Connect (Remote Server) Docs
Overview

Sybill is an AI sales assistant that analyzes meetings, generates call summaries, drafts follow-up emails, and auto-fills CRM fields (MEDDPICC, BANT, custom fields). The official Sybill MCP server exposes this data and intelligence to MCP-compatible clients like Claude Desktop, Cursor, and VS Code Copilot, so AI agents can answer questions across your call transcripts, deals, and accounts using natural language.

The server is hosted by Sybill at https://mcp.sybill.ai/mcp over streamable HTTP, with OAuth-based authentication tied to your Sybill account. It provides seven tools, including a flagship ask_sybill tool that answers free-form questions across your entire dataset, plus structured list/get endpoints for conversations, deals, and accounts. Rate limits mirror Sybill's REST API.

Because the server is hosted by Sybill, there is no self-hosted package or GitHub repository to clone. You point a client at the remote URL via mcp-remote and sign in on first use. Access requires a Sybill account on a plan that includes API/MCP access.

Setup Guide

Prerequisites

  • A Sybill account with API/MCP access enabled on your plan
  • An MCP-compatible client (Claude Desktop, Cursor, or VS Code Copilot)
  • Node.js installed locally so npx can run mcp-remote

Claude Desktop config

Add the following to your claude_desktop_config.json:

{
  "mcpServers": {
    "sybill": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.sybill.ai/mcp"]
    }
  }
}

First-run authentication

On first use, Claude Desktop will open a browser window prompting you to sign in with your Sybill account. After authentication, the OAuth token is cached and the seven tools become available to the model.

Cursor and VS Code Copilot

Sybill documents these clients as compatible. Point them at https://mcp.sybill.ai/mcp using the equivalent remote MCP configuration for each client.

Rate limits and errors

The MCP server shares rate limits with Sybill's REST API. Expect:

  • 401 Unauthorized if the session expires or auth fails
  • 429 Too Many Requests if you exceed your plan's rate limit
  • 500 Internal Server Error for processing failures
Use Cases
  • Ask "What are the top risks in my Q2 pipeline?" and have Sybill synthesize an answer from call transcripts, deal stages, and CRM activity
  • Pull a deal's full history (calls, attendees, transcript snippets, current stage) into Claude to draft a tailored follow-up email or executive briefing
  • List all conversations with a specific account over the last 30 days and summarize sentiment, objections, and next steps
  • Generate a weekly pipeline review by listing deals filtered by stage and amount, then asking the model to flag stalled opportunities
  • Build a custom dashboard or report by feeding Sybill conversation and deal data into Claude and asking it to produce the layout
Example Prompts
  • "Use ask_sybill to tell me which deals over $50k are at risk this quarter and why."
  • "List all conversations from last week tagged as discovery calls and summarize the common objections."
  • "Get the full transcript for my most recent meeting with Acme Corp and draft a MEDDPICC-style follow-up."
  • "Show me deals in the negotiation stage owned by Jamie, sorted by amount."
  • "Pull the account record for Globex, including contacts and open deals, then write a renewal strategy memo."
Pros
  • Official, provider-hosted server with OAuth, so no API keys to manage or rotate
  • Includes a high-level ask_sybill tool that lets the model query across the entire dataset without orchestrating multiple calls
  • Covers the three core Sybill entities (conversations, deals, accounts) with both list and detail endpoints
  • Works with Claude Desktop, Cursor, and VS Code Copilot via standard mcp-remote config
Limitations
  • Requires a Sybill account on a plan that includes API/MCP access
  • Documentation provides explicit setup snippets only for Claude Desktop; Cursor and VS Code users must adapt the config themselves
  • Read-only surface: the documented tools query data but do not appear to create or update conversations, deals, or accounts
