Composio

Composio gives AI agents tool-calling across 1,600+ apps with managed per-user auth and secure execution.

82/100Safe BetFree planFreemium

If your agent touches more than one SaaS app on behalf of more than one user, Composio removes the worst part of the job — per-user OAuth, token refresh, and tool-schema sprawl. The Instant Session charge reporting is the detail worth paying for: you see what each run cost in USD instead of guessing. Pass if your agent lives inside a single app whose own SDK already handles auth.

Skip it if

Skip Composio if your agent touches only one app whose own SDK already handles auth, if you need a no-code visual builder like Zapier or Make, or if you require fully self-managed integration infrastructure.

The 30-second take
Biggest gripe

Instant and premium tool execution is billed and metered, so a high-volume agent's per-call charges need monitoring via instantCharge in TypeScript or instant_charge in Python.

Price reality

Composio sells to developer teams that are already paying for an LLM provider, a framework, and cloud hosting, so it sits alongside those line items rather than replacing them. It prices on tool execution and a Zero Data Retention add-on rather than per-seat agent seats, which favors teams running many lightweight per-user Sessions over teams running a few heavy pipelines. Compare it against hand-rolled OAuth connectors (cheap in license, expensive in engineering time) rather than against

About Composio

FreemiumIntermediateAPI availableWeb · API · Plugin · CLI

Composio is developer infrastructure for agents that need to act inside real user accounts, not just chat. Point it at a toolkit and your agent can pull a Gmail thread, open a Linear issue, or fire a Slack message without you writing OAuth flows, token refreshers, or per-service API wrappers. The library spans 1,600+ apps. Tools resolve by intent rather than being dumped into the prompt wholesale. Smart tool search surfaces the right function with the right scope when the agent needs it — useful when a full schema dump would burn your context budget. Auth and context are scoped per end user: OAuth credentials, API keys, and connected accounts are stored against each of your users and refreshed automatically, visible in a Platform Dashboard alongside auth configs, connected accounts, and logs. Reactive agents get triggers: subscribe to events from any toolkit (gmail.message.new, stripe.charge.succeeded, linear.issue.opened) and route them straight to your agent instead of polling. There's also a sandbox pre-wired with that user's connected accounts and the tool library for when the agent needs to compute rather than call. The SDKs are actively shipping — Python SDK 0.28.0 and TypeScript core 0.25.0 added requireApproval on session toolkit, tool, and tag filters, and Python now supports 3.11 through 3.15. Distribution is broad: Python and TypeScript SDKs, a CLI, a hosted MCP endpoint for Cursor, Claude Code, or Codex, and native plugins for those two coding agents. Instant Sessions report exact USD charges in tool execution results, premium usage policies restrict billed execution to specific toolkits, and Zero Data Retention is available as an organization add-on. Composio sits closest to hand-rolled integration code — more setup than a visual connector, but you keep programmatic control over per-user auth and per-call cost reporting.

Behind the Verdict

The pitch is narrow and real: your agent needs to read a user's email, file a ticket, and post a summary, and you don't want to build OAuth plumbing three times. Composio is built for exactly that. We'd reach for it when the agent is multi-app and multi-user, because the per-end-user credential store plus automatic refresh is the part most teams underestimate until a token expires mid-run in production. Two things changed recently that matter for buyers. First, approval gating: SDK 0.28.0 / core 0.25.0 let you set requireApproval on session toolkit, tool, and tag filters, so an agent can be allowed to read a repo but blocked from pushing until a human clicks. Second, Python support now runs to 3.15, which removes a quiet excuse for staying on an old interpreter. Cost visibility is where it separates from visual connectors. Instant Sessions return the exact USD charge in the tool execution result, and premium usage policies let you ring-fence billing to specific toolkits. If you've ever tried to attribute an agent's spend after the fact, that's a real fix. The caveat: this is infrastructure, not a no-code builder. You'll write SDK code, manage sessions, and think about scoping. Work that into your estimate. It also won't bend a standard integration to non-standard API semantics — if a vendor's API is genuinely bespoke, you're writing that wrapper yourself, and Composio just hosts it. Compared to raw integration code, you trade setup time for managed auth, intent-based tool search, triggers, and per-call cost reporting. Compared to Zapier or Make, you get programmatic control and multi-user scope that a visual tool doesn't expose. The hosted MCP endpoint is the low-effort entry point: try it with Cursor or Claude Code before committing to SDK work.

Real-world workflow fit

Concrete scenarios for the personas Composio actually fits — and what changes day-one when you adopt it.

Backend engineer at a 20-person SaaS startup

You need your existing LangChain agent to read each customer's Google Drive and Calendar without building an OAuth vault.

Outcome: Create a Composio Session per end-user, let Composio handle token refresh and connected accounts, and the agent lists files and schedules events against the right user's account within a day.

Founding engineer shipping a support agent

Support tickets arrive in Slack and you want the agent to query Salesforce, open a Jira ticket, and reply in-thread.

Outcome: Subscribe to the Slack trigger, wire the Salesforce and Jira toolkits, and the agent reacts to new messages instead of polling — with tool execution logs for every action in the Platform Dashboard.

Developer using Claude Code or Cursor day to day

You want your coding agent to act on your real Linear and Gmail accounts without leaking credentials into the editor.

Outcome: Install the native Composio plugin, point it at a hosted MCP endpoint, and the agent inherits a scoped Session with per-user auth and the full 1,600+ tool library.

Use Cases

Limitations

  • Composio is a developer platform: the documented paths are SDKs (Python composio 0.28.0, TypeScript @composio/core 0.25.0, plus @composio/slim and a CLI at 0.4.5), framework guides, an API reference with cURL, agent plugins for Codex and Claude Code, and MCP endpoints, so you need development knowledge rather than a visual builder.
  • Any single integration is a generic toolkit, so bespoke API semantics are not the product's focus.
  • The SDK line moves fast — the latest release added session tool approvals and Python 3.15 support, and the changelog notes TypeScript session.executeMeta() signature changes plus new restrictions on identity headers — so version-pinning is a real maintenance task.
  • Session tool execution can require approval via requireApproval filters, so interactive flows need handling for input-required and MCP-no-elicitation fallbacks.
  • The docs name no specific underlying LLM, since Composio supplies tools and integrations rather than a model.

Hidden costs & gotchas

What the public pricing page doesn't put in bold. Captured from pricing-page footnotes, contract terms, and recurring complaints.

  • Instant and premium tool execution is billed and metered, so a high-volume agent's per-call charges need monitoring via instantCharge in TypeScript or instant_charge in Python.
  • Premium usage is disabled by default on a project unless enabled — but passing a policy object on a Session re-enables billing rather than the other way around, so audit Session configs before scaling.
  • Zero Data Retention is an organization add-on billed on a usage-based price, and the changelog notes it is included on Enterprise; if your compliance needs ZDR, factor that into the plan.
  • The SDK rename cadence (0.20.x to 0.22.x in about a week) means migration work — the OpenAI provider dropped Assistants API helpers, so existing Assistants integrations must move to the Responses API.

Where the pricing makes sense

The company stage and team size where Composio's pricing actually pencils out — and where peers do it cheaper.

Composio sells to developer teams that are already paying for an LLM provider, a framework, and cloud hosting, so it sits alongside those line items rather than replacing them. It prices on tool execution and a Zero Data Retention add-on rather than per-seat agent seats, which favors teams running many lightweight per-user Sessions over teams running a few heavy pipelines. Compare it against hand-rolled OAuth connectors (cheap in license, expensive in engineering time) rather than against

Setup time & first value

How long it actually takes to get something useful out of Composio — broken out by persona, not the marketing-page minute.

Backend engineers already inside a Python or TypeScript codebase: first working agent in roughly an afternoon using the Quickstart and framework guides. Teams wiring per-user OAuth and triggers for the first time: one to two days to cover auth configs, connected accounts, and webhook subscriptions. Coding-agent users on Cursor, Claude Code, or Codex: minutes, since the plugin plus hosted MCP

Switching to or from Composio

How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.

Migrating in
  • →From hand-rolled OAuth connectors: replace per-app token stores with Composio Sessions, which refresh OAuth tokens and API keys automatically.
  • →From Zapier or Make: move from visual step-by-step automations to SDK tool calls when agents need per-user auth and programmatic control.
  • →From OpenAI Assistants API helpers: the September 2026 TypeScript release removed them, so move to the Responses API and OpenAIResponsesProvider from @composio/openai.
  • →From the legacy premium_usage / return_premium_charge names: rename to the Instant contract (instant, instantCharge in TypeScript; instant_charge in Python).
Migrating out
  • ↗To a single-app SDK: if your agent only touches one service, that service's own SDK and auth may be enough.
  • ↗To a no-code builder like Zapier or Make: if you need a visual automation editor rather than code, this is a different class of tool.
  • ↗To self-hosted integration infrastructure: Composio's documented paths are SDKs, an API reference, a CLI, and MCP endpoints, not an on-prem install.
