Plain MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Plain and the rest of your systems. It gives your agent 523 Plain actions (202 reads, 234 writes and 87 that wait for a confirmation) and holds the Plain credential itself, so the agent never does. It paces Plain's limits and records every call.

Set up

Connect Plain 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.

02
Connect Plain.
Bearer token. No consent screen: your agent can connect it for you, but the key then passes through your chat. To keep it out of the model's context, paste it in the console instead. actionlake stores what you paste write-only, sealed under your tenant's key.
- api_keyPlain API key (plainApiKey_...)
```
account { op: "connections.requirements", service: "plain" }
# free: exactly what to paste, and what is found for you
```

Make the first call. Check before a write.

Ask in plain words; Claude picks the action. Before anything changes, check validates the call and prices it, for free.

Top actions

The Plain API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 24 of Plain's 24 action names are shared with at least one other connector, so an agent learns them once.

Each one names the Plain actions it will call, so you know what it reads and what it changes before you send it.

Across your systems

Plain, joined to the rest of your business.

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

ask

ask {  intent: "for each customer, how many tickets are in Plain and how many invoices in ConnectWise PSA",  steps: [    { action: "plain.thread.list", as: "tix", input: {}, limit: 100, max_pages: 5 },    { action: "connectwise_manage.invoices.list", as: "inv", input: {}, limit: 100, max_pages: 5 },    { join: {        left: "tix",        right: "inv",        on: "crm.company",        group_by: "tix.company_name",        select: ["tix.company_name", "count(tix.id) as tickets", "count(inv.id) as invoices"]    } }  ]}

Example. Run it through check first: it validates the steps and prices them, and it is free.

Governance for Plain

Destructive actions wait for a yes.

87 Plain actions are destructive. The first 10:

Plain customer: deleteplain.customer.delete
Plain account: deleteplain.account.delete
Plain user: deleteplain.user.delete
Plain thread: deleteplain.thread.delete
Plain task: deleteplain.task.delete
Plain note: deleteplain.note.delete
Plain tier: deleteplain.tier.delete
Plain label: removeplain.label.remove
Plain tenant: deleteplain.tenant.delete
Plain api key: deleteplain.api_key.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.

doplain.customer.deleteconfirm_policy: human

In the console, or from an emailed signed link.

Illustrative. Scoped to Plain only, capped at 2,000 upstream calls, every write confirmed, and the destructive ones approved by a named person.

Cost

What Plain costs on actionlake.

Every Plain action is one upstream call, the only thing actionlake bills. Searching, check, cost, account and any call Plain refused with 401, 403, 429 or a 5xx are free. 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.

Questions

The Plain MCP server, answered.

Is there a Plain MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 523 Plain actions, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Plain.

What do I need to connect Plain?

Plain API key (plainApiKey_...). The free call account { op: "connections.requirements", service: "plain" } lists exactly what to paste.

Can an AI agent delete or change things in Plain?

Only if its key allows it, and only with an explicit confirmation. 87 Plain actions are destructive, including plain customer: delete, plain account: delete and plain user: delete. 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 Plain API limit?

actionlake paces every call to the limits in the Plain service file: 600 calls a minute per connection. Repeated reads are answered from cache (200 Plain actions can be), which never reaches Plain.

What does a Plain action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (72 Plain actions page). Cache hits, searches, dry runs and calls Plain 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 Plain API does it cover?

The Plain API graphql-v1 at core-api.uk.plain.com. It is built from Plain's documentation as read on 23 October 2026. 523 actions in 1 area, each one in the signed service file (version 1.0.0).

Can I combine Plain with my other systems?

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

Does actionlake keep my Plain data, and where?

actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to an hour, 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 Plain 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.
