Extracts raw text content directly from URLs without browser rendering. Ideal for structured data formats like JSON, XML, CSV, TSV, or plain text files. Best used when fast, direct access to the source content is needed without processing dynamic elements.
AI agents call get-raw-text to retrieve information from MCP Server Fetch Python without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and transforms web content into text format without modifying, deleting, or executing code. It has no side effects beyond fetching and presenting data. The blast radius of misuse is minimal—at worst, an AI agent could fetch sensitive public data, but cannot alter systems or trigger destructive actions. This is a straightforward Read category tool.
From the tool's definition Tool description states it 'Extracts raw text content directly from URLs' and is 'Ideal for structured data formats like JSON, XML, CSV, TSV, or plain text files.' The verb 'extracts' and the focus on retrieval without modification confirms read-only behavior.
Documented attack patterns abuse exactly the kind of access get-raw-text gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Server Fetch Python, and nothing reaches the server without passing your rules. This is the rule we recommend for get-raw-text:
{
"version": "1",
"default": "deny",
"tools": {
"get-raw-text": {}
}
}get-raw-text is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Extracts raw text content directly from URLs without browser rendering. Ideal for structured data formats like JSON, XML, CSV, TSV, or plain text files. Best used when fast, direct access to the source content is needed without processing dynamic elements. It is categorised as a Read tool in the MCP Server Fetch Python MCP Server, which means it retrieves data without modifying state.
Register the MCP Server Fetch Python MCP server in PolicyLayer and add a rule for get-raw-text: 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 MCP Server Fetch Python. Nothing to install.
get-raw-text 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 get-raw-text 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 get-raw-text. 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.
get-raw-text is provided by the MCP Server Fetch Python MCP server (tatn/mcp-server-fetch-python). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Server Fetch Python, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
