Tools and sign-in for AI agents
Tools and auth for AI agents. Dexby gives agents secure access to 1,000+ apps, handling credentials, OAuth, tool search, and execution so every action runs as the right user and is audited.
the problem
Every team building AI agents ends up writing the same integration layer: OAuth flows, token refresh, credential storage, per-user scoping, and tool schemas for each app the agent needs to touch.
→ the approach
- Built a TypeScript SDK that plugs into the agent frameworks teams already use: Vercel AI SDK, Mastra, LangChain, OpenAI Agents, Anthropic, and Gemini.
- Scoped every tool call to a user session, so actions run as the right user with the right connection and scopes.
- Handled the unglamorous parts centrally: encrypted credentials, OAuth refresh and revocation, scope enforcement, authenticated proxying, triggers, and webhooks.
- Exposed the same catalog over MCP and let teams import their own MCP servers and OpenAPI specs.
what shipped
- 1,000+ connectors and about 7,500 tool definitions
- Tool search and execution with per-user session isolation
- Hash-chained audit log for every action
