About Composio
Composio connects your AI assistant to the apps you use for work. It gives tools like Claude, ChatGPT and Hermes access to Gmail, Slack, Notion, GitHub and a catalog of more than 1,500 apps, so you can ask them to do things across those services from one conversation.
I'd consider it if your assistant is useful for thinking and writing, but you still spend time moving the results into other apps. Composio handles the connections and gives the agent a way to find and run the actions a task needs.
You can connect an existing assistant without building your own software. Developers can also use Composio's platform to add app integrations to a product, including authentication for its users.
Try Composio with your AI assistant.
What is Composio?
Composio is an integration platform for AI agents. Your assistant interprets the request, and Composio provides access to connected apps through tools, managed authentication and an execution service.
For example, an agent could find open GitHub issues and use the results to create a project update in another connected app. A sales assistant could work with CRM records and email. The available actions depend on the app, the account permissions and the assistant you connect.
Composio has two main entry points. Composio For You connects an assistant you already use through a supported connector, MCP server or plugin. Composio Platform gives developers SDKs and APIs for building those capabilities into their own agents.
MCP is the protocol that lets compatible AI clients use external tools. Composio's hosted MCP connection provides access to its catalog without requiring a separate server configuration for every app.
Who is Composio For?
Composio is a good fit for people who already use AI and want it involved in more of their working process. That could mean finding information in connected accounts, preparing updates or taking actions across several business apps.
For creators and small teams, the appeal is having one assistant work across the tools already in use. You can keep your existing email, documents and project software rather than moving everything into a new workspace.
If you run Hermes Agent or OpenClaw, Composio is a complementary service for app access. The agent still manages the conversation and its own workflow; Composio supplies integrations.
Developers have a different reason to use it: maintaining OAuth connections and individual app integrations takes work. Composio provides that infrastructure so a team can spend more time on the product those integrations support.
I would start with the assistant's built-in connections if they already cover everything you need. Composio becomes more useful when you need broader app access, multiple connected accounts or integrations you can reuse across assistants.
Composio Pros and Cons
Composio Features: App Connections, Tool Discovery and Agent Workflows
Connect the assistant you already use
Composio supports popular assistants and agent environments, including Claude, ChatGPT, Codex, Cursor and Hermes. The connection method depends on the client. Some use a hosted MCP endpoint, while native plugins are available for Claude Code and Codex.
You authorize the apps you want the agent to access, and Composio keeps those connections available for later sessions. It also supports multiple accounts for the same app, which is useful when work spans separate projects or businesses.
Client requirements still apply. An assistant may require a particular plan or connector setting to accept an external integration.
Find tools when a task needs them
A large integration catalog creates a practical problem: giving the model every available action at once would fill its context with tools it does not need.
Composio lets the agent search for suitable actions and load their definitions on demand. A request about calendar availability can bring in calendar tools; a request about a repository can bring in GitHub tools.
This is one of its more useful design choices. You get access to a broad catalog without having to configure a fixed collection of actions for every conversation.
Managed authentication
Composio handles OAuth consent, token storage and refresh for supported connections. Users approve access to their accounts, and the service manages the credentials needed to execute tools.
For personal use, Composio-managed OAuth apps simplify the initial connection. Developers can supply their own OAuth applications or API keys, and Composio also supports self-managed credentials.
The platform can present a connection flow to an application's end users. That lets a product connect each user's own accounts rather than running everyone's requests through the developer's personal login.
Multi-step execution
Composio supports parallel tool execution and a remote runtime for Python and shell work. An agent can collect results, process them and use the output in later actions without carrying every intermediate response through the conversation.
That is useful for tasks such as gathering records from several apps and turning them into a report. The runtime supports the work between calls, while the agent determines what to do with the results.
Triggers provide the other direction: events from connected apps can be delivered to a webhook so an application can respond when something happens. Developers can use that to start a workflow from an app event rather than waiting for a user to type a request.
Custom tools and API access
You can add custom tools and MCP servers alongside the existing catalog. When a predefined tool does not cover a particular endpoint or request option, proxy execution provides authenticated API access within the connected service.
This is particularly useful for developers who need broader API coverage while keeping connection management in one place. The account still needs the permissions required by that endpoint, and the developer supplies the correct request format.
Using Composio with Hermes
For a practical check, I used Hermes with Composio to create a branded link in Dub. Hermes checked whether the requested link was available, submitted the new link through Composio's authenticated API proxy, then fetched the saved record to confirm its destination. A separate redirect check confirmed that the link opened the intended website.
That is the kind of work I want app integrations to handle: a specific request that ends with a usable result in another service. The agent could inspect the response and continue working without needing me to copy information into the Dub dashboard.
The connection was already authorized. This check covered execution through an existing account, rather than first-time onboarding. It also showed why the proxy option is useful: Hermes could use Dub's API directly through Composio when that was the appropriate route.
Where it fits in everyday work
A useful first workflow is a request with a clear output. For a project update, that might mean collecting relevant GitHub issues and preparing a summary for Slack. For sales work, it could mean finding a CRM record and drafting a follow-up using the information in that account.
Those workflows need more than the app's name in a catalog. The available actions must cover the records you need, and the connected account must have access to them. I would choose Composio around the work I want done, then check the relevant tools, rather than connect every available app on day one.
For a recurring process, decide what starts it. A request in a conversation starts with you; an app event can arrive through a trigger; a scheduled agent needs its own running scheduler. Composio supplies app access and event delivery, while your agent or application runs the wider workflow.
Composio vs Alternatives
Composio vs Executor
Executor is worth comparing if you switch between agents and want the same app connections available everywhere. It brings MCP servers, OpenAPI specifications and GraphQL APIs into one catalog, with shared authentication and per-tool rules for allowing, approving or blocking actions.
The agent gets one execute tool and uses TypeScript to discover and call the tools inside it. Several API calls can run within one execution. That makes it useful for connecting a collection of services without loading every tool definition into the model's prompt.
Executor is open source under the MIT license. You can use its hosted Cloud service, run the desktop app or CLI locally, or self-host it. Cloud is free for up to three members, with unlimited integrations and 100,000 executions per month. Team costs $15 per member per month, includes unlimited executions and has a 14-day free trial. Running the software yourself is free; hosting and connected-service costs remain yours.
An Executor execution is one call from the agent to its execute tool, which can make several calls to connected services. Composio meters individual tool executions. For workflows that batch several actions together, that billing unit matters more than comparing the two free-plan totals alone.
I'd choose Executor for a shared gateway around existing MCP servers and APIs, especially when local operation or self-hosting is a priority. I'd choose Composio when its managed app catalog, native agent plugins and end-user connection flows match the work I want to build. Both support tool discovery and code-based execution; Executor's appeal is the reusable gateway and deployment choice, rather than exclusive access to those capabilities.
Composio vs Zapier MCP
Zapier MCP is the comparison I'd make first for a nontechnical team. It advertises more than 9,000 apps and lets you configure the actions an AI client can use. Its MCP calls draw from the same task pool as your Zaps, so existing automation usage matters when choosing a plan.
Zapier's Free plan includes 100 tasks per month. Professional starts at $19.99 per month billed annually with 750 tasks at the entry tier. MCP uses two tasks per tool call.
Composio vs Pipedream Connect
Pipedream Connect is more directly comparable to Composio's developer platform. It provides managed authentication, SDKs, MCP and API access for products that connect their users' accounts.
Pipedream's Startup plan costs $99 per month billed annually or $150 billed monthly. It includes 100 external users and 10,000 usage credits, with additional users and credits billed separately. Its free development environment is for testing, while connecting real external users requires production access.
Pipedream counts a person with several connected accounts as one external user. Its execution meter uses a credit per 30 seconds of compute, with additional users priced at $2 and additional credits at $0.012. That makes the size of your user base and the work each call performs relevant to the comparison.
I'd lean toward Composio for managed app integrations, Executor for a shared MCP/API gateway, Zapier MCP for an existing Zapier setup, and Pipedream Connect when embedded integrations are part of the software you are building.
Composio Pricing
Composio offers Hobby, Pro and Enterprise plans.
Hobby requires no credit card. Usage pauses when an applicable cap is reached. Pro continues with metered usage, and its $29 credit resets each billing month without rollover.
Calls, triggers and connected accounts
With your own OAuth app, API key or MCP credentials, the included monthly allowance is 100,000 tool calls and 50,000 delivered trigger events. Additional paid usage costs $0.0003 per tool call and $0.003 per delivered event.
Composio-managed OAuth apps include up to 20,000 tool calls and 10,000 delivered trigger events within those totals. Paid rates are $0.0005 per tool call and $0.005 per delivered event. They include 1,000 connected accounts, with additional connections priced at $0.10 each on paid usage.
Connections using your own app, API key or MCP are unlimited and free. Tool-search meta-tools and session creation are free, and trigger usage is counted when an event is delivered rather than each time an app is polled.
Execution features and other usage
Some execution features have their own free allowances and additional rates. Proxy execution includes 1,000 calls per month, then adds $0.0002 per call. Direct execution outside a Session and sandbox execution each include 10,000 calls, then add $0.0001 per call when used.
Premium tools using Composio's credentials for paid providers are billed at provider cost plus a 5% platform fee. Using your own provider credentials leaves that provider's bill with you. Your AI assistant or model subscription is also separate from Composio's plan.
For individual use, I'd begin with Hobby and the apps you need. Pro makes sense when you need more usage, additional team members or its spend controls. Developers should choose their credential setup and execution method before estimating production costs.
These rates apply to signups from August 15, 2026. Earlier customers keep their previous plan through December 31, 2026; premium-tool billing applies to all customers from September 10, 2026.
Verdict
I'd shortlist Composio when you want an AI assistant to work across your existing apps. Managed connections and on-demand tool discovery make it useful for personal agents, while the SDKs and end-user authentication give developers a path to building those integrations into a product.
Choose Executor instead if your priority is bringing existing MCP servers and APIs into one gateway that you can share across agents or run yourself. Its free Cloud plan also gives small teams a hosted starting point.
Start with a workflow you already do manually and the accounts it needs. If your assistant's native connections already handle that work, you may not need another service. If app access is what is holding the workflow back, Composio's free plan is a practical place to start.
Connect your first apps with Composio.
