts (Secondary): Manual tool specification

    • Use when: Need specific tool/server control
    • Execute: bunx tsx scripts/cli.ts call-tool <server> <tool> <args>

  3. mcp-manager Subagent (Fallback): Context-efficient delegation

    • Use when: Gemini unavailable or failed
    • Keeps main context clean
Integration with Agents

The mcp-manager agent uses this skill to:

  • Check Gemini CLI availability first
  • Execute via gemini command if available
  • Fallback to direct script execution
  • Discover MCP capabilities without loading into main context
  • Report results back to main agent

This keeps main agent context clean and enables efficient MCP integration.
