Connect Perplexity to Meltwater MCP

Route a research question through Meltwater from Perplexity. Every client connects to the same Meltwater MCP server, so the URL and sign-in are the same wherever you use it.

Connection details​

SettingValue
Server URLhttps://api.meltwater.com/v2/mcp
TransportStreamable HTTP
AuthenticationOAuth sign-in at app.meltwater.com, or a Meltwater API token in the apikey header

Before you start​

  • A Meltwater account with access to Meltwater MCP.
  • The server URL, exactly https://api.meltwater.com/v2/mcp, with no trailing slash.
  • A Perplexity account. Organization members need an admin to allow custom connectors.

Connect​

1. Open custom connectors​

Perplexity's help center says to open Account settings, then Connectors, then + Custom connector, and choose Remote. Organization admins use Enterprise settings, Permissions, Connectors permissions. An admin has to allow members to add custom connectors before that works for everyone else.

2. Enter the remote server​

Set the name to Meltwater and the MCP server URL to the public endpoint. HTTPS is required. Set Transport to Streamable HTTP. For Authentication, choose OAuth if the form offers it. If discovery fails and the form requires a client id and secret, do not invent them. Meltwater's authorization-server metadata is on https://app.meltwater.com. The same well-known path on api.meltwater.com returns 404.

3. Confirm the tool list​

Open a new conversation and ask the assistant to list the Meltwater tools it can call.

An empty list means either the account can't see any tools, or the client is still using a failed connection. After you fix authentication, start a new chat so the client runs initialize again.

Check the connection​

Once the server shows as connected, paste this prompt into a new conversation. It only uses tools the client has actually listed.

First session
I just connected Meltwater. Use the Meltwater MCP tools if they are available.

1. Confirm the connection by listing the tools you can call. If none are listed, say so and stop.
2. Ask me which brand, company, or topic to brief if I have not named one.
3. Use the available tools to pull recent coverage and the main narratives. Cite the source and date for each material fact the tools return.
4. Return a short briefing: what is being said, what changed, what is unresolved, and one recommended next action.
5. Before calling a tool, check its schema. Ask only for missing inputs, in a single message, then name the tools you will call.
See which tools you can access

Use the Tools Explorer to browse the tools available to your account - each tool's name, description and parameters - without connecting a client.

If it does not connect​

The URL is rejected

Use HTTPS and the exact URL https://api.meltwater.com/v2/mcp. A trailing slash, an http:// scheme, or any other Meltwater URL won't reach the server.

The client only offers SSE

Choose Streamable HTTP, which uses POST. An unauthenticated GET, POST or DELETE to the server URL returns 401 with the body no bearer token.

Tools stay empty after sign-in

Start a new chat so the client runs initialize and tools/list again. Check that the Meltwater account you signed in with has access to Meltwater MCP.
