Best Elixir MCP Servers
Elixir is a dynamic, functional programming language designed for building scalable and maintainable applications. It leverages the Erlang VM, known for running low-latency, distributed and fault-tolerant systems.
Why this server?
Indexes Elixir codebases to provide symbol search, call graph navigation, and change impact analysis.
AlicenseAqualityAmaintenanceEnables read-only querying of a local repository through a deterministic tree-sitter symbol and edge graph, exposing keyword search with exact file:line hits, regex text search, per-file symbol skeletons, caller/callee traversal, and directory-level maps of clusters, hubs, and hotspots over stdio.10269 npm1Apache 2.0Why this server?
Queries Hex.pm for the latest version of Elixir packages.
AlicenseAqualityCmaintenanceAn MCP server that queries 19 package registries (npm, PyPI, crates.io, etc.) to retrieve the latest version of packages and their metadata.2123 PyPI1MITWhy this server?
Scans Elixir codebases for quantum-vulnerable asymmetric cryptography, returning findings and a readiness score.
AlicenseAqualityAmaintenancePost-quantum readiness for AI coding agents: scans code for quantum-vulnerable cryptography (RSA/ECDH/ECDSA/DH) and returns NIST ML-KEM/ML-DSA/SLH-DSA (and hybrid) migration guidance, with fix verification and dependency checks. Content-based, advisory tools only; runs local (npx @quantakrypto/mcp) or as a hosted OAuth endpoint.1615Apache 2.0Why this server?
Audits Elixir applications, including Mix project structure, task ownership, and ExUnit test detection.
AlicenseAqualityAmaintenanceocal-first, read-only MCP server that audits repository test architecture across ten language ecosystems. It returns deterministic evidence-backed findings, blockers, rankings, and repository-native test plans without modifying source files.19658 npmMITWhy this server?
Generates repository maps for Elixir codebases, highlighting key files and code structures
AlicenseAqualityDmaintenanceA powerful tool designed to help, primarily LLMs, understand and navigate complex codebases. It functions both as a command-line application for on-demand analysis and as an MCP (Model Context Protocol) server, providing continuous repository mapping capabilities to other applications.

Supports execution of Elixir code snippets with result display
AlicenseBqualityFmaintenanceMCP Server for running code snippet and show the result.11,517 npm242MITWhy this server?
Provides AST-aware code intelligence for Elixir 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.147MITWhy this server?
Allows debugging Elixir applications through the Elixir LS debugger, including breakpoints and debug inspection capabilities.
AlicenseAqualityBmaintenanceEnables any MCP client to debug programs through the Debug Adapter Protocol, supporting launch/attach, breakpoints, stepping, variable inspection, evaluation, and memory operations via a single debug tool.113 npmMITWhy this server?
Provides integration with Scenic (an Elixir UI framework), enabling AI-driven automation and testing for Scenic applications through a TCP server that exposes app state and allows interaction with UI elements.
AlicenseAqualityDmaintenanceA Model Context Protocol server that enables AI-driven automation and testing of Scenic Elixir applications through a TCP connection.68MIT
