Ac MCP Server

Most AI and media services work still happens through a UI a human drives. Ac MCP MCP server moves it into the conversation instead. A Model Context Protocol (MCP) server that exposes the APLCart idiom collection with semantic search capabilities. APLCart is a searchable collection of APL expressions with descriptions.

The short version

APLCart is a searchable collection of APL idioms and expressions maintained at https://aplcart.info/

• Find APL expressions by exact syntax match
• Search across syntax, descriptions, and keywords
• Get keywords for specific APL expressions
• Natural language queries using OpenAI embeddings

The tools it exposes

The server publishes 5 tools. What each one is for:

• lookup-syntax — Exact match on APL syntax
• search — Substring search across syntax, description, and keywords
• keywords-for — Get keywords for a specific syntax
• semantic-search — Natural language search using embeddings
• Prerequisites — The Prerequisites tool exposed by this server

Getting it running

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

What it needs from you

Configuration is passed through the environment: APLCART_USE_DB, OPENAI_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

• Python 3.11 or higher - OpenAI API key (for semantic search functionality)

How it compares

Plenty of AI and media services servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Ac MCP's toolset — lookup-syntax, search, keywords-for and 2 more — is a fair guide to whether it matches your workflow. It is maintained by xpqz; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Things to watch

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
