Manage synced addresses for Address History APIs. Cursor pagination for
Part of the Mcp Address History server.

AI agents use manage_address to create or modify resources in Mcp Address History. 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 manage_address 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 Mcp Address History.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Manage synced addresses for Address History APIs. Cursor pagination for. It is categorised as a Write tool in the Mcp Address History MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mcp Address History MCP server in PolicyLayer and add a rule for manage_address: 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 Mcp Address History. Nothing to install.
manage_address 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 manage_address 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 manage_address. 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.
manage_address is provided by the Mcp Address History MCP server (@cryptoapis-io/mcp-address-history). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
