External agents · MCP portal
Connect your AI agents to your brain.
Squirrel Brain has a built-in MCP portal. Point Claude Code, Cursor, or an agent you run yourself at it, and it can set alarms, read your day, file what it finds, and reach you with a message — or a real phone call. Your squirrel becomes the memory layer for the AI tools you already use.
Works with anything that speaks MCP and can send an API key — Claude Code, Claude Desktop, Cursor, and agents you host yourself (OpenClaw, LangChain, your own scripts). Consumer chat apps like ChatGPT can’t connect custom MCP servers yet. And if you never touch any of this: the app does everything on its own.
31 tools your agent can call — the whole set:
Every tool, with parameters, is in the developer docs.
What it can do
Your agent, with hands on your phone.
Set alarms & reminders
Your agent schedules a real alarm on your phone — the same one your squirrel uses, escalation and all.
Read your day
Pull your calendar, open follow-ups, and the morning brief, so an agent can reason about what's actually on your plate.
Call you for real
For the one thing that can't slip, an agent can have your squirrel call your phone — at a set time or right now — a real call that rings through Silent mode, Focus, and a locked screen, on its own, in your squirrel's own voice. Not a notification you'll swipe away.
File to your boards
Drop a note, a link, or a captured item straight onto the right Pix board — it shows up in the app like you snapped it yourself.
Keep a forever note
Append to the running list that never gets erased, so an agent's output sticks around exactly where you'll look for it.
Send a voice message
Have your squirrel speak an agent's message in its own voice — a warm nudge instead of one more line of text.
How it works
Three steps. No glue code.
Generate a key in the app
Open Squirrel Brain and mint a personal API key. It's yours — scoped to your brain, revocable anytime.
Point your agent at the portal
Add the portal to Claude Code, Claude Desktop, or Cursor — or wire it into your own agent. The tools show up automatically — no glue code.
It acts on your brain
Now your agent can set reminders, read your day, file things, and reach you on your terms — every write is traceable to the agent that made it.
Every write is attributed to the agent that made it — so nothing anonymous ever lands in your brain. Read the full tool list and auth flow in the developer docs.
MCP FAQ
Agent questions, answered.
Can Claude or ChatGPT set a reminder or alarm on my phone?
Not on their own — chat assistants can't fire a real, time-based alarm on your iPhone. Squirrel Brain closes that gap two ways: the app itself turns whatever you say, snap, or forward into real alarms — no AI setup needed — and MCP-capable agents like Claude Code, Cursor, or your own agent can drive it directly. ChatGPT can't connect custom MCP servers like this yet.
How does an agent actually do things on my phone?
Through the built-in MCP server. You generate a personal key in the app and connect your agent — Claude Code, Cursor, or one you run yourself. The agent then gets a real tool set: set an alarm, create an item, read your daily brief, append to a forever note, save a link, and trigger a real phone call — and every action it takes is traceable back to the agent that made it.
Which AI tools can connect?
Anything that speaks MCP and can send an API-key header: Claude Code, Claude Desktop, Cursor, and custom agents you host yourself — OpenClaw, LangChain, or plain scripts. Consumer chat apps like ChatGPT can't connect custom MCP tool servers yet.
