Slack-Driven MCP PoC (Slack ↔ LLM Router ↔ MCP ↔ Jira)

This PoC turns Slack into a front-end to control Jira via an MCP server. The design is LLM-model-agnostic: you can route via OpenAI, Claude, or local Ollama. Out of the box, the router supports a simple rule-based fallback and optional Ollama calls.

Chat language: Finnish; code and docs in English (per user preference).

High-Level Flow

Slack (user) → Slack Bolt App → LLM Router (/interpret) → MCP Server → Jira Tool → Slack

Quick Start

1) MCP Server

cd mcp-server
cp .env.local .env
npm install
npm start

Environment (.env):

PORT=8080
# Optional LLM router (local)
OLLAMA_URL=http://localhost:11434
# JIRA
JIRA_BASE_URL=https://your-domain.atlassian.net
JIRA_EMAIL=your.email@example.com
JIRA_API_TOKEN=your_jira_api_token

2) Slack App

Create a Slack App (Bolt for JS). Enable:

  • Slash Commands: /ask, /jira
  • Interactivity

Set environment in slack-app/.env (copy from .env.local).

cd slack-app
cp .env.local .env
npm install
npm start

Environment (.env):

SLACK_SIGNING_SECRET=...
SLACK_BOT_TOKEN=xoxb-...
MCP_BASE_URL=http://localhost:8080

Slash Commands

  • /ask <free-form natural language>

    • Example: /ask näytä avoimet tiketit projektissa SAM
    • Slack app → MCP /interpret → resolves to jira_tool.list_issues

  • /jira create "Summary" --project SAM --type Task

    • Slack app → MCP /jira (direct deterministic call)

Notes

  • Intent Schema is defined in shared/schema/intent.schema.json.
  • Model-agnostic: swap OpenAI/Ollama/Claude by adjusting router in mcp-server/server.js.
  • Security: Do not commit .env. For prod, use a secret manager.
  • Auditing: Add Winston/OpenTelemetry later if needed.
