# Basecamp MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Basecamp and the rest of your systems. It gives your agent 262 Basecamp actions (130 reads, 108 writes and 24 that wait for a confirmation) and holds the Basecamp credential itself, so the agent never does. It paces Basecamp's limits and records every call. Connecting Basecamp needs your own Basecamp OAuth app and one admin sign-in.

[Connect Basecamp 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: "basecamp.account.get_account",
  intent: "check which Basecamp account is connected"
}
# Get Account · read · 1 upstream call
```

- 262 actions in one signed file
- 130 read look, never change
- 108 write create and update
- 24 wait for a yes destructive, confirmed first

Set up

## Connect Basecamp 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 Basecamp.
   OAuth 2.0, authorization code. You register your own OAuth app with Basecamp, an admin signs in once, and you paste the app's client id and secret and the tokens from that sign-in; actionlake renews the access token from then on. actionlake stores what you paste write-only, sealed under your tenant's key.
   Before the first sign-in, Basecamp needs an OAuth app of your own, registered in its developer portal. actionlake has no Basecamp app to lend you.
   - `access_token` Access token from one sign-in with your own OAuth app
   - `refresh_token` Refresh token from the same sign-in; the access token is renewed from it
   - `client_id` Basecamp OAuth client ID (from launchpad.37signals.com/integrations)
   - `client_secret` Basecamp OAuth client secret
   - `account_id` Your Basecamp account id
   ```
   account { op: "connections.requirements", service: "basecamp" }
   # 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: "basecamp.account.get_account" }
   # get account · read · 1 upstream call
   check { action: "basecamp.todolists.create_todo", input: { … } }
   # free: inputs, permissions, cost and confirmations, nothing sent
   ```

Top actions

## The Basecamp API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 151 of Basecamp's 155 action names are shared with at least one other connector, so an agent learns them once.

| Action | What it does | Effect | Same name in |
| --- | --- | --- | --- |
| `basecamp.todolists.list_todos` List Todos | List Todos | read | `work.task.list` 122 connectors |

Try it

## Prompts to paste into Claude.

Each one names the Basecamp actions it will call, so you know what it reads and what it changes before you send it.

1. Read read
   Which Basecamp tasks are overdue, and who owns each one?
   calls `basecamp.todolists.list_todos`
2. Plan write
   Spin up a project from a template and wait for it to build in Basecamp. Ask me before anything is sent or changed.
   calls `basecamp.templates.get_template` `basecamp.templates.create_project_from_template` `basecamp.templates.get_project_construction` `basecamp.projects.record_project_visit` `basecamp.projects.get_project`
3. Plan read
   Report each assignable person's workload for the week in Basecamp.
   calls `basecamp.reports.list_assignable_people` `basecamp.reports.get_upcoming_schedule` `basecamp.reports.get_overdue_todos` `basecamp.reports.get_assigned_todos` `basecamp.reports.get_person_progress`
4. Write write
   Create Todo in Basecamp. Show me exactly what you will send before you save it.
   calls `basecamp.todolists.create_todo`
5. Across systems read
   For each customer, how many projects are in Basecamp and how many invoices in ConnectWise PSA?
   calls `basecamp.projects.list_projects` `connectwise_manage.invoices.list`

Across your systems

## Basecamp, joined to the rest of your business.

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

- For each customer, how many projects are in Basecamp and how many invoices in ConnectWise PSA?
  `basecamp.projects.list_projects` + `connectwise_manage.invoices.list`, on `crm.company` · [ConnectWise PSA](https://actionlake.com/connectors/connectwise-psa)
- For each customer, how many projects are in Basecamp and how many invoices in NetSuite?
  `basecamp.projects.list_projects` + `netsuite.views.invoices`, on `crm.company` · [NetSuite](https://actionlake.com/connectors/netsuite)

Also mapped by other connectors `identity.user` **517** `work.project` **116** `work.task` **105** `content.file` **54** `comm.event` **47** `content.document` **17** `comm.message` **15** `work.task_comment` **9**

ask

```
ask {
  intent: "for each customer, how many projects are in Basecamp and how many invoices in ConnectWise PSA",
  steps: [
    { action: "basecamp.projects.list_projects", as: "proj", input: {}, limit: 100, max_pages: 5 },
    { action: "connectwise_manage.invoices.list", as: "inv", input: {}, limit: 100, max_pages: 5 },
    { join: {
        left: "proj",
        right: "inv",
        on: "crm.company",
        group_by: "proj.company_name",
        select: ["proj.company_name", "count(proj.id) as projects", "count(inv.id) as invoices"]
    } }
  ]
}
```

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

The plan store

## Ready-made plans for Basecamp.

9 plans in the store. Install one and your agent runs it by name; the reply says which connections are still missing. A schedule can run a plan on a timetable. There are no triggers or webhooks, by design.

Governance for Basecamp

## Destructive actions wait for a yes.

24 Basecamp actions are destructive. These are all of them:

- Trash Recording `basecamp.recordings.trash_recording`
- Trash Project `basecamp.projects.trash_project`
- Delete Campfire Line `basecamp.campfires.delete_campfire_line`
- Destroy Timesheet Entry `basecamp.timesheets.destroy_timesheet_entry`
- Delete Lineup Marker `basecamp.lineup.delete_lineup_marker`
- Delete Template `basecamp.templates.delete_template`
- Delete Wormhole `basecamp.card_tables.delete_wormhole`
- Disable Project Clients `basecamp.client.disable_project_clients`
- Delete Folder `basecamp.folders.delete_folder`
- Delete Bubble Up `basecamp.recordings.delete_bubble_up`
- Delete Webhook `basecamp.webhooks.delete_webhook`
- Delete Boost `basecamp.boosts.delete_boost`
- Unsubscribe `basecamp.recordings.unsubscribe`
- Unsubscribe From Card Column `basecamp.card_tables.unsubscribe_from_card_column`
- Unpin Message `basecamp.recordings.unpin_message`
- Delete Chatbot `basecamp.campfires.delete_chatbot`
- Destroy Gauge Needle `basecamp.gauges.destroy_gauge_needle`
- Delete Message Type `basecamp.recordings.delete_message_type`
- Deprioritize Assignment `basecamp.my.deprioritize_assignment`

- Remove Account Logo `basecamp.account.remove_account_logo`
- Delete Tool `basecamp.tools.delete_tool`
- Disable Tool `basecamp.recordings.disable_tool`

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.

do basecamp.campfires.delete_campfire_line confirm_policy: **human**

Delete Campfire Line?

**intent:** the user asked me to delete Campfire Line

run suspended · waiting for a named person · key _basecamp-agent_ cannot confirm itself

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

Cost

## What Basecamp costs on actionlake.

- 56 actions page each page of a long list is one call
- 130 reads can be cached a cache hit costs nothing

Questions

## The Basecamp MCP server, answered.

**Is there a Basecamp MCP server for Claude?**

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 262 Basecamp actions across card tables, recordings, my and campfires, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Basecamp.

**What do I need to connect Basecamp?**

Your own Basecamp OAuth app, registered with Basecamp (its client id and client secret), and the access and refresh tokens from one admin sign-in. actionlake has no Basecamp app of its own, so this is not a one-step consent. actionlake renews the access token as it expires. Plus your account id. The free call account { op: "connections.requirements", service: "basecamp" } lists exactly what to paste.

**Can an AI agent delete or change things in Basecamp?**

Only if its key allows it, and only with an explicit confirmation. 24 Basecamp actions are destructive, including trash Recording, trash Project and delete Campfire Line. 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 Basecamp API limit?**

actionlake paces every call to the limits in the Basecamp service file: 50 calls per 10 seconds per connection. Repeated reads are answered from cache (130 Basecamp actions can be), which never reaches Basecamp.

**What does a Basecamp action cost?**

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (56 Basecamp actions page). Cache hits, searches, dry runs and calls Basecamp 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 Basecamp API does it cover?**

The Basecamp 4 (Basecamp 3 API) API bc3 at 3.basecampapi.com, under your account id. It is built from Basecamp's documentation as read on 19 September 2026. 262 actions in 40 areas, each one in the signed service file (version 1.0.0).

**Can I combine Basecamp with my other systems?**

Yes. ask joins Basecamp to ConnectWise PSA or NetSuite on the same customer and returns the answer rather than every row. Basecamp maps work.project, which 116 other connectors also map.

**Does actionlake keep my Basecamp 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 Basecamp 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.
