validate_input_files
AI agents call validate_input_files to retrieve information from SPIRED-Stab MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Input file validation is a read operation that checks file format, structure, or content against requirements without making changes to the files or triggering external operations. It has minimal blast radius if called unexpectedly—at worst it returns validation errors.
From the tool's definition Tool name 'validate_input_files' suggests inspection/validation of file contents without modification. The 'validate' verb typically implies checking, not altering data.

validate_input_files. It is categorised as a Read tool in the SPIRED-Stab MCP MCP Server, which means it retrieves data without modifying state.
Register the SPIRED-Stab MCP server in PolicyLayer and add a rule for validate_input_files: 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 SPIRED-Stab MCP. Nothing to install.
validate_input_files 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 validate_input_files 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 validate_input_files. 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.
validate_input_files is provided by the SPIRED-Stab MCP server (macromnex/spired_stab_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
