How to Securely Connect Pi to Arcade for MCP Tools

Pi does not include native MCP support or built-in credential management, so connecting it to external services with local API wrappers can require storing broadly scoped static tokens in configuration files. The guide recommends installing a Pi MCP extension and configuring it to use Arcade.dev as a remote MCP actions runtime, where OAuth-based authorization occurs through browser consent and tokens are stored remotely rather than exposed to Pi or its prompts. It outlines setup steps involving the Pi extension, Arcade CLI, an MCP configuration pointing to Arcade’s HTTPS endpoint, and connection verification within Pi. Arcade is presented as providing hosted tool execution, per-account authorization, persistent action history, and agent-oriented tools for services such as Slack, Jira, Datadog, Gmail, Google Calendar, GitHub, and Linear. Example workflows include converting Slack or Datadog alerts into Jira tickets, producing a morning briefing from unread email and calendar events, and summarizing assigned Linear issues. The guide also addresses common connection and authorization problems, including blocked HTTPS traffic, expired OAuth sessions, insufficient permissions, and the need to complete initial consent interactively before using Pi in non-interactive mode.
