## Description
MCP server that searches the Roblox DevForum and official creator docs so AI coding agents can debug Roblox games against real community and engine knowledge.

## Tools
Capabilities this server exposes over MCP:

- **search_devforum** — Full-text search across the Roblox Developer Forum. Use this first when a Roblox bug, error message, or engine behaviour needs community context: paste the literal error string (e.g. "502: API Services rejected request") or a symptom description. Results are re-ranked to favour solved and recent threads. Follow up with get_thread on the topic_id you want to read.
- **search_bugs** — Search only the DevForum bug-report categories (engine, Studio, cloud services, mobile, website, Creator Hub, purchasing). Use this to answer "is this a known Roblox bug or is it my code?" — a hit means somebody reported the same symptom, with its category, last-activity date and whether a reply was marked as the solution. Roblox does not tag reports with a public triage state, so read the thread with get_thread to see whether staff actually answered.
- **get_thread** — Read a DevForum topic as Markdown: the original post plus the most useful replies, with the accepted answer hoisted to the top. Accepts a topic id or a full DevForum URL. Code blocks are preserved. Use get_replies to page through the rest.
- **get_replies** — Fetch a page of replies from a DevForum topic in post order. Use after get_thread when the answer is buried further down a long thread.
- **list_recent** — Browse a category or tag without a search query. Use release-notes / announcements to check whether a recent Roblox update explains a regression, or scripting-support to see what is breaking for others right now.
- **list_categories** — List the DevForum category tree and the most-used tags. Call this when you are unsure which category or tag slug to pass to search_devforum, search_bugs, or list_recent.
- **search_creator_docs** — Find and read pages from Roblox's official creator documentation (create.roblox.com/docs). Call with `query` to list matching pages, then call again with `path` from a result to read that page in full. Use this for intended behaviour, limits and quotas, and guide-level explanations — pair it with search_devforum for what actually happens in production.
- **check_api_health** — Batch-check Roblox APIs before you ship Luau that uses them. Pass entries like "Humanoid.MoveTo", "BodyVelocity", "Enum.Material.Neon", "task.wait" or "wait" and each is verified against the live API dump and the official docs: does it still exist, is it spelled with the right case, is it deprecated (with the official replacement where the docs give one), is it locked behind a security level normal scripts cannot use, and does it yield. Use this whenever you are about to write or review Roblox code — models often reproduce APIs that Roblox retired years ago.
- **get_engine_api** — Authoritative signature lookup from the live Roblox API dump: a class's properties, methods, events and callbacks with parameter types, security level, deprecation and thread safety. Use this to confirm a method exists, check whether it is deprecated or server-only, or find the right member name before writing Luau.
- **get_weekly_recap** — Read any Roblox Weekly Recap, current or historical. Roblox publishes one every Friday summarising what shipped that week: betas, engine updates, Marketplace and Studio changes. Use `week` to step back through the archive (0 = newest, 1 = the week before, …), `before` to jump to the recap covering a past date, or `list` to see the archive index. To find when a specific feature or regression landed, list the archive and read the recaps around that date.
- **get_whats_new** — A digest of recent Roblox platform changes: the official Weekly Recap, engine Release Notes, and Announcements. Use this when a game regressed for no obvious reason ("this worked last week"), when checking whether a Roblox update explains new behaviour, or when the user asks what is new on the platform. Returns the latest Weekly Recap body plus everything else published inside the time window.

## Claude Desktop Quick Installation
Install path detected from listing signals. Uses `npx` (confidence: high):

```json
"mcpServers": {
  "roblox-devforum-mcp": {
    "command": "npx",
    "args": ["-y","roblox-devforum-mcp"]
  }
}
```

## Documentation

## What roblox-devforum-mcp MCP server does

The roblox-devforum-mcp MCP server gives an AI coding agent read-only access to three Roblox-related sources: the public Developer Forum, the Roblox creator-docs repository, and an API dump from Roblox-Client-Tracker. It is intended for investigating Roblox development issues with current community discussions and platform reference material.

Forum tools can search by category, tag, date, likes, and solved status. A dedicated bug search limits results to bug-report categories, which helps identify discussions about the same symptom. Agents can then load a topic as Markdown, preserve code blocks, place a marked solution first, and fetch additional replies when a thread is long. Category and tag listing tools expose the slugs accepted by the search filters.

Documentation and API tools cover more than keyword lookup. Creator documentation can be searched by page content, and a page can be read in full by supplying its path. Engine API queries return information such as signatures, security levels, and deprecation status for classes, enums, datatypes, and Luau libraries.

## How it works

The roblox-devforum-mcp MCP server uses a standard command-based MCP configuration. The supplied installation command runs the package through npx, and other MCP clients can launch it with the same command and argument. No authentication, Roblox login, or API key is required according to the project documentation.

Every tool is read-only and returns Markdown containing source URLs. Results are kept within a token budget. The server can search multiple phrasings in one forum request, which is useful when an error may be described in different ways by different developers.

For API validation, `check_api_health` can identify removed or deprecated APIs, casing problems, security restrictions, and yielding behavior. `get_whats_new` helps investigate recent platform changes, while `get_weekly_recap` retrieves Roblox Weekly Recap entries from the current or past periods.

## Setup and configuration

Install it with:

```bash
claude mcp add roblox-devforum -- npx -y roblox-devforum-mcp
```

For another MCP client, configure a server whose command is `npx` and whose argument is `-y roblox-devforum-mcp`. The project also documents a DeepSeek Harness plugin command.

All configuration variables are optional. `DEVFORUM_CACHE_TTL` controls search-cache duration, while `DEVFORUM_TIMEOUT_MS`, `DEVFORUM_DEADLINE_MS`, and `DEVFORUM_MAX_RETRIES` control request timing and retries. `DEVFORUM_CONCURRENCY` and `DEVFORUM_CDN_CONCURRENCY` set parallel request limits. Documentation search depth is controlled by `DEVFORUM_DOCS_SCAN`, cached data is stored under `DEVFORUM_CACHE_DIR`, and `DEVFORUM_BASE_URL` can point to another Discourse instance. Invalid values are ignored and the default is used.

## Tools and capabilities
