What is mcp CLAUDE.md?

Project instructions for an MCP server, a program that lets AI tools call Supadata services for web scraping and video transcripts.

Use it when building, testing, linting, formatting, or starting this TypeScript server.

It gives coding agents the project context, standard commands, and ways to run focused tests without searching through the repository.

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	$0.01707	$0.01707
Opus 5.5	$0.00683	$0.00683
Sonnet 5.5	$0.00341	$0.00341
Haiku 4.5	$0.00171	$0.00171

Security

Grade A, and why

mcp 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 9d 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.

Project Overview

This is a Model Context Protocol (MCP) server implementation for Supadata web scraping and video transcript integration. The project provides nine main tools: supadata_transcript, supadata_check_transcript_status, supadata_scrape, supadata_map, supadata_crawl, supadata_check_crawl_status, supadata_metadata, supadata_extract, and supadata_check_extract_status for video transcription, web scraping, URL discovery, batch crawling, media metadata retrieval, and AI-powered structured data extraction.

Key Commands

Development Commands

npm run build - Compile TypeScript to JavaScript and make executable
npm run test - Run Jest tests with ESM support
npm run lint - Run ESLint on TypeScript files
npm run lint:fix - Run ESLint with auto-fix
npm run format - Format code with Prettier
npm run start - Start the compiled server

Single Test Execution

npm run test -- --testNamePattern="should handle scrape request" - Run specific test
npm run test -- src/index.test.ts - Run specific test file

Architecture

MCP Server Structure

The server is built using the @modelcontextprotocol/sdk and runs on stdio transport. The main server logic is in src/index.ts with the following key components:

Server Creation: createServer() function creates an McpServer instance
Tool Registration: Nine tools are registered with input validation using Zod schemas
Error Handling: Comprehensive error handling with retry logic and exponential backoff
Configuration: Environment-based configuration with defaults

API Integration

The server integrates with Supadata's JavaScript SDK (@supadata/js) and provides:

Video Transcription: Extract transcripts from YouTube, TikTok, Instagram, Twitter, and file URLs
Web Scraping: Single page content extraction to Markdown
URL Mapping: Website URL discovery and indexing
Crawling: Asynchronous batch crawling of multiple pages
Media Metadata: Retrieve metadata from YouTube, TikTok, Instagram, Twitter/X, and Facebook URLs
Structured Extraction: AI-powered extraction of structured data from video content
Status Checking: Monitor crawl, transcript, and extract job progress and retrieve results

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.
