6sense MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to 6sense and the rest of your systems. It gives your agent 9 6sense actions (9 reads and 0 writes) and holds the 6sense credential itself, so the agent never does. It paces 6sense's limits and records every call.

Set up

Connect 6sense 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.

  2. 02

    Connect 6sense.

    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.

    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 6sense API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 1 of 6sense's 1 action names are shared with at least one other connector, so an agent learns them once.

Governance for 6sense

Every write can wait for a yes.

None of 6sense'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.

a key for this connector
account {  op: "keys.create", name: "sixsense-agent",  allowed_actions: ["sixsense.*"], cap_calls: 2000,  confirm_policy: "human_for_writes"}
Illustrative. Scoped to 6sense only, capped at 2,000 upstream calls, every write confirmed.

Cost

What 6sense costs on actionlake.

Every 6sense action is one upstream call, the only thing actionlake bills. Searching, check, cost, account and any call 6sense 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 6sense MCP server, answered.

Is there a 6sense MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 9 6sense actions, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by 6sense.

What do I need to connect 6sense?

6sense API token (6sense Platform > Settings > API Token Management > Generate New API Token; pick the API group…. The free call account { op: "connections.requirements", service: "sixsense" } lists exactly what to paste.

Will an AI agent use up my 6sense API limit?

actionlake paces every call to the limits in the 6sense service file: 100 calls a minute per connection. Repeated reads are answered from cache (8 6sense actions can be), which never reaches 6sense.

What does a 6sense action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (2 6sense actions page). Cache hits, searches, dry runs and calls 6sense 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 6sense API does it cover?

The 6sense APIs (company firmographics, lead scoring, people enrichment, people search) API v1/v2 (per endpoint) at api.6sense.com. It is built from 6sense's documentation as read on 23 October 2026. 9 actions in 1 area, each one in the signed service file (version 1.0.0).

Can I combine 6sense with my other systems?

Yes. ask joins 6sense to ConnectWise PSA or NetSuite on the same customer and returns the answer rather than every row. 6sense maps crm.company, which 227 other connectors also map.

Does actionlake keep my 6sense 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 6sense 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.
