Bandwidth MCP server for AI agents.
actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Bandwidth and the rest of your systems. It gives your agent 518 Bandwidth actions (285 reads, 171 writes and 62 that wait for a confirmation) and holds the Bandwidth credential itself, so the agent never does. It paces Bandwidth's limits and records every call.
100,000 free calls a month. No card, no email, no password: press Start a free sandbox on the next screen and keep the key it shows you.

Set up
Connect Bandwidth 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.

Connect Bandwidth.
OAuth 2.0, client credentials. Paste the app's client id and secret; actionlake fetches and renews the token, and nobody has to sign in. actionlake stores what you paste write-only, sealed under your tenant's key.

Top actions
The Bandwidth API, shaped for agents.
The ids your agent types, what each does, and the one name it shares with other systems. 22 of Bandwidth's 22 action names are shared with at least one other connector, so an agent learns them once.

Governance for Bandwidth
Destructive actions wait for a yes.
62 Bandwidth actions are destructive. The first 10:
- Delete Recording
bandwidth.voice.delete_recording - Delete Client Credentials
bandwidth.client_credentials.delete_client_credentials - Delete a brand from the account.
bandwidth.tendlc.delete_brand - Delete Media
bandwidth.messaging.delete_media - Delete Location
bandwidth.accounts.delete_location - Deactivate a campaign
bandwidth.tendlc.deactivate_campaign - Delete Sub-Account
bandwidth.accounts.delete_sub_account - Delete Recording Media
bandwidth.voice.delete_recording_media - Delete Real-time Transcription
bandwidth.voice.delete_real_time_transcription - Delete Transcription
bandwidth.voice.delete_recording_transcription
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.

What Bandwidth costs on actionlake.
Every Bandwidth action is one upstream call, the only thing actionlake bills. Searching, check, cost, account and any call Bandwidth 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 Bandwidth MCP server, answered.
Is there a Bandwidth MCP server for Claude?
Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 518 Bandwidth actions across number management, hosted numbers, product settings and emergency, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Bandwidth.
What do I need to connect Bandwidth?
Bandwidth API client ID (Bandwidth App > Account > API Credentials) and Bandwidth API client secret paired with the client ID (shown once, when the credentials are created). Plus your account id. The free call account { op: "connections.requirements", service: "bandwidth" } lists exactly what to paste.
Can an AI agent delete or change things in Bandwidth?
Only if its key allows it, and only with an explicit confirmation. 62 Bandwidth actions are destructive, including delete Recording, delete Client Credentials and delete a brand from the account.. 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 Bandwidth API limit?
actionlake paces every call to the limits in the Bandwidth service file: 50 calls a second per connection. Repeated reads are answered from cache (278 Bandwidth actions can be), which never reaches Bandwidth.
What does a Bandwidth action cost?
One upstream call, the only unit actionlake bills. A list that pages bills one call per page (518 Bandwidth actions page). Cache hits, searches, dry runs and calls Bandwidth 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 Bandwidth API does it cover?
The Bandwidth: messaging (SMS/MMS, multi-channel), voice calls, conferences, recordings and transcriptions, MFA codes, phone number lookup, number ordering, porting and hosted numbers, 10DLC brands and campaigns, toll-free verification, short codes, 911 emergency provisioning, insights, users and account management API Bandwidth per-product OpenAPI specs (dev.bandwidth.com/spec, fetched 2026-10-23) at api.bandwidth.com. It is built from Bandwidth's documentation as read on 23 October 2026. 518 actions in 41 areas, each one in the signed service file (version 1.0.0).
Does actionlake keep my Bandwidth 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 Bandwidth 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.
