MCP
Possible nowModel Context Protocol
A standard control panel that can tell an AI what a connected system can do and how to use it.
The labels and controls on the enormous automatic milking machine.
AN IDEAS SHED PROJECT
CowBridge
CowBridge is where The Ideas Shed builds and keeps reusable ways for its Cows, sites and software to talk to other systems — and to each other.
The practical shared workshop and catalogue behind those connections. Build the bridge once. Let the Shed reuse it.
Cow One→CowBridge→Cow Console
WHY IT EXISTS
Being clever is not the same as having the keys to the tractor.
A Cow may know exactly what needs doing. CowBridge develops the shared keys, buttons and connection patterns that let her reach the right software safely.
Prove a useful bridge once, keep its permissions honest, and let multiple Ideas Shed products reuse it instead of rebuilding it.
- Cow One reading Cow Console
- ChatGPT finding a document in Google Drive
- An agent checking Gmail
- A database returning the information a Cow needs
- A tool carrying out an action for an agent
- One system telling another that something changed
A SIMPLE EXAMPLE
“What changed in Cow Console today?”
1
Marcus asks Cow One. Cow One understands the question.
2
To answer properly, she needs a safe way to read Cow Console.
3
The bridge reaches the right information and brings it back.
Cow One→connection→Cow Console→useful information back
CowBridge is not the intelligence. It is how the intelligence reaches what it needs.
WHAT COWBRIDGE EXPLORES
The plumbing, translated into human.
These are useful building ideas, not a vocabulary exam. The human should not have to care about curly brackets.
API
Possible nowApplication Programming Interface
A defined way for one piece of software to ask another for information or to do something.
The service hatch in the side of the machine.
Schema
Possible nowExpected inputs
A description of the information a tool needs — perhaps which project, which date and which person.
The instruction card beside the button.
JSON
Possible nowStructured information
One common machine-readable way for systems to pass organised information to each other.
A tidy little note passed between machines.
SDK
Possible nowSoftware Development Kit
Useful building parts that save a developer manufacturing everything from raw metal. The Agents SDK helps build agents; the Apps SDK helps build capabilities and interfaces for ChatGPT.
A box of useful building bits.
ChatGPT Apps
Possible nowCapabilities inside ChatGPT
A current way to bring external software capabilities and useful interfaces into ChatGPT. Older systems were often called plugins; that is not the framing we rely on here.
Bring the useful machine to where the Cow is already working.
Browser extensions
Possible nowExtra browser capabilities
A small addition to a browser that can sometimes bridge a gap when a website offers no direct connection.
A small tool belt clipped onto the browser.
Authentication + permissions
Possible nowIdentity and authority
Authentication answers ‘Who is this Cow?’ Permissions answer ‘What is this Cow allowed to do?’ Both matter because a connection should not mean access to everything.
She may have a key to the barn but not the medicine cupboard.
Tool calling
Possible nowChoosing to act
An AI can choose a connected capability when it needs that capability to complete the task.
The Cow stops explaining the tractor and actually presses the button.
Webhooks
Possible nowEvents sent back
One system can notify another when something happens instead of being repeatedly asked for an update.
The machine rings a bell when something happens.
MCP is especially useful because it can offer a standard way for AI systems to discover and use external capabilities. It does not replace every API, extension or other practical connection. Sometimes the perfectly good gate is better than building another bridge.
BOTH DIRECTIONS
Sometimes the Cow walks to the machine. Sometimes the machine rings the bell.
The Cow reaches out
Cow One asks Cow Console for information. A ChatGPT Site asks another service to do something useful.
The machine talks back
A service tells Cow Console something changed. An event arrives automatically rather than waiting to be chased.
IDEAS SHED SITES
Build the bridge once. Let the Shed reuse it.
Ideas Shed software and ChatGPT Sites should increasingly be able to talk to each other where that removes friction — rather than becoming isolated little islands or rebuilding the same plumbing.
- Cow Console can know that a new Ideas Shed product exists.
- Cow One can read selected information from another tool.
- A site can expose a genuinely useful action safely.
- Authentication and connection patterns can be sensibly reused.
- Source-of-truth data stays in the right place.
Not everything should be tightly coupled. Connect systems when that removes friction. Keep them separate when that keeps things simpler.
THE COWBRIDGE PRINCIPLE
If we cannot explain the technology reasonably simply, we probably do not understand it well enough yet.
Build once. Reuse across the Shed.
Useful bridges, not pink spaghetti.
We learn enough to understand what matters. We build something when it is actually useful.
Do not build a bridge when there is already a perfectly good gate.
The machinery underneath may be complicated. The human experience should not be.
DOGFOODING
Build it because we need it. Use it. Find the annoying bits. Fix them.
Then — and only then — consider whether someone else might find it useful. CowBridge should not become a giant integration-engineering wormhole. The objective is less friction for humans.
COWBRIDGE TOOL / BRIDGE

THE REST OF THE SHED
Different Cows. Different jobs.
CowBrain
How humans and AI should behave together: truth, judgement, responsibility and what stays human.
How should the Cow behave?Cow Trek
What AI can actually do now, what is changing and what The Ideas Shed should build with it.
What can the Cow do?Cow One
The Ideas Shed’s first AI agent. She works operationally through Cow Console and increasingly needs safe access to other systems.
What needs doing?Cow Console
The central control room and source of truth for what The Ideas Shed is doing.
What is happening in the Shed?CowBridge
How Cows, ChatGPT Sites and Ideas Shed software reach external systems and each other.
How does the Cow reach the machinery?Cowlect
The specialist getting-paid capability: Stripe, Wise, payment readiness and reusable payment components.
How does the money arrive?CowBridge may help connect to a payment service, but payments belong to Cowlect. CowBridge is the broader connection layer; it does not duplicate the getting-paid job.
