01 · USE CASES

Agent workflows for Perplexity.

01

Search the web

Use when a difficult question needs ranked web sources and snippets. Returns up to 20 results; accepts up to five queries. Costs $0.005 per successful request, including empty results. A timed-out call may still be charged; retrying spends again.

02

Search the web quickly

Use when routine retrieval needs lower latency and cost. Returns ranked web sources with snippets, up to 20 results. Costs $0.001 per successful request, including empty results. A timed-out call may still be charged; retrying spends again.

03

Submit background web research

Use when a sourced answer needs background research. Stores a paid run; poll get_result with its id. Uses GPT-6 Luna and web search. A timeout may still create and charge a run: do not blindly resubmit; read back a known id or check the provider console first.

02 · ACTIONS

5 Perplexity actions, graded by risk.

These actions come from the Arc0 registry. Your identity, provider permissions and Arc0 policies determine which actions can run.

  • perplexity.get_result
    Get a research result

    Use when checking a stored Agent response by id. Returns status, available answer, citations, sources and usage. One snapshot per call; poll again later for queued or in_progress. Failed, incomplete and cancelled are terminal states, not completed answers.

write

1

Create and change things. Allow, or ask the user first.

  • perplexity.submit_research
    Submit background web research

    Use when a sourced answer needs background research. Stores a paid run; poll get_result with its id. Uses GPT-6 Luna and web search. A timeout may still create and charge a run: do not blindly resubmit; read back a known id or check the provider console first.

destructive

1

Delete, cancel or archive. Ask first, or deny outright.

  • perplexity.cancel_research
    Cancel background research

    Use when an in-flight research run is no longer needed. Acknowledges cancelling; poll get_result for the terminal state. Already-terminal runs are refused. Existing charges may remain. If the outcome is unknown, read the run status before retrying.

03 · POLICIES AND AUDIT

Control access to Perplexity.

After early access is enabled, connect the intended Perplexity account, authorize your AI client and set policies for its tools.

Provider permissions and Arc0 policy both apply. Allow reads, require approval for selected writes, or deny destructive actions. The audit log records execution decisions.

Configure policies and approvals

Example policy choices

  • Read actions: allow where authorized
  • perplexity.submit_research: require approval
  • perplexity.cancel_research: deny

04 · AUTH AND DATA

How Perplexity connects.

Connect Perplexity using API key. OAuth grants the provider scopes shown during consent; API keys and other credentials retain the permissions configured at the provider. Arc0 stores credentials in its encrypted vault and does not pass them to the model. Disconnect to remove access through Arc0; revoke a key at the provider to invalidate it there. Token refresh and provider-side revocation depend on the authentication lane and provider.

The connection serves authorized calls through Arc0 MCP and REST. How Arc0 handles credentials →

05 · AI CLIENTS

Use Perplexity with your AI client.

Request access to Perplexity first. An Arc0 administrator must enable it for your organization before these actions appear. Then authorize your AI client separately. It only receives tools and accounts allowed for that identity.

Perplexity with Claude

Claude Desktop + Claude Code

  1. In Claude Desktop, add Arc0 through the remote MCP settings and use OAuth. Follow the generic remote-client steps if your account’s interface differs.
  2. For Claude Code, run the command below. Open /mcp, select Arc0, and authenticate in your browser. Select your workspace and review access.
  3. Check the connection with claude mcp get arc0.
claude mcp add --transport http --scope user arc0 https://api.arc0.ai/mcp

Perplexity with ChatGPT

ChatGPT on the web

  1. Open Plugins in ChatGPT, select the plus button, then Add custom MCP server.
  2. Name it Arc0, enter the server URL below, and choose OAuth. Use dynamic client registration if asked; no Arc0 API key is needed.
  3. Review the notice and select Create as a plugin. Complete Arc0 sign-in, workspace selection and consent, then install and select the plugin in your conversation. Labels and access vary by account; managed workspaces may require administrator approval.

Perplexity with OpenAI Codex

Codex app + CLI

  1. Run the registration command below. The app and CLI share ~/.codex/config.toml.
  2. Complete browser OAuth, choose your Arc0 workspace, and review access. If authentication does not start, run codex mcp login arc0.
  3. Check codex mcp list, then open a new Codex chat. Inspect an existing arc0 entry before changing it.

Perplexity with Cursor

Remote MCP setup

  1. Add Arc0 in your client’s remote MCP settings using the server URL below.
  2. Choose OAuth, sign in to Arc0, select the intended workspace and review access.
  3. Confirm the server is connected and start with an allowed read. These are generic remote-MCP steps; consult your client’s settings for its current interface.

Perplexity with VS Code

Remote MCP setup

  1. Add a remote HTTP MCP server named Arc0 using the URL below.
  2. Use OAuth and finish Arc0 sign-in, workspace selection and consent.
  3. Confirm discovery succeeds before requesting a read. These are generic remote-MCP steps; client UI and availability may differ.

Perplexity with Any MCP client

Streamable HTTP

  1. Use a client that supports remote MCP over Streamable HTTP. Add the server URL below and choose OAuth.
  2. For a client without OAuth, use a self-bound API key with execute permission in the X-API-Key header. Store it in secret storage or an environment variable, outside source control. Never send both an API key and an OAuth bearer token.
  3. Use the MCP clients guide for the SDK transport example and Embedded identity for business-managed end users.
https://api.arc0.ai/mcp
Full MCP setup and troubleshooting

After setup, ask your agent to find an allowed read action, load its schema, and execute it on the intended account. Check Activity for the receipt. A connected MCP client alone does not confirm a successful provider call.

07 · FAQ

Perplexity and Arc0, answered.

Q01

Does Perplexity work with Claude Desktop and Claude Code?

Yes, after early access is enabled for your organization and you connect the intended account. Use Arc0’s remote MCP endpoint with OAuth. Claude Code has a documented registration command; Desktop uses the generic remote-client setup.

Q02

Can I use Perplexity with OpenAI Codex, ChatGPT and Cursor?

Yes, after early access is enabled for your organization and you connect the intended account. Codex and ChatGPT have setup instructions in Arc0’s MCP clients guide. Cursor uses the generic remote-MCP steps. Tool access remains scoped to the authorized identity.

Q03

Is this the official Perplexity MCP server?

This is Arc0’s integration page, not a claim of an official Perplexity server. Arc0 adds a shared connection, policy and audit experience across apps. Consult Perplexity for its own current MCP offerings.

Q04

Which Perplexity actions are supported?

5 registry-defined actions: 3 read, 1 write and 1 destructive. Provider permissions, access enablement and Arc0 policy determine what can execute.

Q05

Which permissions does Perplexity need?

Connect Perplexity using API key. OAuth grants the provider scopes shown during consent; API keys and other credentials retain the permissions configured at the provider. Arc0 stores credentials in its encrypted vault and does not pass them to the model. Disconnect to remove access through Arc0; revoke a key at the provider to invalidate it there. Token refresh and provider-side revocation depend on the authentication lane and provider.

Q06

Can I restrict writes in Perplexity?

You can deny write and destructive actions or require approval. Provider scopes and Arc0 action policies are separate controls; a policy does not grant additional provider permissions.

Q07

What does Perplexity through Arc0 cost?

See Arc0 pricing for current connectivity plans. The provider may require its own subscription or charge per request. Arc0 plan allowances do not make third-party data or paid actions free.
