Codapult MCP
Your AI agent shouldn’t have to understand your codebase from scratch.
Most coding agents start with files. Codapult MCP gives your agent structured access to the architecture behind them.
Understand the architecture
Give agents the project map, conventions and boundaries before they change code.
Work from real context
Connect schema, environment and product modules to the task at hand.
Repeat the right workflow
Move from discovery to implementation and validation with a shared project context.

A safer way to change your codebase
Make changes that fit the system.
Your agent doesn't just generate code. It works within your Codapult project's architecture, conventions and available capabilities.
Explore the CLI workflowAdapter architecture
Your business logic shouldn’t care which vendor you choose.
Keep your product code readable and your infrastructure replaceable — so you can change providers when your product, budget or deployment needs change.
Swap the provider. Keep your product code.
Infrastructure changes stay contained instead of becoming rewrites across every screen and server action.
