TickerLayer Agent Plugin

An Agent Plugins 1.0.0 package that gives AI agents market data: it bundles the hosted TickerLayer MCP server with a market-data skill that teaches agents how to use it well.

• MCP server: https://mcp.tickerlayer.com/mcp (Streamable HTTP) with tools for quotes, last trades, snapshots, previous/settled closes, OHLCV history, symbol discovery, market status/sessions/holidays, and government bond yields.
• Coverage: crypto, forex, stocks, indices, ETFs, commodities, and bonds.
• Skill: skills/market-data/ — tool selection guidance, symbol conventions (stocks are always COUNTRY:TICKER, e.g. US:AAPL), discovery-first workflow, market-calendar awareness, and error handling.

ChatGPT

ChatGPT connects to the MCP server directly — no plugin package needed. In ChatGPT on the web: Settings → Apps & Connectors → Advanced settings → Developer mode, then Create a connector with the server URL https://mcp.tickerlayer.com/mcp and Authentication: OAuth. Sign in with your TickerLayer account when prompted, then enable it in a chat from the + menu → Developer mode.

Authentication

• OAuth (default): clients that implement MCP authorization discover the authorization server automatically on first connect — sign in with your TickerLayer account. No keys to paste, nothing stored in this package.
• API key (manual configs): clients configured by hand can send an x-api-key header instead. Get a key at https://tickerlayer.com/dashboard. Keep keys in your client's local, private configuration — never commit them.

This package intentionally ships no credentials and no headers; per the Agent Plugins spec, auth is managed by the client.
