Discord Bot: Suggest a Fix for My Failed MR
An agent-driven Discord bot that reads a failed GitLab MR's logs, queries an internal knowledge-base MCP for matching past incidents.
How it runs
The automated pipeline, trigger to output.

- LogicAgent synthesizes fix grounded in retrieved runbooks
- OutputReply with suggested fix and matched incident in DiscordDiscord
What it does
This goes beyond explaining the failure — it proposes a fix. When a contributor asks about a failed MR, the agent pulls the failing trace from GitLab, searches an internal custom MCP server (your runbooks and past incident notes) for similar failures, and synthesizes a concrete suggested fix grounded in how the team solved it before.
When to use it
Use this when your CI failures map to a recurring set of known causes (missing migration, stale lockfile, env var drift) that are documented somewhere. It turns tribal knowledge into a self-serve answer and cuts repeat questions to senior engineers.
How it works
- 1A contributor mentions the bot in Discord with their MR ID and asks for help.
- 2The agent fetches the failing job trace from GitLab and extracts the error signature.
- 3It queries the internal knowledge-base MCP for past incidents matching that signature.
- 4The agent reasons over the trace plus retrieved runbooks to draft a specific fix.
- 5It replies in Discord with the suggested fix, the matched prior incident, and a confidence note.
