Which sales tools have an MCP server. Checked at the source, tool by tool.

Published · each server checked against the vendor’s published documentation the same day

All 13 tools below run an official MCP server of their own: HubSpot, Salesforce, Pipedrive, Attio and Close among CRMs; Instantly, lemlist, Smartlead, HeyReach and Waalaxy for outreach; Apollo, Clay and PhantomBuster for data and automation. Each entry gives the address or how to connect, how you sign in, any plan limit the vendor states, and what the server can do. Community-built servers exist for several of these tools too; this page lists only the ones the vendor runs.

What they do, and what they leave to you

Every server above acts on the people and records you point it at: it sends, enriches, updates and reports. None of them decides which posts, emails and replies come from someone who is ready to buy. That call is left to you, or to whatever your agent improvises from a prompt.

SignalPipe’s MCP server is that missing step. Hand it any text and three AI judges decide whether the author is a real buyer, with a flag when they disagree. Clear-cut text costs nothing. Put it between reading and acting: judge the replies before your outreach tool answers them, judge the posts before your data tool enriches their authors, and judge the message before your CRM opens a deal.

Connect one in Claude Code

Remote servers connect with one command. For servers that sign in with OAuth, run /mcp afterwards and sign in in the browser; servers that take a key get it in a header, as the vendor documents. In Claude or ChatGPT, add the same address as a custom connector instead.

claude code
# a server that signs in with OAuth (PhantomBuster here); then run /mcp
# in Claude Code and sign in when the browser opens
claude mcp add --transport http phantombuster https://mcp.phantombuster.com

# a server that takes a key in a header (lemlist here)
claude mcp add --transport http lemlist https://app.lemlist.com/mcp \
  --header "X-API-Key: YOUR_LEMLIST_API_KEY"

Add SignalPipe beside them

claude code
claude mcp add --transport http signalpipe https://api.signalpipe.io/mcp \
  --header "Authorization: Bearer YOUR_OPERATOR_KEY"

Then ask for the whole job in plain language:

prompt
Check my unread replies in Instantly. Judge each one with SignalPipe's
score_signal, passing the email it answers as context. Show me the replies
classified buying_intent, and update those contacts in HubSpot.
Do not send anything.

Your operator key is in your console. Worked examples: Instantly replies and the Claude Code sales agent. The full tool list is on the agents page.

See a verdict before you connect anything.

Paste a real reply or post into the live panel and watch the three judges decide. Free, and no account needed.

Questions

Does Instantly have an MCP server?

Yes. Instantly runs one at https://mcp.instantly.ai/mcp. It needs an API v2 key from your workspace, sent in the Authorization header or added to the end of the URL, and can list email accounts, read campaign analytics, build lead lists, check unread replies, pause campaigns and add leads.

Does lemlist have an MCP server?

Yes, at https://app.lemlist.com/mcp. You sign in with OAuth, which lemlist recommends, or send an API key in the X-API-Key header. It can audit campaigns, create or update sequences and manage leads.

Does Waalaxy have an MCP server?

Yes, on the Advanced and Business plans only. It is at https://stargate.prod.aws.waalaxy.com/api/mcp, signs in with OAuth 2.1 rather than an API key, and has four tools: read your prospect lists and campaigns, and import LinkedIn prospects into a list or campaign.

Does PhantomBuster have an MCP server?

Yes, at https://mcp.phantombuster.com, with OAuth sign-in. It can launch, check and stop Phantoms, pull their results, search stored leads and build lead lists.

Does HubSpot have an MCP server?

Yes. HubSpot hosts one at https://mcp.hubspot.com with OAuth sign-in, and it can read, create and update contacts, companies, deals, tickets and more.

Does Apollo.io have an MCP server?

Yes, at https://mcp.apollo.io/mcp, with OAuth or an API key in the X-Api-Key header. Search and enrichment through it spend Apollo credits, as they do in the app.

Does Pipedrive have an MCP server?

Yes. Pipedrive launched one on 30 June 2026 at https://mcp.pipedrive.ai/mcp, available on every plan within token limits, with OAuth sign-in. Claude still labels the connector beta.

Do these MCP servers tell you who is ready to buy?

No. They act on the people and records you point them at: they send, enrich, update and report. Deciding which posts, emails and replies come from someone ready to buy is left to you or to your agent. SignalPipe’s MCP server adds that judgement: hand it any text and three AI judges decide whether the author is a real buyer.
