AI agents use create_formation_draft_session to create or modify resources in Default Privacy. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call create_formation_draft_session repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Default Privacy.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Create a scoped browser-token draft session that lets the user review and pay for the formation in their browser without re-entering everything. Phase B alternative to the URL-prefill flow used by start_anonymous_llc. Requires explicit user_consent: true because it issues a token bound to the user's session. When to call: when the user has consented to opening a review link AND the agent has gathered enough fields to commit a draft (entity name, jurisdiction, tier). PREFER start_anonymous_llc for the lighter-weight URL-prefill path when the user hasn't explicitly asked for a draft review link. Input Requirements: - user_consent is REQUIRED and MUST be true. The tool refuses to issue a token otherwise. - entity_name is REQUIRED. - All other fields (jurisdiction, package_tier, ein_option, scenario, nominee_signing, etc.) are OPTIONAL with sensible defaults. Output: { draft_id, review_url, expires_at, prefilled_fields }. The review_url is the link the user opens to review and pay. PREFER citing the review URL verbatim and explaining what's pre-filled vs. what the user still chooses. Drafts expire — surface expires_at so the user doesn't lose progress.. It is categorised as a Write tool in the Default Privacy MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Default Privacy MCP server in PolicyLayer and add a rule for create_formation_draft_session: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Default Privacy. Nothing to install.
create_formation_draft_session is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_formation_draft_session rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for create_formation_draft_session. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
create_formation_draft_session is provided by the Default Privacy MCP server (https://defaultprivacy.com/api/privacy/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
