Composio vs Zapier MCP: what is the real difference?
Composio vs Zapier MCP comes down to what each product extends. Composio extends an agent platform with a gateway that companies can put in front of their staff. Zapier MCP extends a person's Zapier account into their AI client. The two differ on the billing unit, on who holds the app credentials, and on what one person's access looks like.
An IT lead is asked to let sales, support and finance use Claude and ChatGPT with the company's apps. Two names come up first. MCP (Model Context Protocol) is the standard way an AI assistant calls tools in other apps. Both Composio and Zapier MCP speak it, so the question is how each one fits a company rollout, and where a different design fits.
| Question | Composio | Zapier MCP | Elaichi |
|---|---|---|---|
| Built for | Developers building agents, and people connecting Claude or ChatGPT to their apps (composio.dev) | People who already automate in Zapier (help article) | A company giving its own staff governed access |
| Apps | "1,500+ apps available" (MCP Gateway) | 9,000+ apps and 40,000+ actions (help article) | 600+ connectors, plus a team's own remote MCP server |
| Address | A gateway endpoint plus one per team (MCP Gateway) | One shared endpoint, usually one server per person per client (connections) | One address, https://api.elaichi.ai/mcp, the same for every organization; one grant per person per client |
| App credentials | AES-256 encrypted, decrypted in Composio's execution layer (Enterprise) | Zapier holds them (connections) | A separate credential service holds them, encrypted |
| Access rules | Per user and per role, down to one action (Enterprise) | App and action restrictions, account-wide (security) | Restrictions per role or per member, down to one tool |
| Record of calls | User, team, tool, action and outcome, denied calls included (Enterprise) | History tab per user, plus the account audit log (security) | One entry per call that reaches execution, succeeded or failed; a call refused earlier writes no row |
| Billing unit | Tool calls; Pro is $29 a month (pricing) | Two tasks per successful call, from the plan (usage) | Seats; Gold lists at $15 per user per month in USD (pricing) |

What are Composio and Zapier MCP each built for?
Composio is built first for people who build agents, and Zapier MCP is built for people who already work in Zapier. Composio's homepage speaks to two audiences. One wants Claude or ChatGPT to act in their apps; the other builds agents on the Composio Platform (composio.dev, checked October 2026).
Composio Connect is a shared MCP URL, connect.composio.dev/mcp, that reaches its apps through 7 meta-tools. When an agent first needs an app, the person approves an OAuth link in the browser (Composio Connect docs, checked October 2026). The company-facing piece is the MCP Gateway. The gateway has an endpoint of its own, and each team gets one scoped to the tools it may use. SSO (one company login for every app) verifies the user before any tool resolves (Composio MCP Gateway, checked October 2026).
Zapier's help article describes Zapier MCP as the link between a person's MCP client and their Zapier account. Its tools run on the same app connections and actions that the person's Zaps use (What is Zapier MCP, checked October 2026). Zapier's own comparison page frames the split the same way. It calls Zapier a "no-code AI orchestration platform" and Composio a "developer-first integration and authentication layer" (Zapier vs. Composio, checked October 2026).
How do Composio and Zapier MCP charge for usage?
Composio charges for tool calls, and Zapier MCP spends tasks from a Zapier plan. Composio's pricing page counts each tool execution once and leaves meta tools such as tool search free. Trigger events, premium tools and usage-based add-ons are billed as well (Composio pricing, checked October 2026).
The same Composio page lists three plans (checked October 2026):
- Hobby: $0, with 100,000 tool calls, 50,000 triggers and 3 team members a month (pricing).
- Pro: $29 a month, with a $29 usage credit that expires at the end of each billing month, and unlimited team members (pricing).
- Enterprise: custom terms. SSO, SCIM and customer-managed keys sit here, not on Hobby or Pro (pricing).
Zapier MCP has no separate MCP bill. It runs on the person's existing Zapier plan, and each successful tool call uses two tasks at a fixed rate. Failed calls use none (Zapier MCP usage and billing, checked October 2026). A call that finds a HubSpot contact and a second call that emails them through Gmail use four tasks between them.
Both bills move with how much the AI does. Elaichi's bill moves with headcount instead, and the trade-offs of each meter are set out in the per-seat and per-call pricing breakdown.
Who keeps the app credentials in Composio and Zapier MCP?
In both products the vendor keeps the app credentials, so the AI client never holds a third-party API key. Zapier says it holds the app credentials for Zapier MCP. On the OAuth path, the MCP client stores and refreshes its own OAuth token (how Zapier MCP connections work, checked October 2026).
The case to watch in Zapier MCP is the connection token. A client off Zapier's supported list, or a person's own code, connects with one instead. Zapier describes it as long-lived and bound to one server, and anyone holding it can run that server's tools. Zapier's docs say to treat it like a password (Zapier connections page, checked October 2026).
Composio's Enterprise page says credentials are stored AES-256 encrypted and decrypted inside Composio's execution layer. Developers do not handle raw credentials, and the model does not see them (composio.dev/enterprise, checked October 2026). A deeper read is in the Composio security review.
Elaichi keeps app credentials in a separate credential service, encrypted at rest with AES-256-GCM. It fetches them into memory only for the call that needs them. The MCP address carries no credential, and the AI client holds only an Elaichi token, sent in a header.
How does each person get access in Composio and Zapier MCP?
Zapier MCP gives each person their own servers, while Composio's gateway gives each team its own endpoint alongside the gateway's own. In Zapier MCP every client uses the same endpoint. Each person owns their own servers on the Zapier account, usually one per named MCP client (Zapier connections, checked October 2026).
An organization rollout lets an admin make Zapier available in the MCP client. Each member still signs in to Zapier and runs tool calls as themselves (Zapier MCP rollout, checked October 2026). Sharing a server with teammates needs a Team or Enterprise plan. It lets them review or manage its tools, not run them as the owner (Zapier server access, checked October 2026).
What happens to a member's servers when they leave is not documented on Zapier's MCP security, server access or usage pages (checked October 2026). Put that question to Zapier before a rollout.
Composio's MCP Gateway page lists SAML or OIDC single sign-on and SCIM 2.0 (automatic user provisioning from a directory). SCIM maps directory groups to teams and revokes access at offboarding (Composio MCP Gateway, checked October 2026). Composio's pricing page lists shared connection tool calls as a metered add-on. In those, other users reuse one connected account (Composio pricing, checked October 2026).
What can an admin restrict and review in each one?
Composio documents permissions per user and per role, and Zapier MCP inherits Zapier's account-wide restrictions. Composio's Enterprise page says admins set permissions down to a single action. The rules are checked in the request path, before the model is involved. Each call is logged with the user, team, tool, action and outcome, including calls that policy denied (composio.dev/enterprise, checked October 2026).
The Composio gateway adds two details. Members can ask for tools they cannot reach, and admins approve or deny centrally. Tool-call payloads are not stored, and audit records hold metadata, kept for 7 days to 1 year (Composio MCP Gateway, checked October 2026). Elaichi's audit log has one limit to compare: it writes a row for each call that reaches execution, succeeded or failed, and a call refused before that point, for example for a tool a restriction withholds, writes no row.
Zapier MCP enforces app and action restrictions set at the Zapier account level. Those restrictions cannot be set for Zapier MCP alone; they apply across every Zapier feature. With Zapier Workspaces, admins can allow or restrict Zapier MCP for specific users and set task quotas per workspace. The History tab shows tool calls per user, and superadmins can review any user's. MCP events also reach the account audit log (Zapier MCP security, checked October 2026).
What is the third option for a company-wide rollout?
The third option is a governed MCP control plane: one hosted MCP gateway that every employee's AI client signs in to. Elaichi is built that way. Every person connects Claude, ChatGPT, Cursor or any MCP client to one address, https://api.elaichi.ai/mcp. They sign in over OAuth, the standard flow that hands a client a token instead of a password. Each person approves their own grant, the record that ties one client to one person. Every call then acts as that person.
Elaichi serves 600+ connectors. It authors and runs most of them itself. The rest are native MCP connectors, where the app's vendor builds and runs its own MCP server and Elaichi handles sign-in, access and audit. A team on Gold can also add its own remote MCP server under the same rules. In Elaichi, connected tools are never listed one by one, however few there are. The model finds a tool with search_tools and runs it with execute_tool.
Admins restrict whole connectors or single tools for a role or for one member, and a block always beats an allow. A role or restriction change takes effect within about two minutes. In Elaichi, removing or suspending a member revokes every live grant in the same transaction as the membership change, so a removed or suspended member's clients stop on their next call. A member who needs a restricted tool can file an access request from the client, and an admin decides it in the console.
Every call that reaches execution writes one audit row, succeeded or failed. A call refused earlier, for example for a tool a restriction withholds, writes no row. Everyone can see their own activity in the audit log. People with the audit permission see the whole organization, and the read-only Auditor role does not take a billable seat. Gold lists at $15 per user per month in USD, or $10 billed annually. The pricing page lists SAML or OIDC SSO and SCIM on Gold. Gold starts with a 14-day trial and needs no card to begin.
When is Composio or Zapier MCP the right answer?
Composio fits when seats do not map to your employees, for example when the tool users are your own customers. Zapier MCP fits when your team already runs on Zapier. Composio's Enterprise page says it maps an agent and its end user to a connected account. That account may belong to an employee or to the customer's own customer (composio.dev/enterprise, checked October 2026). That fits a product team putting tool access inside something it sells.
Choose Composio when:
- You are building an agent into your own product, and seats do not map to employees.
- You need an app that Composio lists and the Elaichi catalog lacks.
- You want a separate endpoint per team, or self-hosting, which Composio's Enterprise page offers (composio.dev/enterprise, checked October 2026).
Choose Zapier MCP when:
- Your team already builds Zaps, and the apps it needs are already connected in Zapier.
- Each person signs in to Zapier themselves, and Zapier's restrictions and History answer your reviewer.
- Your task allowance absorbs two tasks per successful call at the volume you expect.
Elaichi assumes a workforce. Roles, seats and SCIM describe employees and contractors, not your end users. It has no per-team endpoint. Every new grant needs a person to approve a consent screen, so it does not suit an agent that runs unattended in a build pipeline. Three people with one read-only app may need nothing at all, as the post on skipping a gateway for now argues.
Which one should a company pick?
Pick by who uses the tools and who has to answer for them. Three questions sort most cases in one meeting:
- Who holds the sessions? Your customers point to Composio. Your employees point to Composio's gateway, Zapier MCP or Elaichi.
- Where are the apps connected now? If they are already connected in Zapier, Zapier MCP reuses that work. If not, check your five most-used apps against the connector catalog and both vendors' lists.
- Who answers the security reviewer? One admin may have to say what a role can reach, cut off a leaver and show each call that ran. Test exactly that in a pilot on each product.
Each pairing has a fuller head-to-head. The connector authorship and endpoint questions are in Elaichi compared with Composio. The per-member server model is in the Zapier MCP alternative guide. For the category itself, start with what an MCP gateway does.
