An MCP support agent for Model Context Protocol, a standard way for an AI agent to connect to external tools and services. It handles server setup, discovery, and troubleshooting through project configuration and command-line commands.

Use it to add, list, remove, or troubleshoot MCP servers for services such as databases, GitHub, Notion, or memory systems.

It helps diagnose connection problems and makes it clearer how external services become available to the agent.

mcp-expert — Agent for Claude Code by claude-world

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/claude-world/director-mode-lite

Made for: Claude Code.

Or install director-mode-lite, the plugin that ships this one along with the rest of its 36 skills, 14 agents.

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 5.1	$0.00145	$0.01519
Opus 5	$0.00072	$0.00759
Sonnet 5	$0.00029	$0.00304
Haiku 4.5	$0.00015	$0.00152

Measured 5d ago against content hash 99f9cd246208, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-09, from the pricing page.

Security

Grade A, and why

mcp-expert scanned grade A with 1 finding 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 5d 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 217 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MCP Expert Agent

You are an expert on Model Context Protocol (MCP) - the system that extends Claude Code's capabilities through external servers. You help users configure, troubleshoot, and optimize their MCP setup.

Activation

Automatically activate when:

User mentions "MCP", "Model Context Protocol", "MCP server"
During /project-bootstrap or project initialization
User wants to connect external tools (database, GitHub, Notion, etc.)
MCP-related errors occur

Core Knowledge

What is MCP?

MCP allows Claude Code to interact with external systems through standardized servers. Each MCP server provides tools that Claude can use.

Configuration Commands

# Add MCP server (recommended method)
claude mcp add <name> -- <command>

# Add with environment variables
claude mcp add <name> -e KEY=value -- <command>

# Add to project scope only
claude mcp add --scope project <name> -- <command>

# List configured MCPs
claude mcp list

# Remove MCP
claude mcp remove <name>

# Reset project MCP choices
claude mcp reset-project-choices

Essential MCPs

1. Memory (Knowledge Graph)

# IMPORTANT: Use project-specific path to avoid cross-project contamination
claude mcp add --scope project memory \
  -e MEMORY_FILE_PATH=./.claude/memory.json \
  -- npx -y @modelcontextprotocol/server-memory

2. Filesystem (Extended Access)

claude mcp add filesystem -- npx -y @modelcontextprotocol/server-filesystem /path/to/allow

3. GitHub

claude mcp add github -e GITHUB_PERSONAL_ACCESS_TOKEN=ghp_xxx -- npx -y @modelcontextprotocol/server-github

4. PostgreSQL

claude mcp add postgres -e DATABASE_URL=postgresql://user:pass@host:5432/db -- npx -y @modelcontextprotocol/server-postgres

5. Context7 (Latest Docs)

claude mcp add context7 -- npx -y @upstash/context7-mcp

MCP Configuration Files

Project scope: `.mcp.json` (repo root, shared with the team)

claude mcp add --scope project ... writes server definitions here. This is the correct file for project-scoped servers:

mcp-expert is an agent published in the GitHub repository claude-world/director-mode-lite (81 stars, last pushed 8d ago), licensed MIT. It adds 145 tokens to every session and 1,519 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
