When not to use it

Skip Coinbase Automation when the task is outside the productivity category, or when a more specific skill in this directory already covers the same workflow with clearer triggers.

How to install

1. Personal install: create ~/.claude/skills/coinbase-automation/SKILL.md (and any bundled scripts) so Claude Code, Claude Desktop, and compatible agents can load it in every project.
2. Project install: commit the same folder at .claude/skills/coinbase-automation/ so teammates get the skill with the repo.
3. Restart the agent session after copying files so it re-scans the skills directory, then ask for the task in words that match the skill description.

What this skill does

# Coinbase Automation

Automate Coinbase operations including listing cryptocurrency wallets, paginating through wallet collections, and retrieving portfolio data.

**Toolkit docs:** [composio.dev/toolkits/coinbase](https://composio.dev/toolkits/coinbase)

---

## Setup

This skill requires the **Rube MCP server** connected at `https://rube.app/mcp`.

Before executing any tools, ensure an active connection exists for the `coinbase` toolkit. If no connection is active, initiate one via `RUBE_MANAGE_CONNECTIONS`.

---

## Core Workflows

### 1. List All Wallets

Retrieve all wallets from Coinbase with pagination support.

**Tool:** `COINBASE_LIST_WALLETS`

**Key Parameters:** - `limit` -- Results per page (1--100, default: 25) - `order` -- Sort order: `"asc"` (ascending) or `"desc"` (descending, default) - `starting_after` -- Cursor for forward pagination: ID of the last wallet from the previous page - `ending_before` -- Cursor for backward pagination: ID of the first wallet from the previous page

**Example (first page):** ``` Tool: COINBASE_LIST_WALLETS Arguments: limit: 50 order: "desc" ```

**Example (next page):** ``` Tool: COINBASE_LIST_WALLETS Arguments: limit: 50 order: "desc" starting_after: "wallet_abc123_last_id_from_prev_page" ```

---

### 2. Paginate Through All Wallets

To retrieve a complete wallet inventory, iterate through pages.

**Steps:** 1. Call `COINBASE_LIST_WALLETS` with desired `limit` and `order` 2. If the response contains more results, note the ID of the last wallet returned 3. Call `COINBASE_LIST_WALLETS` again with `starting_after` set to that last wallet ID 4. Repeat until no more results are returned

---

### 3. Audit Wallet Portfolio

Retrieve wallet data for portfolio analysis and reporting.

**Steps:** 1. Call `COINBASE_LIST_WALLETS` with `limit: 100` to maximize per-page results 2. Collect wallet balances and metadata from each page 3. Aggregate data across all pages for a complete portfolio view

---

### 4. Monitor Wallet Changes

Periodically list wallets to detect new additions or changes.

**Steps:** 1. Call `COINBASE_LIST_WALLETS` with `order: "desc"` to get newest wallets first 2. Compare against previously stored wallet IDs to identify new entries 3. Schedule periodic checks for continuous monitoring

## Known Pitfalls

| Pitfall | Detail | |---------|--------| | **Pagination required** | Wallet lists are paginated. Always check for additional pages using cursor-based pagination (`starting_after`/`ending_before`). | | **Limit bounds** | The `limit` parameter accepts 1--100. Values outside this range cause errors. Default is 25. | | **Cursor-based pagination** | Uses wallet IDs as cursors, not page numbers. You must extract the last/first wallet ID from each response to navigate pages. | | **CDP SDK scope** | This tool uses the Coinbase CDP SDK. Available operations depend on the API key permissions granted during connection setup. |
