# 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. *Last updated: 2026-07-11 · Source: * ## 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](https://developers.google.com/workspace/sheets/api/guides/authorizing)) - 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](https://pastesheet.com/guides/google-sheets-mcp-vs-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. New to this?

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`. **Starter — $9/month.** For indie makers shipping a real app. - Endpoints: 10 - Requests: 50,000 / month - Rows per endpoint: 5,000 - Tabs per endpoint: 5 - Rate limit: 300 / minute ## 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. ## Sources - [Authorize requests — Google Sheets API](https://developers.google.com/workspace/sheets/api/guides/authorizing) — Google - [Model Context Protocol specification](https://modelcontextprotocol.io/specification/2025-06-18) — Model Context Protocol ## Related guides - [Self-Hosted Google Sheets MCP Alternative](https://pastesheet.com/guides/self-hosted-google-sheets-mcp-alternative) — A hosted alternative to self-hosted Google Sheets MCP servers: no service account, Docker, or uvx — paste a share URL and get a read-only endpoint. - [Google Sheets MCP vs Zapier & Composio](https://pastesheet.com/guides/google-sheets-mcp-vs-zapier) — Zapier and Composio give Google Sheets MCP for read-write automation.
