Where to find it: OpenAI Plugin Directory: in review. The MCP path below works today.
Set it up
- Open ChatGPT (desktop app) and go to Plugins in the sidebar, then the MCPs tab.
- Press Add server. Name it SignalRaven, choose Streamable HTTP, and paste the URL.
https://api.signalraven.ai/mcp
- Leave the token and header fields empty. Save, then press Authenticate. SignalRaven's sign-in opens in your browser; sign in and press Allow. The consent screen lists what ChatGPT will be able to read.
- Back in ChatGPT, switch to Work at the top of the window. Custom servers attach to Work sessions.
- Open the Plugins chip under the composer and turn SignalRaven on for the session. Pick any model except Instant, which answers without tools.
- Send your first prompt.
Using SignalRaven, show my strongest signals this week.
Your first prompt
Using SignalRaven, show my strongest signals this week.
A ranked list of this week's signals: the person, their title and company, the urgency score out of 10, and why it matters, with a suggested opener for each. An account without a workspace gets the same shape with clearly labeled sample data.
What to ask
- Show my strongest signals this week and draft an opener for each.
- Which named accounts showed activity this week, and through which source?
- Research [person] before my call: what did they engage with, and what should I say?
- Which of my monitored sources are producing qualified signals, and which are dead?
- Run Account Intelligence on [company] and tell me who to email first.
Skills
Two workflows ship with the plugin and work in any assistant that supports skills. In other clients, the same prompts trigger the same tools.
research-prospect: Who they are, what they engaged with and when, the ICP read, why now, and three talking points.draft-openers: Three openers under 300 characters, each citing what the person actually posted.
Troubleshooting
"SignalRaven isn't exposing its signal feed to me in this chat right now."
The server isn't attached to this session. Start a new session in Work mode and turn SignalRaven on in the Plugins chip under the composer. Chat mode doesn't attach custom servers.
"The @signalraven mention isn't resolving to a callable tool."
Same cause: the server isn't attached. Use the Plugins chip in a Work session rather than an @ mention.
"The connector is installed, but its token is missing the read:signals permission."
The connection was approved before permissions were requested. Delete the server, add it again under a new name, and authenticate; the consent screen now lists the permissions. Re-adding under the same name reuses the old connection without asking again.
"OAuth provider returned invalid_scope."
An older registration. Delete the server and add it again under a new name.
ChatGPT answers from its own knowledge instead of calling SignalRaven.
Switch the model away from Instant. Name the tool in the prompt: "Using SignalRaven, …".
I see sample data instead of my workspace.
The account you signed in with has no active SignalRaven workspace, or you approved the connection while signed in as a different user. Disconnect, sign out of signalraven.ai in your browser, and connect again as the account that owns the workspace. Trial and paid workspaces get live data.
The connector asks me to sign in every time.
Sign-in is remembered for a day per client. Reconnecting under a new client name registers a new client on our side, which starts fresh. Keep one connector per assistant.
Your data
ChatGPTreads your own SignalRaven workspace over an OAuth connection you approve and can revoke. Anything that spends credits or changes where signals are delivered sits behind its own named permission on the consent screen. Monitoring runs on SignalRaven’s infrastructure, and the connector never touches your LinkedIn login, cookies, or session. Accounts without a workspace get clearly labeled sample data.
Also works in
- Codex → The same SignalRaven server ChatGPT uses, inside Codex: research a prospect, list signals, and draft openers from your terminal or editor.
- Claude → Connect SignalRaven as a Claude connector, or install the Claude Code plugin with two skills for prospect research and opener drafting.
- Cursor → Add the SignalRaven MCP server to Cursor and ask about signals, accounts, and openers while you work.
