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
# 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)
gemini -y -m gemini-2.5-flash -p "Take a screenshot of https://example.com"
Secondary: Direct Scripts
# 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:
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)
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
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.
