Delega

delega-dev/delega-mcp

Connects Claude and other MCP clients to Delega's task coordination API, turning natural language into task operations across multi-agent workflows. You get 18 tools covering the full lifecycle: create, assign, delegate (with parent/child chains), update context blobs, find duplicates via TF-IDF similarity, and retrieve delegation trees. Supports both self-hosted instances and the hosted tier at api.delega.dev. Reach for this when you need persistent task handoffs between agents, not just in-memory chat context. Security defaults redact agent keys in tool output to prevent prompt injection exfiltration. Configuration is stdio based with API keys passed through environment variables rather than CLI args.

Readme

delega-mcp

Maintenance status: Delega’s public hosted service retired on July 28, 2026. This client remains public as a verifiable engineering artifact and for Ryan McMillan’s existing private deployment. New public accounts and hosted access are not available. See the case study.

MCP server for Delega — a production task-coordination system for AI agents.

The package is maintained only where Ryan’s private operational use requires it. The default hosted endpoint accepts existing owner credentials only.

Install

npm install -g @delega-dev/mcp
