Crunchbase MCP server for AI agents.
actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Crunchbase and the rest of your systems. It gives your agent 112 Crunchbase actions (112 reads and 0 writes) and holds the Crunchbase credential itself, so the agent never does. It paces Crunchbase'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 Crunchbase 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.

The Crunchbase API, shaped for agents.

Governance for Crunchbase
Every write can wait for a yes.
None of Crunchbase's actions is destructive. A key can still be held to reads, capped, and set so a person confirms every write.
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.
account { op: "keys.create", name: "crunchbase-agent", allowed_actions: ["crunchbase.*"], cap_calls: 2000, confirm_policy: "human_for_writes"}Cost
What Crunchbase costs on actionlake.
Every Crunchbase action is one upstream call, the only thing actionlake bills. Searching, check, cost, account and any call Crunchbase 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 Crunchbase MCP server, answered.
Is there a Crunchbase MCP server for Claude?
Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 112 Crunchbase actions across acquisitions, addresses, categories and category groups, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Crunchbase.
What do I need to connect Crunchbase?
Crunchbase API key (Enterprise or API licence): crunchbase.com > Account > Integrations > Crunchbase API. The free call account { op: "connections.requirements", service: "crunchbase" } lists exactly what to paste.
Will an AI agent use up my Crunchbase API limit?
actionlake paces every call to the limits in the Crunchbase service file: 200 calls a minute per connection. Repeated reads are answered from cache (112 Crunchbase actions can be), which never reaches Crunchbase.
What does a Crunchbase action cost?
One upstream call, the only unit actionlake bills. A list that pages bills one call per page (112 Crunchbase actions page). Cache hits, searches, dry runs and calls Crunchbase 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 Crunchbase API does it cover?
The Crunchbase API v4 (data.crunchbase.com reference, all data packages) at api.crunchbase.com/v4. It is built from Crunchbase's documentation as read on 23 October 2026. 112 actions in 48 areas, each one in the signed service file (version 1.0.0).
Does actionlake keep my Crunchbase 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 Crunchbase 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.
