A Composio alternative for Google Sheets MCP

Composio connects hundreds of apps to your agent with read-write access and OAuth. PasteSheet does one narrow thing: it publishes a single Google Sheet as a read-only MCP server and REST API, from a pasted URL, with nothing to authorize.

Key facts

  • Google's API requires a Google Cloud project plus OAuth credentials or a service account before it will return a single row. source
  • It needs no Google Cloud project, no OAuth consent screen and no service-account JSON. You paste a share URL, and MCP is included on the Free plan.
  • The split is publish versus connect: an integration platform wires your Google account to your agent, while a published endpoint is readable by anyone's app, site or agent.
  • PasteSheet's MCP server exposes three tools — list_tabs, get_schema and query_rows — and is read-only by design: an agent can query your sheet but can never modify it.

What Composio does

Composio is an integration platform that gives AI agents access to 500+ apps — Google Sheets among them — through MCP and direct APIs, with OAuth handling, RBAC, and dozens of read-write tools per app. It is powerful and developer-oriented: you connect your Google account so your agent can act across your stack.

That breadth is the point, and the cost. For "I just want this one sheet readable by an agent," it is a lot of surface area, a Google account connection, and a read-write default you may not want.

Where PasteSheet is different

PasteSheet is not an app hub — it publishes one sheet as a data source:

  • No account to connect: paste a share URL. There is no Google Cloud project, OAuth consent screen, or service account to configure.
  • Publish, don't connect: the endpoint is readable by anyone's app, site, or agent — not just your own assistant wired to your account.
  • Read-only by design: the MCP tools (list_tabs, get_schema, query_rows) can never modify the sheet — no prompt injection can delete a row.
  • Typed query engine: filter, search, sort, and aggregate through one query_rows tool, instead of many cell/range operations.

Which one you actually want

If you are building an agent that automates read-write workflows across many apps, Composio (or Zapier) is the right tool. If you want to publish a spreadsheet as a safe, read-only data source that any app or agent can query, PasteSheet is purpose-built for it.

What it costs

MCP is included on the Free plan. Connect any public endpoint over MCP with no Google Cloud project and no credit card. Private endpoints and the account-wide workspace server need a paid plan (from Starter ($9/mo)) for the keys and OAuth they authenticate with.

Pro adds full-text search and aggregation (count, sum, avg, group_by) that your AI agent can call through query_rows.

Frequently asked questions

Is PasteSheet a good Composio alternative?

For Google Sheets specifically, yes. PasteSheet publishes one sheet as a read-only MCP server and REST API with no OAuth or Google Cloud setup. Composio is a broad, read-write, multi-app integration platform.

Do I connect my Google account like I do with Composio?

No. PasteSheet reads a sheet shared with "Anyone with the link" from a pasted URL. There is no OAuth flow or account connection to authorize.

Can PasteSheet automate across other apps like Composio?

No — that is Composio's strength. PasteSheet is focused on publishing a sheet as a read-only data source, not orchestrating read-write workflows across hundreds of apps.
