Create or update a reusable contact profile. Saved contacts can be referenced when registering domains or updating domain contacts. If a contactId is provided, the existing contact is updated; otherwise a new contact is created.
AI agents use save_contact to create or update resources in Spaceship — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Spaceship environment.
This tool modifies data (creating new contacts or updating existing ones) but does not permanently delete, execute code, or move money. The changes are reversible—contacts can be updated or removed later. This makes it a Write operation rather than Read (which would only retrieve) or Destructive (which would permanently delete).
From the tool's definition The tool 'save_contact' creates or updates a reusable contact profile. The description explicitly states 'Create or update' and 'If a contactId is provided, the existing contact is updated; otherwise a new contact is created.' These actions are reversible…
Attacks that exploit this kind of access
Create or update a reusable contact profile. Saved contacts can be referenced when registering domains or updating domain contacts. If a contactId is provided, the existing contact is updated; otherwise a new contact is created. It is categorised as a Write tool in the Spaceship MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Spaceship MCP server in PolicyLayer and add a rule for save_contact: 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 Spaceship. Nothing to install.
save_contact 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 save_contact 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 save_contact. 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.
save_contact is provided by the Spaceship MCP server (naveenkm007/spaceship-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
