jc-mcp

Token-efficient Jira & Confluence MCP server. Returns lean, flat responses that minimize token consumption while preserving the information LLM agents need.

Quick Start

  1. Get an API token from id.atlassian.com

  2. Add the server to your MCP client:

claude mcp add jc-mcp -- npx -y @maphnet/jc-mcp \
  -e ATLASSIAN_URL=https://yoursite.atlassian.net \
  -e ATLASSIAN_EMAIL=you@example.com \
  -e ATLASSIAN_TOKEN=your-api-token

That's it. CloudId is auto-discovered from your site URL.

Why This Server?

Standard Atlassian MCP servers return raw API responses — deeply nested JSON with metadata LLM agents don't need. jc-mcp flattens and trims every response:

  • jcm_getTransitions: ~200 tokens vs ~6,600 from raw API

  • jcm_getIssue: flat status: "In Progress" vs nested status.name + statusCategory + self links

  • Write operations: return {ok: true, key: "PROJ-1"} — no re-fetch

Less tokens = faster responses, lower cost, more room in the context window.
