Tools
| Tool | Description | Behaviour |
|---|---|---|
| accept_outbound_agreement | Accept the agreement on your person's behalf ONLY after they have read it and told you they agree. Requires their full name as they typed it; recorded with this connection. Admin or manager only. | Changes data |
| ask_brain | Answer a question from the workspace's own knowledge (calls, notes, docs), with sources, limited by the key's role. | Read-only |
| ask_herman | Talk to Herman, the manager agent who runs the whole bullpen in plain language: status, finding companies, running campaigns, sending the crew to call. Anything that reaches the outside world comes back as a pending action with an id — nothing goes out until confirm_herman_action. | Changes data |
| bullpen_about | What Bullpen does, what it costs, and how an agent gets a workspace and API key. Call this first if you have no key. (No API key needed.) | Read-only |
| bullpen_signup | Start creating a Bullpen workspace for your principal by paying with the Machine Payments Protocol (MPP, Stripe). Returns the 402 payment challenge and the exact URL to retry with your MPP client (e.g. `npx @stripe/link-cli mpp pay <url>`). The paid retry returns an api_key; pass it to this MCP server as `Authorization: Bearer bp_live_…`. $25–$500, all of it becomes credits, plus $10 free. (No API key needed.) | Changes data |
| buy_credits | A Stripe Checkout link your person opens to add credits by card ($50–$10,000). Agents with a wallet can use top_up_credits instead. | Changes data |
| buy_number | Buy a number: $3/month from prepaid credits (first month charged now). Default is a crew line, and a crew member is put on it right away; for:"me" makes it your person's own caller ID instead. Admin or manager only. Confirm with your person before buying. | Changes data |
| confirm_herman_action | Run or drop a pending action Herman proposed (a call, text or Salesforce update). Only confirm what your principal actually wants. | Changes data |
| connect_google | A link your person opens to approve Google Calendar and Gmail, for booking meetings and sending mail. | Changes data |
| connect_salesforce | A link your person opens to approve Bullpen in Salesforce, so every call writes there. Admin or manager only. | Changes data |
| create_campaign | Start a calling campaign. Add contacts with import_campaign_contacts, then work_campaign. | Changes data |
| credits_status | Prepaid credit balance and recent usage. Spending tools return a 402 error at zero. | Read-only |
| find_companies | Search for companies to sell to (e.g. 'HVAC companies in Salt Lake City'). Returns names, main phone lines and websites. | Changes data |
| floor_state | Live and recent crew calls. | Read-only |
| get_a_human | A crew member dials the number, works the phone menu, hold and AI receptionist until a real person answers, then connects the key's owner into the live call. Spends credits ($0.30 per crew minute; no extra charge when a person is reached). Company lines only unless the callee gave written consent. | Changes data |
| get_outbound_agreement | The full Outbound Compliance Agreement and its version. Show it to your person before accept_outbound_agreement; calls and texts stay locked until it's accepted. | Read-only |
| hire_crew | Put an AI crew member (name, voice, role) on every free phone line so the crew can dial. Run after a number is bought. | Changes data |
| import_campaign_contacts | Add contacts to a campaign from CSV text (header row: company, phone, name, title, email). | Changes data |
| invite_teammate | Invite someone to the workspace by email; they get a sign-in link that lands on the join page. Roles: rep, manager, admin (only admins invite admins). | Changes data |
| knock | Reach a human at a company's main line and leave a short hello pointing to your principal. Business hours, once a week per company. Spends credits. | Changes data |
| list_team | Members (role, whether their mobile is set, Herman on) and pending invites with their links. | Read-only |
| onboarding_status | Checklist of what this workspace still needs before every feature works (Herman, compliance agreement, phone number, crew, your mobile, credits, Salesforce, Google, texting, team), in the order to do them, with the tool or link for each. Start here after signing up. | Read-only |
| open_page | A link your person can open: floor (the live floor: who's on a call right now, and recent calls); human_line (Human line: your mobile and live bridge calls); herman (the app home, with Herman in the corner); campaigns (campaigns); companies (companies found and researched); integrations (phone numbers, texting registration, Salesforce and Google); billing (credits, billing and the Outbound Compliance Agreement); team (members and invites); api_keys (API keys and agent connections (revoke here)). "floor" is the live floor to watch calls. (No API key needed.) | Read-only |
| research_company | Who to ask for at a company returned by find_companies. | Changes data |
| search_numbers | Available US numbers by area code, for the crew's lines. | Read-only |
| send_email | Email from the workspace's agent inbox. | Changes data |
| send_text | Text from the workspace's line. Opt-outs are honored. Spends credits. | Changes data |
| set_mobile | Set the mobile that rings when the crew reaches a person (get_a_human). Yours by default; managers can set a teammate's with user_id (from list_team). | Changes data |
| top_up_credits | Start an MPP credit top-up ($5–$500). Returns the 402 challenge and the URL to pay and retry with your MPP client, sending your key as X-Bullpen-Key. | Changes data |
| turn_on_herman | Switch Herman on for this member so ask_herman works. | Changes data |
| watch_companies | Add companies to Social Intel, which scans them for buying and risk signals. | Changes data |
| whoami | The workspace, member and role this API key acts as. | Read-only |
| work_campaign | Send the crew to work a campaign's contacts now. Spends credits. | Changes data |
