excel-mcp-server
A server-deployed MCP (Model Context Protocol) server that exposes Excel-related operations (upload, read, generate from 2D arrays, download link, and edit operations like add row/column and modify cell) over an SSE-based endpoint. Configuration is done via YAML (port, SSE endpoints, capabilities, and Excel storage/download settings).
Score Breakdown
⚙ Agent Friendliness
🔒 Security
From the provided README, authentication/authorization and rate limiting are not documented. TLS/HTTPS requirements are not stated (SSE is configured but transport security is unclear). Excel files are stored temporarily on the server filesystem via a configured savePath; without documented cleanup/access controls, there is potential for data leakage or accumulation. Dependency hygiene cannot be verified from the provided information.
⚡ Reliability
Use Cases
- • LLM/agent workflows that need to create or transform Excel files programmatically
- • Uploading spreadsheets for analysis or extraction into structured data
- • Generating new Excel files from tabular/2D-array inputs
- • Applying spreadsheet edits (add rows/columns, update specific cells) and returning download URLs
Not For
- • High-security multi-tenant environments without documented authentication/authorization
- • Use cases requiring strict auditability/compliance guarantees not covered in the provided docs
- • Production environments where SSE scaling, backpressure, and file lifecycle/cleanup policies are unknown
Interface
Authentication
No authentication method, API key, or authorization configuration is described in the provided README content.

Agent Metadata
Known Gotchas
- ⚠ No documented auth/tenant isolation: agents may be able to invoke tools as soon as the service is reachable.
- ⚠ Excel file storage path is configured as a local temp location; lifecycle/cleanup and concurrency behavior are not documented.
- ⚠ Idempotency for operations like upload/add row/add column/modify cell is not stated; retries could create duplicates or repeated edits.
- ⚠ SSE endpoint configuration suggests an SSE transport; any tool-response streaming semantics and timeouts are not documented.
