MCP server for Moodle plugin development: structural context of a Moodle install for AI agents.

VerifiedSTDIODesktop onlyDeveloper ToolsKnowledge & Memory

Overview

AI-generated overview

Gives an AI assistant structural context about a local Moodle installation and its plugins, so it can answer codebase questions and scaffold plugins.

What it does
build82 scans a Moodle source tree (version.php, db/*.php, XMLDB schemas, PHPDoc, hooks, tasks, capabilities, web services) and writes Markdown context files under .build82/. It exposes 13 MCP tools, 3 prompts and resources to generate context, search the API and plugin indexes, explain a plugin, run an environment doctor, package a plugin for release, and create a plugin skeleton. A file watcher regenerates a dev plugin's context when its sources change, and two PHP extraction backends (regex or tree-sitter) are available.
When to use it
Use it when developing or maintaining Moodle plugins and you want an assistant to understand the real conventions of a specific installation. It suits codebase questions, consistent plugin scaffolding, and keeping generated docs in sync while you work.
Requirements
A local Moodle installation whose source tree build82 can read, plus an MCP client. Distributed as a single static binary (Linux, macOS, Windows) or built from source with Go 1.26+. Optional universal-ctags on PATH for a tags file. The Moodle path is supplied via BUILD82_MOODLE_PATH.
Before you install
It reads and writes inside the Moodle tree, creating .build82/ directories at the Moodle root and each plugin root. It can package a plugin for release and create a new plugin skeleton, so review generated files before committing. The self-update command downloads and replaces the running binary, though downloads are checksum-verified and a backup is kept for rollback. On macOS the binary is not notarized and on Windows it is not code-signed, so first-run warnings must be cleared manually.

Installation

In SourceWeft

  1. Open build82 in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

An MCP (Model Context Protocol) server that gives AI assistants structural understanding of a Moodle installation and its plugins, so they can answer questions about the codebase and build plugins that follow its real conventions. Distributed as a single static binary.

Table of Contents

Overview

Point build82 at a Moodle installation and it scans the codebase (version.php, db/*.php, XMLDB schemas, PHPDoc, hooks, tasks, capabilities, web services...) and generates a set of Markdown context files describing the installation and any plugin you're developing. An AI assistant connected to it can then answer questions about the codebase, scaffold new plugins consistently with existing conventions, and keep the docs in sync as you work.

Main features:

  • 13 global indexes of the installation — API index, DB tables, events, tasks, capabilities, classes, web services, the plugin index and more.
  • 12 per-plugin context files — architecture, dependencies, runtime flow, settings, and an AI-ready summary.
  • 13 MCP tools, 3 MCP prompts and MCP resources — generate context, search the API and plugins, explain a plugin, diagnose the environment (doctor), package a plugin for release, and create a new plugin skeleton.
  • File watcher that regenerates a dev plugin's context whenever its sources change.
  • Two PHP extraction backends — fast regex (default) or pure-Go tree-sitter.
  • Clean output — everything is written under .build82/ (at the Moodle root and at each plugin's root), never loose in the Moodle or plugin root.
  • Native client registration for 8 MCP clients, and a checksum-verified self-update with rollback.

Prerequisites & Quick Installation

Prerequisites:

  • A local Moodle installation (build82 reads its source tree).
  • An MCP client — see Client Setup.
  • Optional: universal-ctags on PATH, to also generate a .build82/tags file for editor navigation.
  • Only to build from source: Go 1.26+.

Download a release binary (no Go toolchain required). Every release ships a checksums.txt — verify it before trusting a downloaded binary. Full step-by-step guide with checksum verification and troubleshooting: Installation Guide.

build82 --version
🍎 macOS

Check your chip with uname -m (arm64 = Apple Silicon, x86_64 = Intel):

bash
# Apple Silicon (M1/M2/M3/M4)curl -LO https://github.com/oito2/mcp-build82/releases/latest/download/build82_darwin_arm64curl -LO https://github.com/oito2/mcp-build82/releases/latest/download/checksums.txtshasum -a 256 -c checksums.txt --ignore-missing \  && chmod +x build82_darwin_arm64 \  && sudo mv build82_darwin_arm64 /usr/local/bin/build82

The binary isn't notarized by Apple, so Gatekeeper will refuse to run it the first time — clear the quarantine flag: xattr -d com.apple.quarantine /usr/local/bin/build82.

🪟 Windows
powershell
Invoke-WebRequest -Uri "https://github.com/oito2/mcp-build82/releases/latest/download/build82_windows_amd64.exe" -OutFile "build82_windows_amd64.exe"Invoke-WebRequest -Uri "https://github.com/oito2/mcp-build82/releases/latest/download/checksums.txt" -OutFile "checksums.txt"Get-FileHash .\build82_windows_amd64.exe -Algorithm SHA256

Compare the printed Hash with the build82_windows_amd64.exe line in checksums.txt; continue only if they match:

powershell
Unblock-File .\build82_windows_amd64.exeNew-Item -ItemType Directory -Force -Path "$env:LOCALAPPDATA\build82"Move-Item -Force .\build82_windows_amd64.exe "$env:LOCALAPPDATA\build82\build82.exe"[Environment]::SetEnvironmentVariable("Path", "$env:Path;$env:LOCALAPPDATA\build82", "User")

Restart your terminal and run build82 --version to confirm it's on your PATH. The binary isn't code-signed; Unblock-File above keeps SmartScreen from blocking the first run ("Windows protected your PC") — if it still appears, click More info → Run anyway.

Or build from source (requires Go 1.26+):

bash
go install github.com/oito2/mcp-build82/cmd/build82@latest

Client Setup

Register build82 as an MCP server in your AI tool:

bash
build82 install [target]

It detects which supported tools are installed and prompts for the Moodle path. Run it without a target to configure every tool found, or pass one explicitly: claude (Claude Code), claude-desktop, antigravity, codex, opencode, cursor, zed, cline.

For example, with Claude Code you can also register it manually:

bash
claude mcp add --scope user build82 -e BUILD82_MOODLE_PATH=/path/to/moodle -- /usr/local/bin/build82

Claude Desktop can also install build82 as a desktop extension: every release ships a build82.mcpb bundle with the binaries included — see Claude Desktop. build82 is also listed in the official MCP Registry as io.github.oito2/mcp-build82.

Per-client guides, including manual configuration: MCP Clients. To remove it: build82 uninstall [target] — see Uninstallation.

Update & Maintenance

bash
build82 self-update --check    # report whether a newer release exists, without installing itbuild82 self-update            # download, verify, and install the latest releasebuild82 self-update --rollback # restore the previous binary if the new version turns out to be broken

Downloads are checksum-verified against the release's checksums.txt and smoke-tested before the running binary is replaced; the previous binary is kept as <path>.bak, which --rollback restores with an atomic rename. If no backup exists, it fails with a clear error and nothing is changed.
