Validate document path and format / ドキュメントパスと形式を検証
AI agents call affinity_validate_document to retrieve information from MCP Affinity Designer Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Validation operations are read-only queries that inspect document properties and formats to verify their integrity or conformance. They have no side effects, do not execute code, do not modify or delete data, and do not involve financial transactions.
From the tool's definition Tool name 'affinity_validate_document' and description 'Validate document path and format' indicate a validation/checking operation that retrieves or queries document metadata and structure without modifying, executing operations, or deleting data.

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Affinity Designer Server, and nothing reaches the server without passing your rules. This is the rule we recommend for affinity_validate_document:
{
"version": "1",
"default": "deny",
"tools": {
"affinity_validate_document": {}
}
}affinity_validate_document is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MCP Affinity Designer Server. Nothing to install.
affinity_validate_document is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the affinity_validate_document 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 affinity_validate_document. 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.
affinity_validate_document is provided by the MCP Affinity Designer Server MCP server (szgk/mcp-affinity-designer). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Affinity Designer Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
