BlastRadius Sentinel for Atlassian Forge

BlastRadius Sentinel is an autonomous SRE and resilience app for Atlassian Forge, built for Codegeist 2026 ($120,000 USD).

It combines Atlassian Rovo Agent, Teamwork Graph Cypher Traversal, and the Model Context Protocol (MCP) to compute deterministic incident blast radius scores (0–100) from pull request diffs, mapping impacted downstream microservices, paging on-call teams, and surfacing Confluence recovery runbooks.

Features

1. Atlassian Rovo Agent (rovo:agent):

   • Native AI teammate configured with system prompts and conversation starters.

   • Triggers Forge actions to calculate risk, query graphs, and locate mitigation guides.

2. Atlassian Model Context Protocol Server (rovo:mcp + webtrigger):

   • Full JSON-RPC 2.0 server adhering to the MCP specification (2024-11-05).

   • Supports tools/list, tools/call, resources/list, resources/read, and prompts/get.

   • Accessible by Claude Desktop, Cursor IDE, and Rovo Dev CLI.

3. Teamwork Graph Cypher Traversal:

   • Queries dependency edges (depends_on, owned_by, on_call) across microservices using GraphQL and Cypher.

   • Distinguishes direct versus transitive downstream impact across Tier 1, 2, and 3 services.

4. Jira Issue Panel (jira:issuePanel):

   • Displays blast radius index, affected service lists, estimated MTTR, and runbook links on Jira issues.

5. Interactive Browser Simulator (docs/index.html):

   • Offline interactive simulator featuring an SVG microservice topology visualizer, real-time risk scorecard, and live MCP terminal.

Testing

Run the automated test suite with Node's native test runner:

npm test

Or directly:

node --test tests/test_forge_app.mjs

All 24 unit and integration tests execute with zero external runtime dependencies.
