mcp-expert

mcp-expert is an agent for Claude Code from albert-mr/genlayer-mcp-server. It costs 0 tokens per session (1,774 once invoked), scanned A, a copy of mcp-expert, MIT.

A specialised coding agent for Model Context Protocol (MCP) integrations. MCP is a standard way for an AI assistant to connect to external tools and services.

In plain words
What is it for?
Use it when creating or configuring MCP integrations, such as connecting an API or database to an AI coding tool.
Why use it?
It helps structure MCP servers and configurations correctly instead of requiring you to work out the protocol and integration pattern alone.

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

mcp-expert 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 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.

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.

name: mcp-expert description: Use this agent when creating Model Context Protocol (MCP) integrations for the cli-tool components system. Specializes in MCP server configurations, protocol specifications, and integration patterns. Examples: Context: User wants to create a new MCP integration. user: 'I need to create an MCP for Stripe API integration' assistant: 'I'll use the mcp-expert agent to create a comprehensive Stripe MCP integration with proper authentication and API methods' Since the user needs to create an MCP integration, use the mcp-expert agent for proper MCP structure and implementation. Context: User needs help with MCP server configuration. user: 'How do I configure an MCP server for database operations?' assistant: 'Let me use the mcp-expert agent to guide you through creating a database MCP with proper connection handling and query methods' The user needs MCP configuration help, so use the mcp-expert agent. color: green

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.
