Documentation

roblox-devforum-mcp

An MCP server that gives an AI coding agent the **Roblox

Developer Forum and the official creator docs**.

When your agent hits a Roblox bug, it can check whether Roblox already has it triaged, read the

accepted answer, and confirm the API before writing Luau.

No API key, no login, no setup.

Install

bash

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

DeepSeek Harness:

bash

dsh plugin --profile web add roblox-devforum-mcp

Any other MCP client:

json

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

Tools

Tool	What it does
`search_devforum`	Search the forum. Filters for category, tag, solved-only, likes and date. Pass several phrasings to run them at once.
`search_bugs`	Search only the bug-report categories, so a hit means somebody reported the same symptom.
`get_thread`	Read a topic as Markdown, accepted answer first, code blocks intact.
`get_replies`	Page through a long thread.
`list_recent`	Latest or top topics in a category or tag.
`list_categories`	Every category and tag slug the filters accept.
`search_creator_docs`	Search the docs by page content; pass `path` to read a page in full.
`get_engine_api`	Signatures, security levels and deprecations from the live API dump.
`check_api_health`	Check APIs before you ship: removed, deprecated, security-gated, yielding.
`get_whats_new`	Recent platform changes — for "this worked last week".
`get_weekly_recap`	Any Roblox Weekly Recap, current or historical.

Every tool is read-only, returns Markdown with source URLs, and stays inside a token budget.

`[answered]` beside a result means a reply was marked as the solution — by whoever opened the

thread, not by Roblox. Roblox does not publish a triage state, so read the thread to see

whether staff replied.

Example

> *"My DataStore:SetAsync keeps failing with `502: API Services rejected request`. Is this on

> Roblox's end?"*

The agent runs `search_bugs` on the error text, `get_thread` on the best hit, then

`check_api_health` before touching your code.

Configuration

All optional.

Variable	Default	Purpose
`DEVFORUM_CACHE_TTL`	`300`	Search cache lifetime, in seconds.
`DEVFORUM_TIMEOUT_MS`	`12000`	Per-request timeout.
`DEVFORUM_DEADLINE_MS`	`24000`	Total time one request may spend, retries included.
`DEVFORUM_MAX_RETRIES`	`3`	Retries on 429 and 5xx.
`DEVFORUM_CONCURRENCY`	`4`	Simultaneous requests to the DevForum.
`DEVFORUM_CDN_CONCURRENCY`	`8`	Simultaneous requests to GitHub-hosted docs.
`DEVFORUM_DOCS_SCAN`	`14`	Doc pages scored per search.
`DEVFORUM_CACHE_DIR`	OS temp dir	Where the API dump and docs index are cached.
`DEVFORUM_BASE_URL`	`https://devforum.roblox.com`	Point at another Discourse instance.

A bad value is ignored, with a note on stderr, and the default is used.

Data sources

Roblox/creator-docs, and the

Roblox-Client-Tracker API dump.
