A DIY project MCP that knows what is on your workbench
Chat assistants are good at talking through a build and bad at remembering yours. This MCP for home projects connects Claude or ChatGPT to the projects you keep in Blueprint, so a question about the deck starts from the deck you are actually building.
What it looks like mid-project
“Which steps are left on the deck rebuild, and what have I spent so far?”
list_projects and get_project read the steps and every logged expense.
“Compare the two quotes on the bathroom remodel.”
get_project returns the contractor quotes and their line items.
“Start a project called Garage shelving at the main house.”
create_project opens it once your client gets your approval.
Connect it in about a minute
MCP is included with Blueprint Pro, so you need Pro on the workspace that holds your projects. Both clients use this server address:
https://blueprinthome.app/api/mcpIn Claude
- Go to Settings, Connectors, Add custom connector.
- Paste the address, then press Connect.
- Sign in to Blueprint and choose the workspace your projects live in.
In ChatGPT
- Go to Settings, then Apps and Connectors, and turn on developer mode under Advanced if custom connectors are hidden.
- Add a new connector with the address and OAuth authentication.
- Sign in to Blueprint and choose the workspace.
Leave “make changes” unticked if you only want it to read. Menus and plan requirements belong to each client and can change. Remove access any time from Connected apps in Blueprint's settings.
Questions
What does a DIY project MCP do?
It lets an AI assistant work from your real project data over the Model Context Protocol. Through Blueprint, Claude or ChatGPT can see the steps, costs and quotes on your builds rather than asking you to paste them in.
Is this MCP for home projects free?
The calculators and cheat sheets on DIYProject.ai are free. The MCP server is included with Blueprint Pro ($7.99 a month or $49.99 a year, with a 7-day free trial on the annual plan). A workspace not on Pro cannot connect or use it. If a subscription lapses, the connection is kept and works again when you resubscribe.
Can it write a full project plan?
Not through this server. create_project opens a project with a name and description, and it starts with no plan. Your assistant can talk the plan through with you, and Blueprint's own AI planner generates plans inside the app.
Does it see my calculator results?
No. Calculators on this site run in your browser and are not connected to your Blueprint account. The server reads what is saved in Blueprint.
Will it see a project a housemate marked private?
No. Private projects are visible only to the member who created them, and the same rule applies to anything connected under your account.
