Short Story
Origin
ShapeMCP started as an internal friction-reduction tool for the Inevitable AI team. We found that LLMs often hallucinate or produce incorrect tool call payloads when they don’t have a pixel-perfect JSON schema for each tool.
The problem
Asking an AI to “guess” the schema of an API or a function leads to mismatches: wrong parameter names, wrong types, or missing required fields. That causes failed tool calls, retries, and poor user experience. Manually maintaining JSON Schema for every tool is tedious and error-prone.
The solution
We built a deterministic engine that guarantees accuracy by reading the actual shape of your code and data. By automating the bridge between your codebase and AI agents, developers spend less time on boilerplate and more time on agent logic and product.
