mcs-mcp
An MCP server (Go binary) that ingests Atlassian Jira board issue transition history, reconstructs workflow semantics, and serves Monte-Carlo/flow diagnostics to AI agents (e.g., forecasting completion dates, capacity/bottleneck analysis, stability/predictability via control charts).
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Self-hosted tool; authentication handled via env vars or cookies. README claims data minimization by dropping sensitive Jira fields (titles/descriptions/assignees) and persisting only analytical metadata (keys/types/status transitions/timestamps/resolution names). It also claims offline/local human-readable caches. TLS enforcement for the Jira/API communication is not explicitly stated; scope granularity is not described (PAT/API token likely broad). Beta nature does not directly imply security issues, but operational practices (permissions, disk protection, log sanitization) are important.
⚡ Reliability
Best When
You run an MCP-capable agent locally/privately and want offline-capable, board-scoped Jira flow analytics and forecasting based on event histories.
Avoid When
You cannot guarantee consistent workflow status sets/order across analyzed issue types, or you require formal REST/GraphQL interfaces with standard cloud reliability guarantees.
Use Cases
- • Monte-Carlo forecasting for work completion time or throughput
- • Backtesting/validating forecasts via walk-forward analysis
- • Diagnosing process stability and special-cause variation (cycle time/WIP/delivery cadence)
- • Bottleneck identification via semantic workflow mapping
- • Flow waste analysis (yield/abandonment)
- • WIP aging/residence-time analysis for stuck/neglected work
- • Capacity planning and stratified analytics by work item type (e.g., bug tax)
- • Retrospective analysis using historical time-travel reference dates
Not For
- • Teams that require strict support for multiple Jira workflows mixed in one analysis (unless all share the same statuses/order)
- • Use cases needing a hosted SaaS API with centralized uptime/SLA and managed operations
- • Environments where storing any human-readable cache/logs on disk is unacceptable
- • Scenarios where customers need an official OpenAPI/REST interface rather than MCP tool calls
Interface
Authentication
Authentication is configured via environment variables in .env. Cookie-based auth is explicitly described as a fallback and may expire or be blocked by Atlassian.
Pricing
No pricing information provided; appears to be a self-hosted open-source binary.
Agent Metadata
Known Gotchas
- ⚠ Workflow discovery assumption: all work item types on a board share the same workflow and status order; mixed workflows may yield unpredictable analytics.
- ⚠ Server currently works on Boards and does not accept passing JQL; recommended workaround is creating a board using query as board-JQL.
- ⚠ Cookie-based Jira auth may break due to expiry/anti-bot measures; prefer PAT/API token modes for stability.
- ⚠ Beta warning: forecasting/math is not thoroughly verified; agent should treat forecasts as provisional and not as a hard decision basis.
- ⚠ Experimental mode requires both env gate (MCS_ALLOW_EXPERIMENTAL) and per-session tool activation; forgetting one step changes behavior.
