# list_bookmakers

List the bookmakers available on your tier. Returns the curated catalogue (each with key, name and class = "sharp" | "asian") plus a note on tier coverage. Free tier excludes the sharp book (Pinnacle). Use the returned key values in the bookmakers filter of get_match_odds / compare_lines.

## Why list_bookmakers is rated Low

This tool retrieves and queries information about available bookmakers and their metadata (key, name, class, tier coverage). It has no side effects, does not modify data, and serves a purely informational purpose. It fits squarely within the Read category as a data retrieval operation.

From the tool's own definition: "Tool description states it 'List[s] the bookmakers available' and 'Returns the curated catalogue'. The server description emphasizes 'Read-only' access. No modification, deletion, or execution of operations occurs."

## Use case

AI agents call list_bookmakers to retrieve information from Infersports 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 Infersports:

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