Generates TypeScript code for an MCP tool definition based on a Swagger endpoint. Priority: CLI --swagger-url > swaggerFilePath parameter.
AI agents use generateEndpointToolCode to create or update resources in Swagger MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Swagger MCP environment.
This tool produces (writes) new code artifacts based on a Swagger endpoint specification. It is generative rather than destructive—the output is reversible code that can be edited, replaced, or deleted by the user. It does not execute arbitrary commands, delete data irreversibly, or trigger financial transactions. It falls into Write because it creates new content (TypeScript tool definitions) as output.
From the tool's definition Tool 'generateEndpointToolCode' generates TypeScript code (creates/produces code artifacts). The description states it 'Generates TypeScript code for an MCP tool definition,' which is a code generation/creation action without irreversible data deletion,…
Documented attack patterns abuse exactly the kind of access generateEndpointToolCode gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Swagger MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for generateEndpointToolCode:
{
"version": "1",
"default": "deny",
"tools": {
"generateEndpointToolCode": {
"limits": [
{
"counter": "generateendpointtoolcode_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}generateEndpointToolCode stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Generates TypeScript code for an MCP tool definition based on a Swagger endpoint. Priority: CLI --swagger-url > swaggerFilePath parameter. It is categorised as a Write tool in the Swagger MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Swagger MCP server in PolicyLayer and add a rule for generateEndpointToolCode: 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 Swagger MCP. Nothing to install.
generateEndpointToolCode is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the generateEndpointToolCode 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 generateEndpointToolCode. 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.
generateEndpointToolCode is provided by the Swagger MCP server (vizioz/swagger-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
