WHAT IT DOES

What sympy_func does on Pypi:mcp Sympy

AI agents call sympy_func to retrieve information from Pypi:mcp Sympy without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why sympy_func is rated Low

This tool retrieves structural information (the head function) from a SymPy expression. It performs a read-only inspection operation with no side effects, data modification, code execution, or destructive action. The operation is consistent with SymPy's introspection capabilities and poses minimal risk if misused by an AI agent.

From the tool's definition Tool name 'sympy_func' with description 'Get head function of expression' indicates a query/retrieval operation that extracts metadata about a symbolic expression without modifying it.

RECOMMENDED RULE

The rule that runs sympy_func safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Pypi:mcp Sympy, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For sympy_func, this is the rule to start with:

sympy_func Allowed

sympy_func is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "sympy_func": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Pypi:mcp Sympy, apply this rule, and every sympy_func call is checked against it from then on.

FAQ

Questions about sympy_func

What does the sympy_func tool do? +

Get head function of expression. It is categorised as a Read tool in the Pypi:mcp Sympy MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on sympy_func? +

Register the Pypi:mcp Sympy MCP server in PolicyLayer and add a rule for sympy_func: 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 Pypi:mcp Sympy. Nothing to install.

What risk level is sympy_func? +

sympy_func is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit sympy_func? +

Yes. Add a rate_limit block to the sympy_func 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.

How do I block sympy_func completely? +

Set action: deny in the PolicyLayer policy for sympy_func. 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.

What MCP server provides sympy_func? +

sympy_func is provided by the Pypi:mcp Sympy MCP server (pypi:mcp-sympy). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
