Open-source tools & agent skills to build the things you’re paying for.

Composio

Project30.5K

Build agents that discover and use connected app tools through SDKs, provider adapters, or a CLI.

What you can build

  • Build a daily brief that takes a date window, retrieves connected email content, groups messages by urgency, and outputs a prioritized summary.
  • Build a report generator that takes a project name, gathers relevant connected-app records, normalizes status and risks, and outputs a concise update.
  • Build a CLI workflow that takes a research question, searches for and runs selected tools, evaluates results against a criterion, and outputs a decision-ready brief.
  • Build a prep-sheet generator that takes a meeting and its time, gathers relevant connected calendar and email context, and outputs an attendee-focused brief.
  • Build an agent that takes a ticket, retrieves relevant connected-account context, and outputs a response draft and action plan while leaving the original ticket unchanged.

Try this prompt

Build a small TypeScript support-triage workflow using Composio and a documented agent provider. Accept a support ticket as input, create a user-scoped session, and use connected tools to gather relevant account context. Return a concise response draft and proposed next actions; do not modify the ticket or connected records. Preserve the original ticket and show which retrieved details informed the draft. Use only documented SDK interfaces, include setup and error handling, and keep secrets out of source control.

Get started

  1. Choose a runtime

    The README documents TypeScript on Node 22+ and Python 3.10+. Select the SDK and an agent framework with a listed provider adapter, or use the CLI.

  2. Get an API key

    The quickstart requires a COMPOSIO_API_KEY, available from the Composio dashboard settings linked in the README.

  3. Create a user-scoped session

    Follow the TypeScript or Python quickstart to create a session, obtain its tools, and pass them to an agent. The README also documents CLI login, search, execute, and scripted workflows.

License & notes

MITThe repository is MIT licensed. A Composio API key is required for the documented quickstart. Budget separately for any Composio-hosted services, model/API usage, connected application services, and your own hosting; the supplied evidence provides no prices or free-tier terms.

  • Composio provides tool access and SDK adapters, not a complete end-user workflow or business application.
  • The quickstart requires an API key; model, service, connected-app, and hosting costs are separate and unspecified in the supplied evidence.
  • Connected tools, account permissions, and provider support determine what each agent can do; review tool access before enabling actions.
