Jourier builds a Model Context Protocol (MCP) server that exposes your Affinity data to ChatGPT. ChatGPT sees structured tool calls (search, read, query, write) and returns deterministic responses. No CSV exports, no copy-paste, no API hallucination. Your team can ask ChatGPT questions about your Affinity data, draft replies that reference it, and run lead and account research with full Affinity context.

The MCP server reads from the same Data Hub that feeds your dashboards and bespoke applications. One modeled layer, many consumers. ChatGPT sees the same numbers your team sees in BI, with the same definitions and the same governance.

Custom fields, picklists, and record types in Affinity accumulate organically. Jourier's modeling captures the meaningful subset (the fields finance and revops actually use), keeps the rest auditable, and ships a layer your analysts can query without learning Affinity's object model first.

Tool calling in ChatGPT works best when the underlying data layer is shaped for the kinds of questions a chat interface invites. Jourier models Affinity for both the operational queries (lookup-by-key, recent-records-by-customer) and the aggregate queries (top-N, cohort summaries) — so ChatGPT's responses cite specific Affinity records when that's what the user wanted, and aggregates when that's what the question demanded.

Result: ChatGPT can answer questions about Affinity data with the same accuracy your dashboards have, because both surfaces read from one modeled layer rather than from separate connectors.

MCP (Model Context Protocol) is the standard ChatGPT uses to talk to external data. Instead of teaching ChatGPT every Affinity API directly, Jourier builds one MCP server that wraps the Data Hub. ChatGPT reads from a clean modeled layer, the same one your BI dashboards and bespoke applications read from. Permissions, governance, and audit logs live in the layer (not in ChatGPT), so what ChatGPT can see and do is bounded by your team, not by OpenAI's defaults.

Can I expose Affinity data to ChatGPT via MCP?

Yes. Jourier builds a Model Context Protocol (MCP) server that wraps your Affinity integration in the Data Hub. ChatGPT sees structured tool calls (search, read, query, optionally write) and returns deterministic responses against the same modeled tables that feed your applications and reports. You can ask ChatGPT questions about Affinity data, run lead and account research, draft replies that reference live records, or have it generate the same dashboards rendered inline in chat. The MCP server runs in your environment or on Jourier's infrastructure, so ChatGPT pulls only the data your team has authorized.

Is Affinity data sent to OpenAI's servers?

Only the slices ChatGPT explicitly queries when a user invokes a tool. The MCP server itself runs on your infrastructure or Jourier's, not on OpenAI's. Through Data Hub permissions you control which Affinity fields, rows, and records ChatGPT can access. Sensitive columns can be masked or excluded entirely; queries can be scoped per user, per role, or per workspace. Audit logs of every tool call live in the layer, so you can review exactly what ChatGPT touched.

Can ChatGPT write back to Affinity via the MCP server?

Yes, scoped to the actions you authorize. The MCP server can expose write tools (create record, update field, post comment, send message) that ChatGPT invokes after a confirmation step. Jourier scopes these tools tightly with allow-lists per role so ChatGPT can't act outside the intended workflow. Two-way patterns we see often: ChatGPT drafts an outbound message, a human approves, ChatGPT posts it back to Affinity. Or ChatGPT updates a status field after a multi-step research workflow finishes.

How fresh is the Affinity data ChatGPT sees?

Where Affinity supports change-data-capture, the data ChatGPT reads is current within seconds. Otherwise scheduled polling and webhooks keep the layer current at the cadence your team sets — typically 5 to 60 minutes for operational data, hourly to daily for slower-moving sources. The MCP server reads from the Data Hub, so ChatGPT sees the same data your dashboards and applications see. No stale snapshots, no second source of truth.

How long does the Affinity → ChatGPT MCP setup take?

First sync is usually instant to one day. A scoped MCP engagement covering Affinity plus the workflows it powers (pipeline analytics, conversion-funnel reporting) runs typically two to six weeks before going to production. Bigger transformations are split into phases, each shipping value before the next begins. Jourier handles the Affinity integration, the Data Hub modeling, the MCP tool definitions, the access controls, and the runbooks. Your team validates the workflows.

Can multiple team members use the ChatGPT integration with Affinity?

Yes. The MCP server is designed for team use. Each user authenticates against your identity provider (Okta, Microsoft, Google) and the server scopes their queries by role, region, or department. Two team members hitting the same MCP tool will both get answers consistent with the underlying data layer — and consistent with each other. Concurrency, rate limits, and per-user quotas are handled in the server.

Who owns the Affinity → ChatGPT MCP server code?

You do. Jourier delivers the MCP server, the Data Hub it wraps, the data model, the access-control config, and the documentation as part of the engagement. Self-host or have us host. Hand it to another vendor whenever you want, or take it over with your own team. No per-seat licences from Jourier, no platform fees if you self-host. The ChatGPT subscription stays directly with OpenAI.

What does a Affinity → ChatGPT engagement cost?

Bespoke project, scoped to the Affinity data and the workflows that matter. Pricing is project-based, not subscription-based: a fixed-fee build, then optional managed-services if you want Jourier to run the server. No per-seat licences from us, no platform fees if you self-host. ChatGPT usage (your seats, your tokens) stays directly billed by OpenAI. We size every engagement to the data layer's actual scope, not to a one-size-fits-all price card.
