# sap_fetch_epoch_page

Fetch an epoch page by session PDA and epoch index. SAP MCP context: Read-only SAP SDK wrapper against the configured Solana RPC and SAP program. Use these reads to inspect current chain state before mutating registry, payment, reputation, memory, or tool accounts. SAP MCP execution guidance: Intent: read/discovery workflow. Pricing: paid read-premium; estimate first, then use sap_payments_call_paid_tool when the runtime cannot replay x402 natively. Routing: paid hosted call; call sap_estimate_tool_cost first, then use sap_payments_call_paid_tool if the runtime cannot handle x402 natively. Signer boundary: hosted reads/builders never receive keypair bytes; value-moving results must be finalized locally when signing is required.

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

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

## Why sap_fetch_epoch_page is rated Low

Retrieves chain state data without side effects. Pure read operation on Solana blockchain.

From the tool's own definition: "Fetch an epoch page by session PDA and epoch index. Read-only SAP SDK wrapper."

## Use case

AI agents call sap_fetch_epoch_page to retrieve information from Sap 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 Sap:

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