Overview
The Stack Internal MCP server offers vast power to locate, synthesize, and create content on your site. The use case examples below are just a small sampling of what you can accomplish with the MCP server.
MCP tools
The examples below are written in plain text, which the MCP server parses to call specific MCP tools. For many of the examples below, we reveal the tools the MCP server uses to complete the request.
In most cases, a plain text prompt will deliver the desired results. When you need more control, you can call MCP tools directly. See the MCP Server Quickstart Guide for more information.
Agent instructions
The examples in this article assume you have an instructions file telling the agent to search your Stack Internal content first. If you don't have an agent instructions file setting this default behavior, add "Search Stack Internal first" to each of the relevant prompts below. To learn more about automating agent behaviors with an agent instructions file, see the MCP Server Agent Instructions article.
Search with insight
Use the MCP server to prioritize your company's trusted, tailored knowledge over generic, unverified information.
Ground code in internal standards
Ask your agent about a standard or convention. With the MCP server connected, it searches your Stack Internal site first and returns actionable results. Without it, you get generic patterns.
What's our standard approach to error handling in backend services?
How should I structure logging in this service?
I need to add a new database migration. What's our process?
To see the difference clearly, temporarily disconnect the MCP server and ask the same question. Compare the outputs.
Accelerate onboarding
New hires ask their agent onboarding questions. The agent answers with your team's validated content instead of generic guidance.
How do I run the full test suite locally?
What's our branching strategy?
How is authentication handled in our platform? I'm coming from a team that used OAuth differently.
Prevent hallucinations in sensitive code
For security, compliance, and regulated domains, generic AI output creates risk. The MCP server grounds your agent in your approved patterns for auth flows, PII handling, encryption, and similar topics.
Write a JWT authentication handler.
How do we handle PII in our logging pipeline?
If your team has explicitly deprecated a pattern, you can ask for it by name. The MCP-grounded agent should return the deprecation notice from Stack Internal rather than generating the deprecated approach.
Find the right expert
When no answer exists, the MCP server can locate users who've demonstrated expertise in the desired topic based on their Stack Internal activity (answers posted, votes received, content authored, etc.). If a tag has no activity yet, no experts are returned.
Who on the team is the expert on our CI/CD pipeline?
I have a question about our auth flow but I don't know who to ask. Can you find the right person?
Search Stack Internal for our Kubernetes deployment process. If there's no answer, find the SME I should ask and draft a question.
MCP tools used
In the examples above, the MCP server uses the recommend_SME tool. This tool requires a tag ID, not a tag name, so it first uses get_existing_tags.
Capture knowledge
The MCP write tools let developers contribute knowledge back to Stack Internal without leaving the IDE or application they're using.
Document solutions at the moment of resolution
After debugging an issue or implementing a non-obvious solution, tell your agent to capture it. The MCP agent drafts the Q&A, shows you the draft, and posts after your approval.
We just solved that connection timeout issue. Create a Q&A in Stack Internal documenting the problem and our fix so the next person doesn't hit the same wall.
Draft a Stack Internal question and answer about the database migration issue we just debugged. Show me the draft before posting.
MCP tools used
In the examples above, the MCP server uses the get_existing_tags and draft_question tools.
NOTE: The MCP server automatically tags content it creates with the "ai-generated" tag, giving users visibility into AI-assisted contributions.
Draft incident postmortems
Describe an incident to your agent and have it draft a structured postmortem article or Q&A. Ask it to search for related past incidents first to avoid duplication and guide the result. The agent can structure the draft with a summary, timeline, root cause, resolution, and action items.
Search Stack Internal for any previous incidents involving our payment gateway and draft a Q&A regarding today's outage.
We just resolved a P1 outage. Misconfigured load balancer after a Terraform apply. Downtime: 23 minutes. Draft a postmortem article for Stack Internal.
MCP tools used
In the examples above, the MCP server will use the create_article or create_QA tools to publish content to the site.
Turn knowledge gaps into new questions
When the MCP server can't find relevant content on your Stack Internal site to answer your question, have it draft a new question to address the knowledge gap. If the agent searches and finds nothing, it will create a well-formed question with valid tags for you to review and post.
What's our standard for rate limiting on internal APIs? If you can't find an answer on Stack Internal, draft a question to fill the knowledge gap.
How do we handle graceful degradation when the recommendation service is down? If you can't find an answer on Stack Internal, draft a question to fill the knowledge gap.
NOTE: You can make the MCP server fill knowledge gaps automatically by including the "search yields no results, draft a question" rule in an agent instructions file. See the MCP Server Agent Instructions article for more information.
Curate and maintain
Knowledge bases decay. Use the MCP server to bring curation and content health checks into your existing workflows.
Triage unanswered questions
Ask the MCP server to surface questions without an accepted answer, filtered by topic or tag. You can then have the agent draft answers using related Stack Internal content for you to review and publish.
Find unanswered questions in Stack Internal tagged with "kubernetes". Draft an answer drawing from Stack Internal content.
Draft an answer to question #[ID] based on Stack Internal content and other sources.
I found some unanswered questions pertaining to security. Who are the SMEs for security topics?
MCP tools used
Locating unanswered questions uses the get_questions_to_answer tool. The last example above uses the recommend_SME tool to identify users who could answer the question.
NOTE: It's good practice to review AI-assisted answers for accuracy, then upvote ones you've confirmed to increase their visibility.
Refresh stale content
Use the MCP server to search for content referencing tools, libraries, or patterns your team has migrated away from. Have the agent flag potentially stale items and draft updated answers.
Search Stack Internal for anything referencing Jenkins, as we've migrated to GitHub Actions. List those questions and answers.
Get the answer to question #[ID] and check if it still reflects our current deployment process. If not, draft an updated answer.
Update my answer on question #[ID] to reflect the new Kubernetes-based deploy flow.
MCP tools used
The first example above uses the get_comments tool to check whether others have already flagged the content as outdated.
Vote with MCP
Voting is a simple way to improve the quality and relevance of your site's content, and the MCP server can do it for you. When you read a helpful answer, have the MCP server upvote it. When you spot something outdated or unhelpful, have it downvote that answer.
Upvote the accepted answer. It matched exactly what I needed.
Downvote that answer. It doesn't align with our best practices.
MCP tools used
The examples above use the get_comments tool. The MCP server can read, but not write, comments.
NOTE: You can use agent instructions to have the MCP server automatically upvote content it references and uses. See the MCP Server Quickstart Guide for more information.
