When building agents in DeepSeek Harness (DSH), enabling the model to accurately understand Roblox API changes or reproduce known community-reported bugs requires the ability to access official documentation and developer forums. Local documentation is often outdated, and forum discussions are fragmented and unstructured. The el4cteo/roblox-devforum-mcp plugin solves this problem by exposing the Roblox developer forum and official creator documentation to the DSH process, so the agent can check known issues and API signatures before writing Luau code.

Plugin Information

  • Name: roblox-devforum-mcp
  • Author: EL4CTEO
  • Category: Web Tool
  • License: MIT
  • Repository: https://github.com/EL4CTEO/roblox-devforum-mcp
  • Catalog Page: https://www.skillhub.cn/plugins/EL4CTEO/roblox-devforum-mcp

Core Features

The plugin provides a set of MCP tools for retrieving community and official knowledge about Roblox:

  • search_devforum: Search the developer forum. Supports filtering by category, tags, solved status (solved-only), and date. Multiple search terms can be provided for concurrent execution.
  • search_bugs: Search the Bug Reports category specifically. A match usually means someone has reported the same symptoms.
  • get_thread: Read the content of a specific thread, returned in Markdown format, with replies marked as solutions displayed first.
  • get_replies: Read the replies in a long thread using pagination.
  • list_recent: List the latest or most popular topics under a specific category or tag.
  • list_categories: List all category and tag slugs supported for filtering.
  • search_creator_docs: Search official documentation by page content, and read the full content of a specific page via the path parameter.
  • get_engine_api: Retrieve signatures, security levels, and deprecation status for engine API classes, enums, data types, and Luau libraries.
  • check_api_health: Before deploying code, check whether an API has been removed, deprecated, has case-sensitivity issues, or is blocked by security mechanisms.
  • get_whats_new: Retrieve recent change information for the Roblox platform.
  • get_weekly_recap: Retrieve Roblox’s weekly recap (past or historical).

All tools are read-only operations that return Markdown-formatted results with source URLs and do not exceed the token budget.

Installation

Install it via DSH’s plugin manager:

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

After installation, the MCP server will be added as a plugin to DSH’s Web Profile.

Typical Usage

Suppose the agent encounters the following error during development: “My DataStore:SetAsync keeps failing with 502: API Services rejected request. Is this on Roblox’s end?”.

  1. The agent calls search_bugs, using the error text as the search term, to see whether anyone else has reported the same API error.
  2. If a match is found, it calls get_thread to read the thread content and confirm whether the error is a platform-side issue and what recommendations the community has provided.
  3. Before attempting to modify the code, it calls check_api_health to verify the current status of the relevant API.

Use Cases and Notes

This plugin is suitable for developers building Roblox games or creating agents with DSH.

  • Permissions and Security: The plugin runs with the privileges of the DSH process. All requests are read-only, and no API Key or login credentials are required.
  • Result Markers: The [answered] marker next to a result indicates that the reply was marked as the solution by the original poster, rather than being officially confirmed by Roblox. Since Roblox does not publicly expose ticket status, read the thread content to determine whether Roblox has responded.
  • Independence: The plugin has no official association or endorsement from Roblox Corporation.

After installation and enabling, your DSH agent gains the ability to access Roblox’s official documentation and community knowledge, allowing it to handle issues in Luau code more accurately.
