What is mcp-server CLAUDE.md?

Repository instructions for a collection of MCP servers, which connect AI agents to outside services through a standard format. They cover a Notion server for reading and creating pages and a Playwright server for controlling browsers and scraping websites.

Working on the Notion and Playwright MCP servers, including page operations, browser automation, web scraping, and the supported browsers.

They explain how the repository is organized and what has been implemented, tested, and connected to Claude Desktop and Claude Code. This gives an agent project-specific guidance before it changes the code.

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	$0.03156	$0.03156
Opus 5.5	$0.01262	$0.01262
Sonnet 5.5	$0.00631	$0.00631

Security

Grade A, and why

mcp-server CLAUDE.md 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 2mo 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.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

This is a collection of MCP (Model Context Protocol) servers that connect Claude Desktop and Claude Code to various external services via standardized protocols. The servers act as bridges, translating Claude's natural language requests into API calls.

Key Architecture Pattern:

Claude Desktop/Code ↔ MCP Protocol (JSON-RPC/STDIO) ↔ MCP Servers ↔ External APIs

Available MCP Servers

Notion MCP Server (notion-mcp/): Notion integration for reading and creating pages
Playwright MCP Server (playwright-mcp/): Browser automation and web scraping

Project Status ✅

Successfully Implemented and Tested:

✅ Multi-server MCP architecture with workspace configuration
✅ Notion MCP Server: Full CRUD operations with rich text and batch processing
✅ Playwright MCP Server: Headful browser automation with visual debugging
✅ Claude Code integration with all 9 MCP tools (2 Notion + 7 Playwright)
✅ Real-time browser interaction with slowMo visualization
✅ Multi-browser support (Chromium, Firefox, WebKit)
✅ Comprehensive documentation with usage guides and troubleshooting

Latest Update: 2025-09-22 - Successfully tested headful mode browser automation with visual confirmation

Claude Code Integration

Claude Code fully supports MCP tools. To add the MCP servers to Claude Code:

Notion MCP Server

# Add Notion MCP server to Claude Code
claude mcp add --transport stdio notion "node" "/path/to/mcp-servers/notion-mcp/server.js" --env NOTION_TOKEN="your_token_here"

# Example with actual project path
claude mcp add --transport stdio notion "node" "/Users/tutleJ/Desktop/Repository/notion-mcp-server/notion-mcp/server.js" --env NOTION_TOKEN="ntn_your_actual_token_here"

Playwright MCP Server

# Add Playwright MCP server to Claude Code
claude mcp add --transport stdio playwright "node" "/path/to/mcp-servers/playwright-mcp/server.js"

# Example with actual project path
claude mcp add --transport stdio playwright "node" "/Users/tutleJ/Desktop/Repository/notion-mcp-server/playwright-mcp/server.js"

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.
