## Facts

- Homepage: https://github.com/aydinfer/spline-mcp-server
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "getVariable",
    "arguments": {}
  }
}
```

## Why getVariable is rated Low

The 'get' prefix strongly indicates a read operation that retrieves variable data from the Spline 3D design tool. Without evidence of side effects, data modification, or execution capabilities, this falls into the Read category. Confidence is moderate (0.7) rather than high due to the empty description, but the naming pattern is consistent with query/retrieval semantics across the sibling tool ecosystem.

From the tool's own definition: "Tool name 'getVariable' suggests retrieval of data without modification. The description is empty, but following naming conventions, 'get' operations are non-destructive queries."

## Use case

AI agents call getVariable to retrieve information from Spline MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Spline MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "getVariable": {}
  }
}
```

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
