Parse and validate a FOL formula. Returns information about variables, constants, predicates, and whether the formula is syntactically valid.
AI agents call parse_formula to retrieve information from FOL Prover MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool only parses and validates a formula, returning structural information. It has no side effects, does not modify data, and does not execute anything. It is a pure read/analysis operation.
From the tool's definition Parse and validate a FOL formula. Returns information about variables, constants, predicates, and whether the formula is syntactically valid.
Attacks that exploit this kind of access
Parse and validate a FOL formula. Returns information about variables, constants, predicates, and whether the formula is syntactically valid. It is categorised as a Read tool in the FOL Prover MCP Server MCP Server, which means it retrieves data without modifying state.
Register the FOL Prover MCP Server MCP server in PolicyLayer and add a rule for parse_formula: 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 FOL Prover MCP Server. Nothing to install.
parse_formula 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 parse_formula 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 parse_formula. 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.
parse_formula is provided by the FOL Prover MCP Server MCP server (newjerseystyle/folprover-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
