Secure Google Sheets MCP Server

PortEden's server exposes all 13 Google Sheets tools, from range reads and searches to writes, appends, and new spreadsheet creation. What makes it different from a generic Google Sheets MCP is the data firewall in front of those tools: PortEden inspects every tool-call request, applies your access policy, and redacts sensitive cell values in the response before the agent ever sees them.

The result is secure Google Sheets access for AI agents. You decide whether a client gets read-only or read-write access, scope it to a single spreadsheet or range, mask sensitive columns, and review every call in an audit log. OAuth handles authentication, so there is no static key to leak.

Every tool can be allowed or denied per client. Access levels are enforced at the firewall on each call.

Available on Claude Pro, Team, and Enterprise. The same flow works for Claude Cowork.

Decide exactly what each AI client can do with Sheets. Allow reads but deny writes, or scope a connection to a single spreadsheet or even a named range, so an agent that asks for everything only ever receives what policy allows.

PortEden runs a redaction pass on every tool response before it leaves the firewall. Sensitive cell values are replaced with stable placeholders, so the agent can reason over the data without the raw values entering the model's context.

Every Google Sheets tool call is recorded: which client, which user, which tool, the arguments passed, the policy decision, and the redacted response. Export it or stream it to your SIEM for review.

Bind each MCP connection to a user or role with a scoped, revocable token. Group policies by team so a new hire inherits the right Sheets access on day one, and revocation is instant and server-side.

How do I connect Claude to Google Sheets using MCP?

That is the whole point of PortEden. The connection uses OAuth, so there is no static key to leak. Every tool call passes through a policy decision, sensitive cell values are redacted before the agent sees them, and every call is written to an audit log. You can scope a client to read-only, to a single spreadsheet, or to specific ranges.

Can I give an AI agent read-only access to Google Sheets?

Yes. Deny the write, append, create, and delete tools in your policy and the agent keeps the five read tools (read, read_tab, read_all, get_metadata, and search). You can also allow writes only on specific spreadsheets or ranges.

Does redaction stop the agent from working with my data?

No. PortEden replaces sensitive values with stable placeholders rather than removing them, so the agent can sort, deduplicate, and summarize by handle. Round-trip writes are de-redacted server-side, so an update aimed at a placeholder still lands on the correct cell. The raw values never enter the model's context.

What Google Sheets tools does the MCP server expose?

Thirteen tools: read, read_tab, read_all, get_metadata, and search for reading; write, append, rename, and add_tab for editing; create and copy for new files; and delete_tab and delete for removal. Each tool can be allowed or denied per client.

Which AI clients work with the Google Sheets MCP server?

Any MCP-compatible client. That includes Claude Desktop, Claude Web, ChatGPT (via Connectors), Cursor, Windsurf, Cline, and Zed. Point the client at the remote URL and authenticate once.

How is this different from connecting Google Sheets directly?

A direct connector or community MCP server usually proxies the Google Sheets API one to one, handing raw cell values to the model with a broad OAuth grant. PortEden sits in between as a data firewall: scoped tokens, per-tool and per-range policy, redaction on every response, and a full audit log. You get the same tools with control over each call.

Does it cost anything to use the Google Sheets MCP server?

There is a free tier that covers 1,000 tool calls per month. Paid plans raise the limit. A tool call is one MCP request, so reading 200 rows is one call, not 200. See the pricing page for current limits.

Scope each AI client to the tools, spreadsheets, and ranges it actually needs.
