Reply.io MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Reply.io and the rest of your systems. It gives your agent 416 Reply.io actions (160 reads, 190 writes and 66 that wait for a confirmation) and holds the Reply.io credential itself, so the agent never does. It paces Reply.io's limits and records every call.

Set up

Connect Reply.io 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 Reply.io.
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_keyReply API key
```
account { op: "connections.requirements", service: "reply_io" }
# 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 Reply.io API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 54 of Reply.io's 54 action names are shared with at least one other connector, so an agent learns them once.

Across your systems

Reply.io, joined to the rest of your business.

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

Which Reply.io companies have invoices in ConnectWise PSA, and how many each?
reply_io.contact_accounts.list + connectwise_manage.invoices.list, on crm.company · ConnectWise PSA

ask {  intent: "which Reply.io companies have invoices in ConnectWise PSA, and how many each",  steps: [    { action: "reply_io.contact_accounts.list", as: "co", input: {}, limit: 100, max_pages: 5 },    { action: "connectwise_manage.invoices.list", as: "inv", input: {}, limit: 100, max_pages: 5 },    { join: {        left: "co",        right: "inv",        on: "crm.company",        group_by: "co.name",        select: ["co.name", "count(inv.id) as invoices"]    } }  ]}

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

Governance for Reply.io

Destructive actions wait for a yes.

66 Reply.io actions are destructive. The first 10:

Delete a contactreply_io.contacts.delete
Delete an accountreply_io.contact_accounts.delete
Delete an email accountreply_io.email_accounts.delete
Delete an email templatereply_io.email_templates.delete
Delete a sequencereply_io.sequences.delete
Delete a taskreply_io.tasks.delete
Delete a webhook subscriptionreply_io.webhooks.delete
Cancel a background jobreply_io.background_jobs.cancel
Delete a voicereply_io.voices.delete
Delete a schedulereply_io.schedules.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.

doreply_io.contacts.deleteconfirm_policy: human

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

Cost

What Reply.io costs on actionlake.

Every Reply.io action is one upstream call, the only thing actionlake bills. Searching, check, cost, account and any call Reply.io 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.

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.
