Overview

AI-generated overview

Bullpen is a remote MCP server for an AI sales team that calls companies, reaches real people, and hands them to your rep.

What you can do
  • Talk to Herman, the manager agent, and confirm or cancel the calls, texts and Salesforce updates it proposes
  • Find and research companies, watch them for buying and risk signals, and answer questions from the workspace's own calls, notes and docs
  • Run calling campaigns: create one, import contacts from CSV, and send the crew to work it
  • Reach people by phone: dial through menus and hold to a human, leave a hello on a company line, send texts and emails, and watch live and recent calls
  • Manage the workspace: onboarding checklist, team invites, mobile number, phone lines, crew hiring, Salesforce and Google connections, credits and payment links
When to use it
For outbound sales work where an assistant should prospect companies, run calling campaigns, and get a human on the phone before connecting your rep. Also useful for checking workspace status, credits and onboarding steps from an agent.
Requirements
Remote Streamable HTTP endpoint; nothing to install. Sign in through OAuth 2.1 with PKCE, or send a workspace API key as an Authorization Bearer header. Paid signup and top-ups use the Machine Payments Protocol with Stripe, and card checkout links open in a browser.
Before you install
It spends real money: prepaid credits at $0.30 per crew minute, $0.03 per text and $3 per month per number, with signup and top-ups paid through Stripe. Calls, texts and emails reach the outside world, so only confirm pending actions your principal actually wants. Outbound stays locked until an admin accepts the Outbound Compliance Agreement with their typed name. The API key acts as the member who approved it; revoke it in settings.

Installation

In SourceWeft

  1. Open Bullpen in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/sale.bullpen%2Fbullpen/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

Bullpen MCP server

[mcptry]

Bullpen is an AI sales team that works the phone. A crew of AI callers, each with its own number and voice, gets through phone trees, hold queues and AI receptionists to a real person, then drops your rep into the live call. Every call writes to Salesforce. Herman, the manager agent, runs the whole bullpen in plain language and asks before anything leaves the building.

This repository documents Bullpen's remote MCP server. There is nothing to install or host: the server runs at

https://bullpen.sale/mcp

Connect

Claude (claude.ai, desktop, mobile) Settings → Connectors → Add custom connector → https://bullpen.sale/mcp. The first tool that needs your workspace sends you to bullpen.sale to sign in and click Allow.

Onboard from your agent

Your agent can take a new workspace all the way to live calls. Ask it to run onboarding_status and work the list: switch Herman on, read you the compliance agreement and record your yes, buy a crew line from credits, set your mobile, invite your team. It hands you links for the few steps that happen in your browser (card checkout, Salesforce and Google approval) and a link to the live floor whenever you want to watch.

Agents can hire a bullpen

An agent with a wallet can sign its principal up with no checkout page:

POST https://bullpen.sale/pay/signup?amount=25Content-Type: application/json
{"owner_email": "[email protected]", "company": "Your Co", "agent_name": "your agent"}
  1. The first request returns 402 with an MPP WWW-Authenticate: Payment … challenge (cards via Stripe Shared Payment Tokens).
  2. Pay and retry with Authorization: Payment ….
  3. The response carries api_key, org_id and balance_cents.

Payable endpoints are described with x-payment-info in bullpen.sale/openapi.json. An agent can also attach an AP2 mandate (X-AP2-Mandate) to prove its principal authorized the spend; Bullpen checks every hop's limits and signs a receipt verifiable at /pay/ap2/jwks.

Guardrails

  • A person stands behind outbound. Research, Herman, the brain, company search and campaigns work right away. Calls and texts unlock only after a workspace admin accepts the Outbound Compliance Agreement and adds a phone number.
  • Herman asks first. Anything that reaches the outside world comes back as a pending action; nothing goes out until it's confirmed.
  • Calling rules: company lines only unless the person gave written consent, calling hours in the callee's time zone, opt-outs honored, and the crew says it's an AI when asked.
  • Permissions: a token acts as the member who approved it, in that workspace, with that member's role. It can't buy numbers, change billing, connect accounts or invite people. Revoke it any time in Settings → API keys.

Pricing

Usage-based, prepaid credits: $0.30 per crew minute (no extra charge for reaching a human), $0.03 per text, $3/month per number. New workspaces start with $10. Spending tools return a 402 error at zero. Full table: bullpen.sale/pricing.
