Fergus MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Fergus and the rest of your systems. It gives your agent 91 Fergus actions (46 reads, 38 writes and 7 that wait for a confirmation) and holds the Fergus credential itself, so the agent never does. It paces Fergus's limits and records every call.

Set up

Connect Fergus in three steps.

01
Add actionlake to Claude.
Run the command once in Claude Code; its consent page can create a free sandbox: 100,000 calls a month, no card. In the Claude app, add a custom connector with the URL below and paste your key on the consent page. Creating a new sandbox from the Claude app is not yet tested by us.

Top actions

The Fergus API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 44 of Fergus's 45 action names are shared with at least one other connector, so an agent learns them once.

One ask fetches from Fergus and another system, joins the rows on the same customer on our side, and hands your agent the answer, not every row.

Governance for Fergus

Destructive actions wait for a yes.

7 Fergus actions are destructive. These are all of them:

Deletes a customer by IDfergus.customers.delete
Deletes a calendar eventfergus.calendar_events.delete
Soft-delete a taskfergus.tasks.delete
Voids a quotefergus.quotes.void
Void a job phase by JobId and Job PhaseIdfergus.job_phases.void
Delete a filefergus.attachments.delete
Delete stock on hand on job phasefergus.stock_on_hand.delete

A destructive action runs only with confirm: true. Under the human policy the agent cannot confirm for itself: the run stops until a named person approves, in the console or from a signed link in an email. The cap on a key is refused before the call is sent, never after.

Questions

The Fergus MCP server, answered.

Is there a Fergus MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 91 Fergus actions across quotes, jobs, job phases and tasks, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Fergus.

What do I need to connect Fergus?

Fergus personal access token (in Fergus. The free call account { op: "connections.requirements", service: "fergus" } lists exactly what to paste.

Can an AI agent delete or change things in Fergus?

Only if its key allows it, and only with an explicit confirmation. 7 Fergus actions are destructive, including deletes a customer by ID, deletes a calendar event and soft-delete a task. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it.

Will an AI agent use up my Fergus API limit?

actionlake paces every call to the limits in the Fergus service file: 100 calls a minute per connection. Repeated reads are answered from cache (46 Fergus actions can be), which never reaches Fergus.

What does a Fergus action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (20 Fergus actions page). Cache hits, searches, dry runs and calls Fergus refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Which Fergus API does it cover?

The Fergus API v1 (OpenAPI 3.1.0) at api.fergus.com. It is built from Fergus's documentation as read on 23 October 2026. 91 actions in 23 areas, each one in the signed service file (version 1.0.0).

Can I combine Fergus with my other systems?

Yes. ask joins Fergus to ConnectWise PSA or NetSuite on the same customer and returns the answer rather than every row. Fergus maps crm.company, which 227 other connectors also map.

Does actionlake keep my Fergus data, and where?

actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 5 minutes, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your Fergus credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models.

Which AI clients can use it?

Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names.
