AI agents call navi_sheets_reader to retrieve information from Navi X402 without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
url | string | Yes | Full spreadsheet URL or just the document ID |

sheet | string | — | Tab name or gid (default: first tab) |

include_formatting | boolean | — | If true, adds per-cell formatting: colors, bold, alignment (default false) |
Parameters from the server's own tool schema.
The tool purely retrieves and returns spreadsheet data as JSON with no side effects. It is explicitly read-only ('view-only share links'), making it a clear Read category. Severity is low since it only reads shared/public documents. The per-call USDC payment is a micropayment infrastructure fee, not a financial transaction initiated by the tool's core function.

Reads any shared online spreadsheet as typed JSON: paste the document URL or ID, get typed columns, rows, pagination, optional per-cell formatting (colors, bold). Works with view-only share links; private documents get clear setup instructions before any payment. (Paid via x402: $0.003 USDC per call on Base, settled automatically.). It is categorised as a Read tool in the Navi X402 MCP Server, which means it retrieves data without modifying state.
navi_sheets_reader accepts 5 parameters: url, limit, sheet, offset, include_formatting. Required: url. The full parameter table on this page comes from the server's own tool schema.
Register the Navi X402 MCP server in PolicyLayer and add a rule for navi_sheets_reader: 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 Navi X402. Nothing to install.
navi_sheets_reader 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 navi_sheets_reader 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 navi_sheets_reader. 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.
navi_sheets_reader is provided by the Navi X402 MCP server (navi-x402-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
