--- title: "Browserbase MCP server for AI agents - actionlake" description: "Give Claude 62 Browserbase actions through one MCP server: sessions, functions, agent. Your agent never holds the credential. 100,000 calls a month free." canonical: https://actionlake.com/connectors/browserbase updated: 2026-10-23 --- Connectors · Developer & infrastructure # Browserbase MCP server for AI agents. actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Browserbase and the rest of your systems. It gives your agent 62 Browserbase actions (38 reads, 12 writes and 12 that wait for a confirmation) and holds the Browserbase credential itself, so the agent never does. It paces Browserbase's limits and records every call. [Connect Browserbase free](https://actionlake.com/console?start=sandbox) [See pricing](https://actionlake.com/pricing) 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. `claude mcp add --transport http actionlake https://connect.actionlake.com/mcp` the first call ``` do { action: "browserbase.projects_list", intent: "check which Browserbase account is connected" } # List Projects · read · 1 upstream call ``` - 62 actions in one signed file - 38 read look, never change - 12 write create and update - 12 wait for a yes destructive, confirmed first Set up ## Connect Browserbase in three steps. 1. 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. `https://connect.actionlake.com/mcp` 2. 02 ### Connect Browserbase. API key. 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_key` Browserbase API key ``` account { op: "connections.requirements", service: "browserbase" } # free: exactly what to paste, and what is found for you ``` 3. 03 ### 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. ``` do { action: "browserbase.projects_list" } # list projects · read · 1 upstream call check { action: "browserbase.secrets_create", input: { … } } # free: inputs, permissions, cost and confirmations, nothing sent ``` Browserbase at a glance **Sign-in** API key.

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. do browserbase.secrets_delete confirm_policy: **human** Delete a Secret? **intent:** the user asked me to delete a Secret run suspended · waiting for a named person · key _browserbase-agent_ cannot confirm itself In the console, or from an emailed signed link. a key for this connector ``` account { op: "keys.create", name: "browserbase-agent", allowed_actions: ["browserbase.*"], cap_calls: 2000, confirm_policy: "human_for_writes", approval_rules: [ { match: "browserbase.secrets_delete", approver: "lead@example.com" }, { match: "browserbase.certificates_delete", approver: "lead@example.com" }, { match: "browserbase.webhooks_delete", approver: "lead@example.com" } ] } ``` Illustrative.

The free call account { op: "connections.requirements", service: "browserbase" } lists exactly what to paste. **Can an AI agent delete or change things in Browserbase?** Only if its key allows it, and only with an explicit confirmation. 12 Browserbase actions are destructive, including delete a Secret, delete a Certificate and delete a Webhook. 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 Browserbase API limit?** actionlake paces every call to the limits in the Browserbase service file: 600 calls a minute per connection. Repeated reads are answered from cache (29 Browserbase actions can be), which never reaches Browserbase. **What does a Browserbase action cost?** One upstream call, the only unit actionlake bills. A list that pages bills one call per page (62 Browserbase actions page). Cache hits, searches, dry runs and calls Browserbase 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 Browserbase API does it cover?** The Browserbase API v1 (OpenAPI 3.0.0) at api.browserbase.com. It is built from Browserbase's documentation as read on 23 October 2026. 62 actions in 15 areas, each one in the signed service file (version 1.0.0). **Does actionlake keep my Browserbase data, and where?** actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 15 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 Browserbase 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. ## More connectors like Browserbase Shares the most action names with - [Bitrise 9](https://actionlake.com/connectors/bitrise) - [CircleCI 9](https://actionlake.com/connectors/circleci) - [Apify 7](https://actionlake.com/connectors/apify) - [DNSimple 6](https://actionlake.com/connectors/dnsimple) - [Exa 6](https://actionlake.com/connectors/exa) - [Porkbun 5](https://actionlake.com/connectors/porkbun) Joins with, on shared entities - [Slack 2](https://actionlake.com/connectors/slack) - [LlamaCloud 2](https://actionlake.com/connectors/llamacloud) - [Gusto 1](https://actionlake.com/connectors/gusto) - [Microsoft 365 Users 1](https://actionlake.com/connectors/microsoft-365-users) - [Cloudflare 1](https://actionlake.com/connectors/cloudflare) - [NetBox 1](https://actionlake.com/connectors/netbox) Browse - [All Developer & infrastructure connectors](https://actionlake.com/connectors/category/developer-and-infrastructure) - [All connectors](https://actionlake.com/connectors) - [How actionlake compares](https://actionlake.com/compare) actionlake is independent.
