A useful AI research session starts with a question and ends with evidence that another reader can follow. For an FX analyst, that might be a policy-rate comparison, a short list of upcoming releases, or an explanation of how recent inflation observations fit the central-bank discussion. The assistant needs data tools for that work, rather than relying on its memory of changing economic figures.
FXMacroData's hosted Model Context Protocol server gives compatible AI hosts a tool-connected route to macro observations and research context. The host manages the conversation and tool permissions; FXMacroData supplies the requested data. This guide follows one bounded USD research brief through connection, retrieval and interpretation.
Who this is for: Analysts using a compatible AI assistant or coding environment who want research grounded in returned observations.
1. Add the hosted server in your AI host
Use a host that supports a remote HTTP MCP connection and permits custom servers for your account or workspace. Add https://mcp.fxmacrodata.com using the host's connection flow, then review and enable the discovered tools. The MCP setup guide explains the client-specific choices.
Where authentication is offered, use the supported OAuth flow or protected header settings. Public USD access can provide an initial evaluation path; protected datasets require the appropriate access. Keep credentials in the host's connection settings, rather than appending them to the server URL or putting them in the conversation.
- Connect the AI host
- Discover the available data tools
- Ask a bounded research question
- Inspect observations and sources
- Write a brief with stated uncertainty
2. Define the brief before asking for an answer
Start with a currency, horizon and output format. For example, a morning USD note can ask for the latest US inflation observation and confirmed USD events over a short planning window. That is a narrower and more checkable task than asking the assistant to explain everything happening in foreign exchange.
Use FXMacroData to prepare a USD macro brief.
Retrieve the latest available US inflation observation.
State the series, reference period, value and unit.
Keep the returned source link with the observation.
List confirmed USD events scheduled this week in UTC.
Separate the observations from your economic interpretation.
Identify unavailable fields and any access delay.The prompt defines a research task, not an example market result. Read the tool output before accepting the finished prose. Check whether the response actually supplies the requested unit, source and time basis. If a field is unavailable, the assistant should preserve that uncertainty instead of producing a plausible replacement.
3. Build an argument from the evidence
A macro brief should connect a measured observation to a specific question. A change in inflation can matter to the policy discussion, but it is not automatically a forecast surprise or a currency signal. The assistant should distinguish the latest value from the previous value, and distinguish both from a verified market expectation when one is actually supplied.
For an EUR/USD note, request the euro-area context as well as the USD context before making a relative-policy argument. For an event-risk note, explain which upcoming releases could challenge the interpretation. This is where an assistant helps organise reasoning: the retrieved figures establish the evidence, while the narrative explains why those particular facts matter.
| Choice | Research consequence |
|---|---|
| MCP-connected assistant | Interactive discovery and source-linked research in a compatible host. |
| Direct REST application | A predetermined series requested by code for a notebook or report. |
| Dashboard | Visual review of a selected series, pair or release schedule. |
4. Move repeatable calculations into a defined workflow
Once the research question is stable, a deterministic application may use REST for a known series. The request below shows the public endpoint and a placeholder header; the placeholder is not a usable credential:
curl "https://api.fxmacrodata.com/v1/announcements/usd/inflation?limit=1" \
-H "X-API-Key: YOUR_API_KEY"Use the application route when exact parameters, stored responses and repeated calculations matter more than conversational discovery. Keep the series and period context when moving results into a notebook. For an AI-facing question, MCP remains the direct route to discover and call the tools available in the selected host.
A current history response does not by itself reconstruct a past information set. A strategy study needs the relevant vintage and availability evidence for each decision. Preserve those distinctions when an assistant proposes a backtest, and use the point-in-time research guide to define the required inputs.
5. Review the brief as a research product
Check that every numerical claim can be traced to a returned observation or a cited source. A calendar entry describes a scheduled event; it should not be rewritten as an observed publisher time. A valid empty result should remain unavailable evidence. These distinctions keep a fluent answer from becoming more certain than its inputs.
Measure the finished workflow by the quality of the brief: whether its sources open, whether its reference periods and units are explicit, and whether another analyst can distinguish evidence from interpretation. The useful outcome is a shorter path to a reviewable macro argument, with the model doing the organising and the connected tools supplying the data.
For a ready-made starting point in ChatGPT, use the Custom GPT guide. For another compatible host, follow its specific connection instructions and begin with the same bounded research question.
