FunctionFoundry / Agent capability economics

Should the agent build it, integrate it, or buy it?

Web · REST · MCP · Available by request

FunctionFoundry estimates the tokens required to build equivalent functionality, then compares that cost with integration and purchase options before an agent writes code.

Inside the capability decision

Compare every path before generation.

Compile the requirements once, price equivalent build effort as a range, test integration and acquisition constraints, and return a decision an agent can act on without hiding uncertainty.

Before generation begins

Compare build, integration, and purchase before generation.

FunctionFoundry gives coding agents a structured economic decision at planning time. Requirements, rights, deployment constraints, build effort, integration work, and operating cost become part of the plan before generation begins.

Decision sequence

One capability. One fair comparison across every path.

01

Compile the capability

Turn the request into features, runtime, deployment, rights, security, price, and operating requirements before an option is ranked.

02

Map credible options

Compare build, acquire, integrate, compose, and stop paths against the same hard requirements and acceptance surface.

03

Estimate equivalent build cost

Estimate the tokens and engineering effort required to build equivalent functionality, then compare integration, review, runtime, and ownership cost.

04

Return the economic decision

Recommend build, acquire, compose, stop, or evaluate further with the assumptions and next action attached.

Decision interfaces

Built for agents and the operators who govern them.

The same comparison can enter through a guided web flow, a structured REST request, or an MCP tool call and return an evidence-linked, organization-scoped record.

MCP

Let an agent request a capability comparison directly inside its planning loop.

REST

Send a structured capability request and receive requirements, options, estimates, recommendation, and next actions.

Web

Let a human inspect assumptions, rights coverage, sensitivities, and next steps before execution moves forward.
