# Tool approvals for MCP and connector calls

By Steven Van · 2026-10-01

Developers can set require\_approval to "always" or a filter, then approve or deny each call; Python SDK 0.43.8 and TypeScript SDK 0.38.8 add the types.

Perplexity's Agent API can now hold mcp and connector tool calls for review before they run. Setting require\_approval on either tool type turns the check on. Without it, calls still run with no approval, as before.

## How the approval flow works

When a call needs approval, the response includes an mcp\_approval\_request item and the call does not run. To approve or deny it, send an mcp\_approval\_response with previous\_response\_id. For connector calls, the request item also carries connector\_id, the ID of the connector that proposed the call.

## Choosing which calls to review

- Use "always" to review every call.

- Use a filter object to skip approval for selected tools, or for read-only tools.

- Leave require\_approval omitted, null or "never" to run calls without approval.

## Limits with the sandbox

Approvals apply only to connector calls that appear as mcp\_call items. They do not cover commands that use connector credentials inside the Sandbox. For a connector that supports both paths, any policy other than "never", including a filter object, switches it to its MCP tools so calls can pause for a decision. The Sandbox then does not receive that connector's credentials. For GitHub, this means git and gh commands in the Sandbox run without authentication.

## SDK support

The Python SDK 0.43.8 and TypeScript SDK 0.38.8 include the approval types. Details are in Perplexity's MCP approvals and [Connectors](<https://docs.perplexity.ai/docs/agent-api/tools/connectors>) documentation.
