See setup guidance ↓Original source ↗ SOURCE REVIEW Reviewed 2026-09-21 Evidence 8 linked sources Publisher PSU3D0 Licence Apache-2.0 ↗ Revision 9cc6c5032184 Read what was—and wasn’t—checked ↓ “agent-spreadsheet is the tool interaction service for agent-based spreadsheet usage.” PSU3D0 · upstream description ↗ Our analysis follows below. 01 / THE REASONING ## Why this made the selection. - Exposes structured workbook operations and revision-aware workflows instead of relying entirely on screen automation. - Documents the differences between workbook formats, read-only containers and write/recalculation-enabled builds. ### A good fit for - Inspecting or editing workbooks inside a deliberately chosen working directory. ### Weigh up before choosing - HTTP has no built-in authentication and binds to loopback by default; keep it local or add an appropriate access layer. - Recalculation uses available native/LibreOffice backends and is not a claim of complete Excel compatibility. - Legacy workbook formats have more limited, read-oriented support. 02 / THE REVIEW RECORD ## What we actually inspected. Source review has boundaries. A clear record is more useful than a “safe” badge. ### Material inspected - README.md (installation, capability and permission sections) - Cargo.toml - crates/agent-spreadsheet-mcp/Cargo.toml - crates/agent-spreadsheet-mcp/src/main.rs - crates/agent-spreadsheet-mcp/src/server.rs - LICENSE - crates/agent-spreadsheet-mcp/src/lib.rs ### Our findings - The current product/package is agent-spreadsheet-mcp; spreadsheet-mcp is the older repository name. - The manifest and MCP entrypoint are Rust; the README documents explicit stdio mode and an HTTP default. - Workspace, enabled-tool and recalculation settings determine the exposed surface; a slim container and a full build are not equivalent. ### Not established by this review - Server startup, authentication and tool execution were not tested. The review applies to the material and revision named here. A newer upstream release can change its behavior. 03 / PUT IT TO WORK ## Connect a server deliberately. Upstream setup instructions ↗ DOCUMENTED COMMAND cargo install agent-spreadsheet-mcp Copy command ↗ Copying does not execute this command. It may retrieve a newer version than the reviewed source. - Install the MCP package, then configure an explicit workbook workspace root. - Use the documented stdio configuration for a local client and enable write/recalculation features only when the task needs them. ### Before you start - A Rust toolchain for the source-build command and access to the intended workbook directory. ### Documented configuration example Use the client and authentication context described in the setup guidance. Configuration formats vary between hosts. { "mcpServers": { "spreadsheet": { "command": "agent-spreadsheet-mcp", "args": [ "--workspace-root", "/path/to/workbooks", "--transport", "stdio" ] } } } Copy configuration ↗ ### Compatibility An MCP client supporting stdio, Streamable HTTP. · A Rust toolchain for the source-build command and access to the intended workbook directory. · Configuration example follows the documented local mcpServers form; replace the example workspace path. ### Implementation Rust ### Transports stdio · Streamable HTTP ### Spreadsheet automation / Configured credentials or local access - Reads workbook files; enabled edit/lifecycle tools write workbook state and output files. - Recalculation or screenshot capabilities can invoke the configured backend. ### Cost model Local compute/storage and any required spreadsheet backend apply. 04 / FOLLOW THE EVIDENCE ## The source trail.
