Docsmith MCP
Enables processing of Excel, Word, and PDF documents through reading, writing, and metadata extraction. It leverages a secure Pyodide WebAssembly environment to handle document parsing with support for paginated results.

Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
When Vitest UI server is listening, arbitrary file can be read and executed
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
PostCSS: Arbitrary file read and information disclosure via attacker-controlled sourceMappingURL in CSS comments

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
4/4 tools missing one or more hints — read_document (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); write_document (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_document_info (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +1 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
No arbitrary install scripts
Has postinstall/preinstall script — runs arbitrary code on npm install
Remove postinstall/preinstall hooks unless they’re essential.
Production dependencies are patched
0 critical, 1 high severity in production deps — @modelcontextprotocol/sdk@1.25.3 (high), zod@3 (low)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
5 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
