Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00088 | $0.01531 |
| Opus 5 | $0.00044 | $0.00766 |
| Sonnet 5 | $0.00018 | $0.00306 |
| Haiku 4.5 | $0.00009 | $0.00153 |
Grade A, and why
nemoclaw-email-policy scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

NemoClaw Email Policy
NemoClaw enforces network-level policies for AI agents. For email workflows, this means controlling which endpoints agents can reach — and which actions they cannot take — regardless of what the agent itself tries to do.
This is defense in depth: even if an email MCP server has a bug, or an agent hallucinates a send command, the network policy blocks the request before it reaches Microsoft's servers.
Why Policy Enforcement Matters
Email agents have access to sensitive data (inbox contents, contacts, calendars) and can take impactful actions (send email, create calendar events, modify inbox rules). In production, "the agent is well-behaved" is not a sufficient security model.
Failure modes without policy enforcement:
- Agent sends an email to an unintended recipient because of a hallucinated address
- A prompt injection in an email body tricks the agent into forwarding the message
- Agent creates an inbox rule that forwards all email to an external address
- A bug in the MCP server sends a draft that was not approved
NemoClaw prevents these by controlling the network layer — the agent process cannot reach endpoints that are not explicitly allowed.
Prerequisites
- macOS (NemoClaw uses the macOS sandbox)
- NemoClaw installed:
npm install -g nemoclawor clone from GitHub - Email MCP server configured: e.g.,
email-agent-mcpwith Microsoft 365 OAuth completed
Setting Up the Outlook Preset
NemoClaw ships with a curated Outlook preset that allows the minimum necessary endpoints for Microsoft 365 email.
Apply for the current session
openshell policy set nemoclaw-blueprint/policies/presets/outlook.yaml
This enables access to:
graph.microsoft.com— Microsoft Graph API (GET, POST, PATCH)login.microsoftonline.com— OAuth token refreshoutlook.office365.com— Outlook backendoutlook.office.com— Outlook web (for draft links)
All connections require TLS. The preset blocks all other outbound network access.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

nemoclaw-email-policy is a skill published in the GitHub repository UseJunior/email-agent-mcp (6 stars, last pushed 3d ago), licensed Apache-2.0. It adds 88 tokens to every session and 1,531 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
