neo-mcp 0.4.45

MCP server for the Neo AI/ML backend — submit tasks, poll status, read output

neo-mcp (pip)

Python MCP server for Neo — submit AI/ML tasks, poll status, read output, and control task lifecycle from any AI editor.

Install it, set your API key, register with your editor — that's it. Everything else is handled automatically.

Get your API key at app.heyneo.so → Settings → API Keys.

Install

pip install neo-mcp

Requires Python 3.11+.

Tip: use pipx install neo-mcp to install in an isolated environment and avoid conflicts with your project's virtualenv.

Connecting to editors

Replace sk-v1-YOUR_KEY with your actual key.

Claude Code

claude mcp add --scope user neo \
  -e NEO_SECRET_KEY=sk-v1-YOUR_KEY \
  -- neo-mcp

Open a new Claude Code session after running this. Neo tools load at session start.

Scope options: --scope user (global, recommended) · --scope project (writes .mcp.json in current repo) · --scope local (this machine only)

Verify it registered:

claude mcp list

Tools

Tool	Description
neo_submit_task	Submit an AI/ML task. Returns thread_id immediately.
neo_list_tasks	List running and recent tasks — reconnects pollers automatically.
neo_task_status	Check status: RUNNING / COMPLETED / WAITING_FOR_FEEDBACK / PAUSED / TERMINATED.
neo_get_messages	Read full task output when COMPLETED. Capped at ~20 000 tokens.
neo_send_feedback	Reply when Neo asks a question (WAITING_FOR_FEEDBACK).
neo_pause_task	Pause a running task.
neo_resume_task	Resume a paused task.
neo_stop_task	Stop and clean up a task permanently.
neo_list_integrations	List stored third-party API keys (names only — never the value).
neo_add_integration	Register a GitHub PAT / HuggingFace token / Anthropic key / OpenRouter key so Neo tasks can use it as an env var.
neo_test_integration	Call the provider's API to confirm a stored key is still valid.
neo_remove_integration	Delete a stored key from this machine.

Integration tools store credentials locally (file 0o600 under ~/.neo/integrations/, or OS keyring with NEO_INTEGRATIONS_BACKEND=keyring). Keys never leave your machine. See the full guide at docs/INTEGRATIONS.md.

Environment variables

Variable	Required	Description
NEO_SECRET_KEY	Yes	Your Neo API key (sk-v1-...) from app.heyneo.so
NEO_DEPLOYMENT_ID	No	Pin a specific deployment UUID (auto-generated and persisted by default)
NEO_WORKSPACE_DIR	No	Override working directory (useful in Docker)
NEO_READ_ONLY	No	true — expose only status/message tools, disable submit/stop/pause

---

Troubleshooting

Symptom	Fix
neo-mcp: command not found	Re-run pip install neo-mcp and verify your PATH with which neo-mcp
Tools don't appear after registering	Open a new session — MCP tools load at session start, not mid-session
Invalid API key (401)	Re-check your key at app.heyneo.so → Settings → API Keys
Trial or quota ended (403)	Top up at the Neo dashboard
Task submitted but no files written	Daemon failed to start — run neo-mcp doctor to diagnose
Status stuck on RUNNING	Call neo_task_status to check; run neo-mcp status to inspect the daemon
