For developers
You can grow your own audience with The Foundry
Programs connect you to houses, hosts, and peers. Content Lab and cohort rhythm adapt to how you already build no new integration layer required API or framework:
Anthropic
Use The Foundry with the Claude Messages API or the Claude Agent SDK.
OpenAI
Use The Foundry with the Responses API, Chat Completions API, or OpenAI Agents SDK. For other OpenAI-compatible APIs, your provider must support the tool-calling format you use.
Vercel AI SDK
Add The Foundry tools with built-in execution so the AI SDK can run tool calls for you.
LangGraph
Use our official Python package to turn The Foundry tools into LangChain tools that work in LangGraph workflows.
Everything else
The Foundry works wherever builders meet: houses, Discord, and cohort calls
The Foundry provides a hosted MCP server that gives your harness access to its app integrations. If your harness supports the ability to connect to remote MCP servers, you can connect it to The Foundry.
