Ibkr HttpapiREST and MCP Access to Interactive Brokers

What Is a REST and MCP Bridge for Interactive Brokers?

A bridge sits between your code and a broker's connection layer. Connecting directly to Interactive Brokers typically means handling persistent sessions, contract identifiers and asynchronous messages, which is a lot of plumbing before you write any trading logic. A REST bridge turns those steps into ordinary HTTP requests that any language can make.

MCP, the Model Context Protocol, adds a second way in. It lets AI assistants and agent frameworks discover and call the same functions as tools. A research agent could ask for a snapshot, pull bars and then report back, without you writing a custom client.

The practical benefit is separation. Your strategy code can stay simple and focus on decisions, while the service handles the broker-specific work. If you later change how you run your strategy, the interface your code sees stays the same.

Who Is Ibkr Httpapi For?

The project suits people who already write code and want an Interactive Brokers account to behave like an API. A typical user might be a developer building a personal dashboard that refreshes quotes every few seconds, or a quantitative hobbyist who wants historical bars to test a simple moving average rule in Python.

It also fits teams experimenting with AI agents. Because the service exposes MCP tools, an agent can read market data within limits you define, which is useful for research prototypes. Keep these experiments on a paper or test setup until you understand how the agent behaves.

It is a poor match for people who want a point-and-click interface. There is no chart window or tax report generator in the project. If your goal is to review your holdings visually, a tracker built for that purpose will serve you better, and you can still use this service as a data source for custom views.

How Market Classes Shape Your Requests

Every market type has its own URL prefix, which the project calls the class segment. Requests follow the same shape: a class, a symbol and an action such as contract details, snapshot, bars or ticks. Once you learn the pattern for one asset class, you can apply it to the others with only small changes.

Consider a watchlist script that checks ten instruments every minute. If the stocks, futures and forex pairs all use the same route structure, you can write one loop and pass in different classes and symbols. That reduces bugs and makes the code easier to review.

Options are a special case because snapshot responses include Greeks. A script monitoring a single option contract can read price and sensitivity values in one call, which saves you from calculating them separately. Crypto and CFD prefixes follow the same logic, so the layout does not change when you add a new market to your watchlist.

Key Terms: Bars, Ticks, Greeks and Enrichment

Understanding the vocabulary makes the data easier to use. An OHLC bar records the open, high, low and close for a time interval. The high and low show how far price travelled, and the open and close show where it started and ended. Comparing these values across bars is the basis of most chart-based analysis.

A tick is a single recorded event, such as a trade or a quote update. The bid is the highest price a buyer currently offers, and the ask is the lowest price a seller accepts. The gap between them is the spread, which matters when you estimate the cost of entering or exiting a position.

Greeks are sensitivity measures for options, including delta, gamma, theta and vega. Delta approximates how much an option price moves when the underlying moves by one unit. Technical enrichment adds indicator values to bars, so your code receives derived measures alongside raw prices. Always check the exact definitions in the project documentation before building logic on them.

Supported coins

The project covers stocks, options, futures, forex, crypto and CFDs as market types. Its documentation mentions Bitcoin (BTC) as an example of a crypto asset you can request, so crypto symbols follow the same URL pattern as other classes.
