WHAT IT DOES

What fetch does on Mcp Server

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

Parameter	Type	Required	Description
`id`	string	Yes	A facility id/slug from a prior `search` result, e.g. equinix-dc1-ashburn

Parameters from the server's own tool schema.

RISK

Why fetch is rated Low

Retrieves and returns facility metadata without modification or side effects; pure data retrieval.

From the tool's definition Fetch a DC Hub record, returns id, title, text, url, metadata, citable public summary.

RECOMMENDED RULE

The rule that runs fetch safely

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

fetch Allowed

fetch 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": {
    "fetch": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Server, apply this rule, and every fetch call is checked against it from then on.

FAQ

Questions about fetch

What does the fetch tool do? +

Fetch a DC Hub record for an id returned by the search tool (OpenAI Deep Research / ChatGPT connector format). Returns {id, title, text, url, metadata} — a citable public summary of one data-center facility (name, operator, location, status, market). For full structured specs (capacity MW, coordinates) use get_facility or open the url. It is categorised as a Read tool in the Mcp Server MCP Server, which means it retrieves data without modifying state.

What parameters does fetch accept? +

fetch accepts 1 parameter: id. Required: id. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on fetch? +

Register the Mcp Server MCP server in PolicyLayer and add a rule for fetch: 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. Nothing to install.

What risk level is fetch? +

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

Can I rate-limit fetch? +

Yes. Add a rate_limit block to the fetch 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 fetch completely? +

Set action: deny in the PolicyLayer policy for fetch. 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 fetch? +

fetch is provided by the Mcp Server MCP server (https://dchub.cloud/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
