Goalpen API — Developer Docs

Quick Start

1

Get an API key

Log in to Goalpen → Settings → API Keys → click New Key. Choose read for read-only access or read + write to allow the AI to create and update items.

2

Point your AI at the discovery URL

Any MCP-compatible client (Claude, Cursor, ChatGPT plugin, custom agent) can read the tool manifest at:
GET https://apitest.goalpen.com/mcp/tools

3

Authenticate with your key

Include the key in every request as a Bearer token:
Authorization: Bearer gp_live_<your-key>

4

Execute a tool

POST to /mcp/execute with { "tool": "list_tasks", "args": {} } — see full reference below.

Available Tools (15)

All tools are scoped to the authenticated user's organisation. Read tools require the read scope; write tools require write.

bulk_update_status

create_blog

Webhooks — Coming Soon

Goalpen will push events to your URL whenever tasks are created, updated, or completed. Configure webhook URLs in Settings → Webhooks.

Event	Fired when
`task.created`	A new task or goal is created
`task.updated`	Any field on a task is changed
`task.completed`	A task's status changes to Completed
`task.status_changed`	Status changes to any value

Authentication

API keys are generated in Goalpen → Settings → API Keys. Keys are prefixed gp_live_ and stored as SHA-256 hashes — the plaintext is shown only once at creation.

Pass the key in every request:

Authorization: Bearer gp_live_<your-key>

Each key is scoped to a single user and organisation. Read keys can only call read tools; write keys can call all tools.
