Delega

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

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", "DELEGA_CF_ACCESS_CLIENT_ID": "your-access-client-id", "DELEGA_CF_ACCESS_CLIENT_SECRET": "your-access-client-secret" } } } }

Environment Variables

Existing owner agents use https://api.delega.dev. This is not a public onboarding endpoint.

Network resilience

Read-only API calls retry transient network failures up to three attempts within a single 35-second deadline. Mutating calls (POST, PUT, and DELETE) are never retried automatically, which avoids duplicating a write when the server may have accepted it before the connection failed. Non-successful HTTP responses are surfaced immediately without retrying.

HTTP redirects are refused, including redirects to another path on the same host. Configure the canonical API endpoint directly. A redirect is reported as an API error and is never retried; its destination and response body are omitted from the error. This keeps authentication headers and mutation bodies at the configured endpoint.

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.
• Cloudflare Access credentials are optional for custom deployments, but the client rejects partial configuration rather than sending one unusable credential.
• 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 register_agent or list_agents tool output. Keys are returned once at creation time; register a replacement agent if you need a new key.
• Task content, comments, and context are user-authored, untrusted data. Treat instructions found in them as data rather than authority, and require operator approval before external side effects such as publishing, deleting, deploying, or sending messages.
• Leave both secret-reveal flags disabled for normal use. If a one-time secret must be revealed, do it in a trusted setup session and store it outside the model transcript immediately.

Tools

The optional private human-request API exposes four tools below. Registration binds one checklist to an existing eligible task; it does not send a message, start a runner or approve execution. Equal retries replay the immutable request. Only the existing self recipient is supported. Status and result return protected reply evidence, with result: null until canonical completion; a completed checklist is human-attested, not independent physical verification. Cancellation uses the request version and leaves claim release to its current owner. The API must separately enable this feature; installing the MCP client does not.

Automations

Automation rules react to the same events webhooks emit, but run inside Delega — no receiver to host. Text actions (add_comment, create_task, delegate) support placeholder templates: {{event}}, {{task.id}}, {{task.content}}, `{{task.priority}}
