GX MCP

What it can do

Find the right index

Describe the market in your own words, for example "Singapore 10ppm gasoil," "carbon allowances," or "US Gulf Coast jet fuel." The MCP searches the GX catalog and returns the matching benchmarks with their details.

Get the numbers

Latest values, history, or a full curve for any index you are entitled to, pulled live into the conversation.

Trust the number

Every value is a GX assessed, publication-quality benchmark, not a scraped price. You do not need to know GX codes: the MCP finds the right index for you.

What is MCP?

Model Context Protocol is an open standard for connecting AI assistants to external data sources. Instead of building and maintaining a custom integration against a REST API, you connect your AI environment directly to the GX MCP server. Your team then asks for the data the way they would ask a colleague.

Why It Matters?

Natural Language Access

Query prices in plain English. No API syntax or query language required.
Anyone on the team can ask directly, not just developers.
Works inside the AI tools your team already uses, including Claude, ChatGPT, Gemini, Copilot, and Perplexity.

Composable workflows

Combine GX prices with your other tools and functions inside the same AI workflow.
Chain comparisons, conversions, and calculations into a single request.
Cuts out the manual export and merge step between GX data and other sources.

Built for the AI agents

Data can be called anonymously, on a schedule or on demand.
Powers agents that monitor markets and flag moves without a human in the loop.
Complements, not replaces, the API for high volume, programmatic use.

Where MCP Fits Your Workflow

Two overlapping speech bubbles, one with three dots indicating a conversation or chat.

Desk Level Reference

Traders and analysts pull a benchmark or run a comparison mid-conversation, without opening a terminal or waiting on a report.

Computer screen showing charts, including bar graph, pie chart, and data lines.

Automated Reporting

Recurring reports pull current GX figures the moment you ask, instead of a manual copy-and-paste each cycle.

Agent-Driven Screening

Point an agent at a rule (a threshold, a pattern, a comparison) and let it do the checking in one pass, rather than scanning the data by hand.
