[build82 by OITO2 Labs — The MCP for Moodle Developers]

[CI] [Go Reference] [Go Report Card] [Go Version] [Release] [License]

🌐 Language: English · Português

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.

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.

Or build from source (requires Go 1.26+):

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

Client Setup

Register build82 as an MCP server in your AI tool:

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:

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

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.

Documentation

The full documentation site lives in docs/en/index.md (also in Portuguese). Main entry points:

• Quickstart — first run in a few minutes
• Architecture — how build82 works, data flow and design decisions
• Tools, Resources and Prompts reference — every MCP capability in detail
• CLI and Configuration reference — every flag, environment variable and config key
• Example Prompts — what to ask your AI agent
