Delega

authSTDIOregistry active

Summary

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.

delega-mcp

MCP server for Delega — the task handoff layer for AI agents.

Connect any MCP-compatible client (Claude Code, Cursor, Codex, etc.) to Delega and manage tasks, projects, and agents through natural language.

Install

npm install -g @delega-dev/mcp

Configure

Add to your MCP client config (e.g. Claude Code claude_code_config.json):

{
  "mcpServers": {
    "delega": {
      "command": "npx",
      "args": ["-y", "@delega-dev/mcp"],
      "env": {
        "DELEGA_API_URL": "https://api.delega.dev",
        "DELEGA_AGENT_KEY": "dlg_your_agent_key_here"
      }
    }
  }
}

Environment Variables

Variable	Default	Description
`DELEGA_API_URL`	`https://api.delega.dev`	Delega API endpoint. Defaults to the hosted API; custom `/api`-style endpoints (e.g. `http://localhost:18890`) are an advanced override.
`DELEGA_AGENT_KEY`	(none)	Agent API key for authenticated requests
`DELEGA_REVEAL_AGENT_KEYS`	`0`	⚠️ Development only. Set to `1` to print full API keys in tool output. Never enable in production: a prompt-injected agent could exfiltrate keys from `create_agent` or `list_agents` responses.

Use https://api.delega.dev as the URL.

Security Notes

Non-local DELEGA_API_URL values must use https://.
Agent keys are passed through environment variables rather than command-line arguments, which avoids process-list leakage.
MCP tool output redacts full agent API keys by default.
Do not set DELEGA_REVEAL_AGENT_KEYS=1 in production. This flag exists for initial setup only. In production, a prompt-injected agent could exfiltrate keys from create_agent or list_agents tool output. Keys are returned once at creation time; use rotate_agent_key if you need a new one.

Tools

Tool	Description
`list_tasks`	List tasks, filter by project, label, due date, completion
`get_task`	Get full task details including subtasks and task links
`link_task`	Attach a branch, commit, PR, or URL link to a task
`list_task_links`	List branch, commit, PR, and URL links attached to a task
`create_task`	Create a new task
`update_task`	Update task fields (incl. `assigned_to_agent_id`)
`assign_task`	Assign a task to an agent (or pass `null` to unassign)
`delegate_task`	Delegate a task: create a child task linked to a parent (parent status flips to `delegated`). Use this for multi-agent handoffs — `assign_task` does not create a delegation chain.
`get_task_chain`	Return the full delegation chain for a task (root + descendants, sorted by depth)
`update_task_context`	Merge keys into a task's persistent context blob (deep merge, not replace), recording provenance source
`get_task_context`	Read a task's persistent context blob, optionally with per-key provenance
`get_context_history`	Read the append-only provenance ledger for a task's context
`find_duplicate_tasks`	Check whether proposed task content is similar to existing open tasks (TF-IDF + cosine similarity). Call before `create_task` to avoid redundant work.
`get_usage`	Return quota + rate-limit info. Hosted API only (`api.delega.dev`); custom endpoints receive a clear error.
`claim_task`	Claim the next available task from the queue for exclusive processing (work-queue semantics). Lease-based: default 300s, configurable 30-3600. Returns the task or reports an empty queue. Hosted API only.
`heartbeat_task`	Extend the lease on a claimed task. Call periodically while working so the claim isn't reclaimed. Hosted API only.
`release_task`	Release a claimed task back to the queue without completing it. Hosted API only.
`set_task_state`	Report `working`, `waiting_input`, or `errored` on a claimed task without extending the lease. Hosted API only.
`complete_task`	Mark a task as completed
`delete_task`	Delete a task permanently
`add_comment`	Add a comment to a task
`list_projects`	List all projects
`get_stats`	Get task statistics
`list_agents`	List registered agents
`register_agent`	Register a new agent (returns API key), optionally with a role preset
`set_agent_role`	Set an agent's role: `worker`, `coordinator`, or `admin` (admin key required)
`delete_agent`	Delete an agent (refused if agent has active tasks)
`list_webhooks`	List all webhooks (admin only)
`create_webhook`	Create a webhook for event notifications, including `task.linked` (admin only)
`delete_webhook`	Delete a webhook by ID (admin only)

Task output format

Task-returning tools (list_tasks, get_task, create_task, update_task, assign_task) render each task with assignment metadata when available:

[#42] Ship the release
  Description: Cut RC, tag, push to npm
  Project: Delega
  Labels: release
  Priority: 3
  Due: 2026-04-20
  Assigned to: Coordinator (#7)
  Created by: planner (#3)
  Completed: no

Assigned to / Created by / Completed by lines are emitted only when the underlying field is populated. Custom /api-style endpoints return a nested agent object so the assignee renders as <display_name> (#id); the hosted api.delega.dev API returns the raw agent ID so it renders as #<id>.

Tasks that are part of a delegation chain also surface the chain metadata:

[#def] Draft intro
  Status: delegated
  Assigned to: Drafter (#3)
  Created by: Coordinator (#7)
  Delegation: depth 1, parent #abc, root #abc
  Delegated by: Coordinator (#7)
  Completed: no
  Context keys: step, findings (2)

Single-task tools (get_task, create_task, update_task, assign_task, delegate_task, update_task_context) use a detail render that pretty-prints the full context blob (truncated at 2000 chars). list_tasks uses the concise list render which shows Context keys: … instead.

get_task also shows attached task links when present:

  Links:
    branch: delega-dev/delega-api phase-3-github — https://github.com/delega-dev/delega-api/tree/phase-3-github
    pr: delega-dev/delega-api 42 — https://github.com/delega-dev/delega-api/pull/42

Delegation chains

get_task_chain returns the full parent/child chain for any task in the chain. Output is indented by delegation_depth:

Delegation chain (root #abc, depth 2, 2/4 complete):
  [#abc] Write report (depth 0, delegated)
    [#def] Draft intro (depth 1, completed)
    [#jkl] Draft conclusion (depth 1, pending)
      [#ghi] Research sources (depth 2, completed)

Nodes are sorted by depth then creation order (matching the API's response ordering).
