TickerLayer

Market data inside Claude. Ask how Bitcoin, gold or the US 10-year yield moved today, pull a month of daily bars, or check whether Tokyo is open, and Claude answers with data from one consistent API across crypto, forex, stocks, indices, ETFs, commodities, perpetual futures and government bond yields.

The plugin connects Claude to the hosted TickerLayer MCP server and adds a skill that teaches Claude to use it well: which tool fits a question, how symbols are written, and why a quiet market is usually closed rather than broken.

Ask in plain language:

• "How are Bitcoin and gold doing today?"
• "Pull daily EURUSD bars for June and summarize the trend."
• "Is the US stock market open right now? When does Tokyo open next?"
• "What is the US 10-year Treasury yield, and how does Germany compare?"
• "Open the TickerLayer markets board."

What you get

Coverage: crypto, forex, US and international stocks, indices, ETFs, commodities, perpetual futures and government bond yields, all through one consistent schema.

Tools. Every tool only reads data.

Tool	What it does
get_snapshot	Last price, bid and ask, previous close and change in one call
get_quote	Latest bid and ask
get_last_trade	Most recent trade: price, size and time
get_previous_close	Previous daily bar, or the latest settled intraday bar
get_history	OHLCV bars from 1 minute to 1 day between two dates
list_symbols	The symbols available for an asset class, with search
get_market_status	Whether a market is open, closed, or in pre-market or post-market
get_market_sessions	Trading session times for a market on a given date
get_market_holidays	Market holidays and early closes
get_bond_yield	Latest government bond yield, such as US:10Y
open_markets_board	An interactive board of ten widely followed markets, with charts and search
search_symbols	Powers the search box inside the markets board

Skill: market-data covers tool selection, symbol conventions (stocks always use COUNTRY:TICKER, for example US:KO), market hours and holidays, error handling, and a parameter reference.

Install

Claude on the web, desktop and mobile, and Cowork:

1. Add TickerLayer from the directory in Customize > Plugins.
2. Open the plugin's Connectors tab, add or connect TickerLayer, and sign in with your TickerLayer account. On Team and Enterprise plans, an Owner adds the connector for the organization first.

The skill loads either way, but the tools work only once the connector shows Connected.

Claude Code:

/plugin marketplace add tickerlayer/agent-plugin
/plugin install tickerlayer@tickerlayer

Then run /mcp, select plugin:tickerlayer:tickerlayer and choose Authenticate.

Other agent clients: this repository is also an Agent Plugins 1.0.0 package for Codex CLI, Cursor and VS Code. Install steps for each client are at https://tickerlayer.com/ai/agent-plugins.

Account and sign-in

You need a TickerLayer account, and a free plan is available. Create one at https://tickerlayer.com/signup and compare plans at https://tickerlayer.com/pricing.

Sign-in uses OAuth. The TickerLayer sign-in page opens, you approve the connection, and no key is pasted into Claude or stored in this package. Clients that you configure by hand can send an API key in the x-api-key header instead. Keep keys in your client's private settings and never commit them.

Data requests count against your plan's monthly quota. Opening the markets board costs ten requests, and each chart, search or refresh inside it costs more.

What this plugin runs and sends

The plugin contains no executable code: a manifest, a reference to the hosted MCP server, a skill written in Markdown, and an icon. Nothing runs on your machine.

Claude connects only to TickerLayer: https://mcp.tickerlayer.com/mcp for tool calls and api.tickerlayer.com for sign-in tokens. A tool call carries your sign-in token and the tool's parameters, such as the asset class, symbol, dates or market code. The server reads TickerLayer's own API and returns the result. The markets board is drawn inside Claude and loads nothing from other sites.

You sign in through your browser on tickerlayer.com, which uses our sign-in service and also offers Google or GitHub sign-in. The website loads analytics and support chat only with your cookie consent. The privacy policy covers all of this.
