## What open-market-data does, in the publisher's words

open-market-data is a read-only data layer for stocks, company fundamentals, SEC filings, crypto, and macroeconomic data. The Agent Skill, MCP server, TypeScript client, and CLI all return the same normalized results.

You can use stock data, SEC filings, World Bank indicators, and CoinGecko without an API key. Optional free keys add FRED data, a dedicated CoinGecko quota, and more fallback providers.

- One package, several interfaces: use it as an Agent Plugin, MCP server, TypeScript library, CLI, or experimental WebMCP adapter
- Read-only tools: each tool has a narrow JSON Schema, bounded output, and no trading or arbitrary execution capability
- Useful without keys: stock, SEC, World Bank, and CoinGecko data work out of the box; Binance is also keyless where available

## Skills

- open-market-data: Query read-only stock, company financial, SEC filing, crypto, and macroeconomic data with provenance. Use when an agent needs current market data, public economic data, source comparison, provider diagnostics, or a compact company research snapshot.

Descriptions come from the frontmatter of each SKILL.md, punctuation lightly normalized.

## MCP servers

- open-market-data: transport: stdio; command: node ${PLUGIN_ROOT}/dist/mcp-cli.js
