TaglineArchived MCP server that lets Claude and MCP clients generate images via EverArt's FLUX, SD 3.5 and Recraft models.Open-source Postgres MCP server with deterministic health checks, index tuning, and safe SQL execution.
CategoryMCP ServersMCP Servers
PricingFree· MCP server is free and open source; requires an EverArt account and API key (EverArt itself is a paid image-generation service with credit-based pricing).Free· Free and open source (MIT license). No paid tiers.
ModelFLUX 1.1, FLUX 1.1 Ultra, Stable Diffusion 3.5, Recraft (Real and Vector) via EverArtModel-agnostic (works with any MCP-capable LLM); optional OpenAI models for experimental LLM-based index tuning

Use cases
In-chat image generation from Claude DesktopIDE-driven mockup and illustration generation in VS CodePrompt-to-image reference art for design brainstormingAgent-invoked cover art and thumbnail generationReference implementation for building custom image-API MCP serversQuick FLUX 1.1 Ultra renders inside an LLM workflow
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
  • Drop-in MCP server that lets Claude Desktop or VS Code generate images through natural-language tool calls
  • Exposes five current image models (FLUX 1.1, FLUX 1.1 Ultra, SD 3.5, Recraft Real, Recraft Vector) through a single tool
  • Tiny TypeScript codebase makes it a useful reference for building your own image-API MCP wrapper
  • Installs via npx or Docker with a one-click VS Code button, so setup is a few minutes
  • Open source under the MCP servers repo license, easy to fork and extend
  • 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
  • Officially archived in May 2025 and no longer maintained upstream
  • Only one tool (generate_image) with no editing, variation, upscaling or img2img workflows
  • Fixed 1024x1024 output, no aspect-ratio or resolution controls
  • Requires a paid EverArt account and API key; image generation is not free
  • No prompts or resources exposed, so richer agentic patterns need custom code
  • 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
