Best Haskell MCP Servers
Haskell is a purely functional programming language with strong static typing, type inference, and lazy evaluation. It is designed for teaching, research, and industrial applications.
Why this server?
Provides AST-aware code intelligence for Haskell codebases, including semantic search, dependency graphs, and refactoring analysis.
AlicenseAqualityBmaintenanceStandard coding agents waste 70% of context tokens re-reading raw files with shell grep. Synapse-MCP indexes your codebase into a sub-millisecond local AST graph—giving Claude Code, Cursor, and Windsurf exact caller trees, 60% lower token spend, and zero-hallucination refactoring.2141MITWhy this server?
Enables running Haskell code with sandboxing, resource limits, and output capture; scaffolds a temporary Nix project.
AlicenseAqualityAmaintenanceAn MCP server that lets AI models run code in 31 languages, evaluate symbolic math and logic problems, and measure complexity—exposed as 48 tools for execution, session management, translation, optimization, and more.249232 PyPI3Apache 2.0Why this server?
Provides execution environment for Haskell code snippets with results
AlicenseBqualityFmaintenanceMCP Server for running code snippet and show the result.11,433 npm246MITWhy this server?
Provides dependency tracing and code analysis for Haskell codebases, indexing symbols, function calls, and modules to support impact analysis, test generation, and code understanding.
AlicenseAqualityDmaintenanceMaps function and component dependencies in Haskell and ReScript codebases, providing LLMs with a real dependency graph for accurate test generation and change-impact analysis.1082 npmMITWhy this server?
Provides 40+ static code analysis tools for enterprise-scale Haskell codebases, including module analysis, function call graphs, type system relationships, typeclass analysis, import dependencies, and complexity metrics.
FlicenseBqualityDmaintenanceProvides static code analysis for enterprise-scale Haskell codebases with 40+ comprehensive tools for analyzing modules, functions, types, classes, imports, and architectural dependencies through real-time queries.424-Why this server?
Identifies installed Haskell compiler (ghc) and development tools.
AlicenseNot gradedqualityDmaintenanceAn MCP server that provides detailed information about your development environment to the Cursor code editor, enabling more context-aware assistance.7MITWhy this server?
Provides specialized prompts for Haskell development, including typed-hole exploration guidance when working with the Haskell Language Server.
AlicenseNot gradedqualityFmaintenanceBridges Large Language Models with Language Server Protocol interfaces, allowing LLMs to access LSP's hover information, completions, diagnostics, and code actions for improved code suggestions.1,077 npm124MITWhy this server?
Adds Haskell code analysis capabilities, including call graph mapping and liveness tracking.
Why this server?
Haskell is recognized by file discovery and the default LSP registry, letting Lore snapshot and structurally enrich Haskell sources through the Haskell language server.
AlicenseNot gradedqualityBmaintenanceEnables LLM agents to query a codebase's structural knowledge (symbols, imports, call graphs, etc.) via MCP, reducing tokens and improving correctness compared to raw file access.35 npm7MIT
