Factorly lets you build REST, CLI, and MCP tools in a web UI, chain them into workflows, and hand them to your agent with credentials and policies already locked down.
Real services, no filler.
Define REST APIs, CLI commands, or MCP servers in one config, or import an OpenAPI spec directly.
Chain multiple tools into a multi-step workflow with per-step policies, then expose the whole thing as a single callable tool.
Credentials and permissions ship with the runtime, so what an agent can touch stays explicit and controlled.
Every tool call and workflow run gets logged, giving you a clear record of what your agents actually did.
Over 40 ready-made integrations, including GitHub, Slack, Stripe, and Notion, install with a single command.
Representative imagery only.
Factorly is an open-source, locally run workbench for building and managing the tools AI agents use. Teams define tools for REST APIs, CLI commands, or MCP servers, test them in a web interface, and chain them into multi-step workflows, all stored in a .factorly/ directory that travels with the repo. It works with Claude Code, Cursor, Codex, and any client that speaks MCP.
