About

Wraps the StackExchange API v2.3 to enable reading StackExchange data (questions, answers, etc.) without authentication. Allows AI agents to query StackExchange content through natural language or direct tool calls.

README

StackExchange MCP — wraps the StackExchange API v2.3 (free, no auth required for read)

Part of Pipeworx — an MCP gateway connecting AI agents to 1394+ live data sources.

Tools

Tool Description
search_questions Search for questions on StackOverflow or any StackExchange site. Returns title, body, score, answer count, tags, and link.
get_answers Get answers for a specific StackExchange question by ID. Returns answer body, score, and whether it is accepted.
stack_get_user Look up a StackExchange user by numeric ID. Returns display name, reputation, badges (gold/silver/bronze counts), location, website, account age, last access, and per-site activity counts (questions/answers). Works on any StackExchange site (default: stackoverflow).
list_questions_by_tag Browse questions by TAG, sorted by votes or recency — answers "top questions tagged ", "trending questions this week/month", "most-voted questions". Returns title, score, answer count, whether answered, view count, tags, and link (call get_answers with a returned question_id to read answers). Combine tags with ";" for AND (e.g. "kubernetes;helm"). Distinct from search_questions, which is keyword-based.
stack_tags List or search StackOverflow / StackExchange tags with question counts and synonym info — top tags by popularity, tags matching a name fragment, or stats for specific tags. Answers "most popular StackOverflow tags", "how many questions are tagged X", "which tags have more than N questions". Example: stack_tags({ sort: "popular", limit: 20 }) or stack_tags({ inname: "python" })

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "stackexchange": {
      "url": "https://gateway.pipeworx.io/stackexchange/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 1394+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Stackexchange data" })

The gateway picks the right tool and fills the arguments automatically.
