Google Drive MCP Server vs Postgres MCP Pro

A side-by-side look at pricing, capabilities, pros, cons, and our editorial scores.

	Google Drive MCP Server MCP Servers	Postgres MCP Pro MCP Servers
Tagline	Read, list, and search your Google Drive from any MCP-compatible AI client.	Open-source Postgres MCP server with deterministic health checks, index tuning, and safe SQL execution.
Category	MCP Servers	MCP Servers
Pricing	Free· Free and open-source (MIT). Google Cloud/Drive API usage governed by Google's free quotas.	Free· Free and open source (MIT license). No paid tiers.
Model	—	Model-agnostic (works with any MCP-capable LLM); optional OpenAI models for experimental LLM-based index tuning

Use cases	Ground Claude in a folder of meeting notesPull the latest spec doc into a coding agentSummarise a Google Sheet without downloadingSearch Drive from Claude DesktopFetch Docs as Markdown into a RAG pipelineMulti-server MCP setup with GitHub and SlackExtract Slides content as plain text for briefingsReference implementation for a custom Drive MCP fork	AI-assisted query optimization in Cursor or Claude DesktopAutomated index recommendations for slow workloadsEXPLAIN plan review with hypothetical indexesProduction database health monitoring via LLM chatDetecting bloated, duplicate, or unused indexesVacuum and transaction-id wraparound risk auditsSafe read-only SQL exploration by AI agentsSchema introspection for LLM SQL generationShared team Postgres MCP endpoint over SSE
Pros	Official reference implementation - clean, minimal code that's easy to audit or fork. Auto-converts Google Docs, Sheets, Slides, and Drawings to LLM-friendly formats out of the box. Works with any MCP client (Claude Desktop, Cursor, VS Code, Continue, custom agents). Three install paths: npx, Docker, and one-click VS Code - no build step required for most users. MIT-licensed and open source, so you can fork and extend it freely. Standard OAuth 2.0 with local credential storage - no third-party broker in the loop.	Deterministic index tuning based on the Anytime Algorithm plus hypopg what-if simulation, not LLM guesswork Comprehensive PgHero-derived health checks covering bloat, cache, connections, vacuum, replication, and sequences Restricted mode enforces read-only transactions and blocks COMMIT/ROLLBACK escapes via pglast SQL parsing Works with any MCP client (Claude Desktop, Cursor, Windsurf, Cline, Goose, Qodo Gen) and supports both stdio and SSE transports MIT-licensed and free; installs via Docker, pipx, uvx, or uv with clear per-client config recipes Cost-benefit index selection along the Pareto front with configurable performance-vs-storage threshold Actively maintained by Crystal DBA with Discord community and public roadmap on GitHub
Cons	Archived on 29 May 2025 - no upstream maintenance, security fixes, or new features from Anthropic. Read-only: no create, edit, move, share, or delete operations on Drive files. OAuth setup is fiddly - you have to stand up a Google Cloud project and consent screen yourself. Search returns only names and MIME types, not snippets or ranked relevance. No native folder-scoping, permission filtering, or workspace-account controls beyond what the OAuth token grants.	Postgres-only; no MySQL, SQL Server, or other database support Full-featured tuning requires pg_stat_statements and hypopg extensions, which self-managed installs may need to install manually Only two coarse access modes (unrestricted vs restricted) with no per-table or column-level ACLs Credentials are supplied at startup via DATABASE_URI, so switching databases means restarting the server Experimental LLM-based index tuning requires an OpenAI API key and adds external cost/latency Workload compression is basic (query normalization, equal weighting), which can misrank importance in complex workloads
