Gram Functions

What is Gram Functions?

Gram Functions is an open-source platform component designed to help developers create and manage tools for AI agents. Built by the Gram team, it extends Gram's core functionality beyond OpenAPI document uploads by enabling users to define, curate, and deploy custom functions that agents can utilize. The platform serves developers and teams building AI agent applications who need a structured way to organize and version-control tool definitions. Rather than manually converting API documentation, Gram Functions provides a standardized approach to function curation and management within the Gram ecosystem. Key aspects of Gram Functions include support for custom function definitions, integration with agent workflows, and the ability to package functions for reuse across projects. The open-source nature allows developers to inspect, modify, and contribute to the codebase. Gram Functions is particularly suited for teams that require granular control over which functions their agents can access, need to maintain consistency across multiple agent deployments, or want to build custom tooling without vendor lock-in. It fits into the broader landscape of AI infrastructure tools focused on agent capability management and orchestration.
