Introduction

Foundry is an AI-native developer platform that gives your apps and tools persistent context, security scanning, and first-class Cursor integration via MCP.

​
Three pillars

Memory Engine

Persistent AI context API backed by pgvector semantic search. Write, search, and inject context into prompts.

Security Scanner

AI-powered vulnerability detection for repos. Scan on demand or in CI; get actionable findings.

MCP Integration

Use Foundry from Cursor via @withfoundry/mcp-server. Memory and security tools in the IDE.

​
How it works

  • API: REST at https://api.withfoundry.ai. All responses use the envelope { success, data, meta: { requestId } }.
  • Auth: API keys with prefix key_ sent as Authorization: Bearer key_....
  • SDK: @withfoundry/sdk for Node/TypeScript.
  • MCP: @withfoundry/mcp-server for Cursor and other MCP clients.
