For UK manufacturers running EFACS E/8

An EFACS MCP server that answers from EFACS E/8 within each person's own EFACS permissions

An EFACS MCP server gives Claude, ChatGPT or Copilot named tools for works orders, engineering changes, contracts and field service jobs in EFACS E/8. Exel publishes no API documentation; the interface is clarified with Exel through the customer portal first. Exel ships no MCP server as of 21 September 2026, so Pexon builds one against your installation.

Why EFACS is hard for agents

Where a EFACS connection needs engineering, not configuration

01 · Documentation

No public API documentation at all

Exel publishes no API reference, protocol or authentication description. Scope has to be clarified with Exel or through the customer portal before any estimate, which is why the blueprint starts there.

02 · Network

One server per customer

EFACS runs mostly on-premise or Exel-hosted for a single customer. Network access to your EFACS server has to be arranged for your installation, and that is a firewall decision your IT team owns.

03 · Configuration

Heavily configured per customer

Configurator, contract control and workflows are set up per customer. Mapping questions such as 'which works orders are late on contract C' to records is installation-specific work, done with your EFACS owners.

04 · Ecosystem

Small vendor, no community libraries

Exel is a small independent vendor based in Nottingham since 1985. No community libraries or connectors were found, so there is no existing code to start from; everything is built and tested against your system.

EFACS at a glance: interfaces, access and what exists for AI

What we found
InterfacesEFACS E/8 integration interfaces (not published, docs behind customer or partner login): Exel only says EFACS communicates with other systems via 'industry standard protocols'; technical material sits in the Exel customer and partner portals · Power BI and BIRT dashboards (Version 6) (database (reporting), docs not published): Version 6 ships Power BI and BIRT dashboards; how they access EFACS data is not documented publicly
AuthenticationNot documented publicly.
Vendor MCP serverNo vendor server. No EFACS MCP server, agent API or LLM assistant on exel.co.uk.
Vendor AI assistantExel markets EFACS as AI-enabled for purchase invoice capture, using Google Document AI Invoice Parser with OCR, and for workflow automation; there is no assistant.
Other connectorsNone found.

What we build

A first EFACS tool list, written as the manifest your IT team signs

Exel Computer Systems plc does not publish its interface reference, so every backend below is confirmed against your installation in the blueprint before a tool is built.

# efacs-mcp-server: tool manifest, draft for blueprint week 1
# Every tool runs as the person asking. Nothing is written without a person confirming.
tools:
  get_works_orders:        # status, due date, contract -> works orders with progress
    backend: confirmed in blueprint
    mode: read
  get_part_changes:        # part number -> open change control records
    backend: confirmed in blueprint
    mode: read
  get_contract_status:     # contract -> cost, progress and open orders
    backend: confirmed in blueprint
    mode: read
  list_field_service_jobs: # customer, date range -> open jobs and engineers
    backend: confirmed in blueprint
    mode: read
  draft_sales_order:       # customer, items -> sales order proposal for a person to confirm
    backend: confirmed in blueprint
    mode: propose
audit: every call logged with user, tool, arguments and the EFACS response

The manifest is the contract. A question that needs an operation not on it gets a new line and a review, not a wider permission.

EFACS holds the records. An assistant without a governed way in answers from whatever someone pasted into the chat. The connector is the governed way in: named operations, the person's own permissions, every call logged.

What the connector answers, and what it will not do

Questions it answers

  • Which works orders for contract C are behind the planned completion date?
  • What engineering changes are pending for part P?
  • Which field service jobs for customer X are open this week?

What it will not do

  • Read more than the asking user may read in EFACS; how each person's EFACS rights carry through the interface is tested in the blueprint before any tool goes live.
  • Create a sales order by itself: the only write tool drafts one, and a person confirms it in EFACS.
  • Write to the EFACS database directly: every change goes through an interface Exel supports and a person.

When this is the wrong page

If the need is dashboards and KPIs, the Power BI and BIRT dashboards in EFACS Version 6 are the shorter path, and cross-year analysis belongs in a data warehouse. A connector is right when people ask questions in Claude, ChatGPT or Copilot, or need EFACS combined with another system.

Start with the Readiness Blueprint.

Two weeks, €4,900 fixed price. Week one agrees the tool list with your EFACS owners and checks every backend against your release and licence. Week two tests whether a person's own EFACS permissions reach through the connector. You keep the manifest and a costed build plan, whoever builds it. All prices are net and exclude VAT.

What we need from you: a named EFACS administrator, a test or sandbox system we may call, and one business owner who can say which questions the assistant should answer first. The first production connector is usually a use-case pilot from €15,000; it runs in your environment, and the code is yours.

Questions EFACS teams ask before the first tool call

Does EFACS have its own MCP server?

Not as of 21 September 2026. Exel markets EFACS as AI-enabled for purchase invoice capture and workflow automation, but offers no MCP server, agent API or assistant. An MCP server for Claude, ChatGPT or Copilot has to be built on the interfaces Exel supports for your installation.

Do we need extra EFACS licences or access for an AI connector?

Exel does not publish its integration interfaces, their authentication or their licensing. We need that material through you, from the Exel customer portal or from Exel directly, and the licence question is one to check with Exel. The blueprint answers both before any build starts.

Can the assistant see data a user is not allowed to see in EFACS?

No. How each person's EFACS rights carry through the interface is tested in the blueprint, and no tool goes live until two users asking the same question get the answers their own rights allow. Writes only happen as drafts a person confirms in EFACS.

What does an EFACS connector cost?

The two-week Readiness Blueprint is fixed at €4,900: agreed tool list, backends checked against your release, identity tested end to end, costed build plan. The production connector is usually a use-case pilot from €15,000. Prices are net, excluding VAT.

Next step

Not a sales call. An architecture call.

Thirty minutes with the engineer who would build the connector, with your EFACS administrator in the room if you like.
