description

Perplexity is an AI-powered search and answer engine that provides real-time, cited answers using large language models. It's designed for knowledge discovery and in-depth research. Read and write Perplexity data through One: asyncchatcompletions, embeddings, websearch, contextualizedembeddings, agent, chatcompletions and more, 8 actions with real parameter documentation. Use whenever the user asks to look something up in Perplexity, create or update a record there, or build code against the Perplexity API.

Perplexity through One

Perplexity is an AI-powered search and answer engine that provides real-time, cited answers using large language models. It's designed for knowledge discovery and in-depth research.

One exposes Perplexity through four MCP tools. The table below carries real action ids from One's knowledge base, so for a common operation you can skip search and go straight to reading the action's parameters.

How to run an action

1. Find the action in the table below, or call search_one_platform_actions with platform perplexity if it is not listed.
2. Call get_one_action_knowledge with the action id. Do this every time, including for actions in this table. The table gives you the id, not the parameters.
3. Call execute_one_action with parameters copied from that knowledge.

Never guess a parameter name, a body field, or an enum value. The knowledge has the real schema, and a guessed field is either a 400 or a silent write of the wrong thing.

Before you start

Call list_one_integrations once and confirm Perplexity is connected. If it is missing, the user has not connected it: say so and point them at https://app.withone.ai rather than reaching for raw HTTP.

Each connection carries an access field. If it reports {"policy": "methods", "methods": ["GET"]} the agent is read-only here, so plan a read-only answer instead of attempting a write that will be refused.

Before a write

Creates, updates, deletes and sends land on a real Perplexity account and cannot be recalled. State the action and the specific target in one line before the first write in a task, and let the user stop you. Reads need no confirmation.

When a call fails

The error comes from Perplexity, not from One. A 400 or 422 means your parameters do not match the schema, so re-read the knowledge and fix the field. A 401 or 403 means the connection needs re-authorizing, which no retry will fix. A 404 means the id is not on this account. A 429 means slow down. Never retry a write more than once: the first attempt may have landed.
