## [HubSpot](https://developers.hubspot.com/ai-tools/mcp)

HubSpot CRM context and actions

75Kestimated installs

**What it is** HubSpot's remote CRM MCP behind its Claude connector and Codex plugin, plus a separate local developer MCP and a beta Agent CLI for bulk or scheduled CRM automation.

**When to use** Ordinary CRM analysis and controlled record updates where HubSpot runs the pipeline; the Agent CLI covers bulk and background operations, with broader write authority to review.

**What you need** A HubSpot account with admin enablement. The conversational connector cannot delete records and excludes HubSpot Sensitive Data properties.

## [Salesforce](https://developer.salesforce.com/docs/platform/hosted-mcp-servers/guide/hosted-mcp-servers-overview.html)

Salesforce CRM data in the agent

65Kestimated installs

**What it is** Salesforce's governed hosted MCP servers bring accounts, contacts, opportunities, activities, and pipeline work into the agent; a native Codex plugin and a separate local DX MCP for Salesforce developers share the same product identity.

**When to use** When Salesforce is the system of record and you want CRM context and follow-up in the agent. The DX route is a different job entirely - org metadata, tests, and DevOps - and its public download numbers describe that developer package, not CRM adoption.

**What you need** A Salesforce org; hosted MCP setup can require an administrator-configured OAuth client.

## [OpenAI Sales](https://openai.com/index/codex-for-every-role-tool-workflow/)

OpenAI's sales bundle for Codex

40Kestimated installs

**What it is** OpenAI's first-party Codex bundle for sellers and managers - twenty skills and thirty optional apps across CRM, meetings, email, calendar, knowledge, enrichment, and document signing.

**When to use** Seller workflows in Codex without forcing the team onto one CRM - admins enable the authoritative CRM and only the supporting apps the team actually uses.

**What you need** Codex only - no Claude version of this bundle exists. It inherits each connected app's permissions; start read-only and review CRM and outreach writes.

Install

Plugin

## [Anthropic Sales](https://claude.com/plugins/sales)

Anthropic's official sales bundle

30Kestimated installs

**What it is** Anthropic's first-party sales bundle: Call Summary, Forecast, and Pipeline Review commands plus account-research, call-prep, daily-briefing, outreach, and competitive-intelligence skills.

**When to use** As a method layer over whatever CRM and meeting tools you connect - the bundle brings the workflow, your connectors bring the data. Pairs naturally with the CRM routes on this page.

**What you need** Currently a Claude-only plugin; it works in Claude Cowork and Claude Code.

Install

## [Apollo](https://www.apollo.io/product/mcp)

Prospect search to sequence in Apollo

25Kestimated installs

**What it is** One hosted MCP over Apollo.io's prospect database, enrichment, CRM records, and outbound sequences, packaged as native Claude and Codex plugins plus a Cursor marketplace entry.

**When to use** Moving from account research to verified contacts to sequence enrollment without leaving the agent, when Apollo is already the prospecting system. Every action stays scoped to the authorizing Apollo user.

**What you need** Any Apollo plan, including free; plan permissions and enrichment credits still limit what the tools can do, and Apollo marks the Claude route beta.

Install

Plugin

MCP

## [Hunter](https://hunter.io/mcp)

Email finding and verification

25Kestimated installs

**What it is** Company discovery, contact search, email finding and verification, enrichment, and Leads management through Hunter's official hosted MCP - its single route on every platform.

**When to use** Replacing guessed contact details with verified emails and confidence signals, at the low-commitment end of prospecting.

**What you need** A Hunter account - MCP is included in all plans, including free; normal request limits and credits apply.

Install

MCP

## [Pipedrive](https://support.pipedrive.com/en/article/mcp)

Pipeline and deals in Pipedrive

20Kestimated installs

**What it is** Pipedrive's official agent routes - a Claude connector, a Codex plugin, and a hosted MCP that Pipedrive still labels beta - covering Pipedrive data and supported CRM actions under your existing permissions.

**When to use** When Pipedrive is the team CRM and you want live deal and pipeline context in the agent. The install count belongs to a community pipedrive-automation skill - evidence that Pipedrive workflows see real agent use, not an adoption figure for the official beta MCP.

**What you need** A Pipedrive account with connector permission; the official MCP remains labeled beta.

Install

MCP

## [Attio](https://attio.com/apps/claude)

CRM records and pipeline in Attio

20Kestimated installs

**What it is** Attio's official Claude connector, Codex plugin, and hosted MCP: search, read, create, and update CRM records, tasks, notes, and pipeline data.

**When to use** When Attio is the team CRM and follow-up work should happen where the conversation is. Review write-capable tools before approving them.

**What you need** An Attio workspace and OAuth; workspace policy may control installation and scopes.

Install

## [ZoomInfo](https://gtm.ai/docs/mcp)

Licensed B2B contact and intent data

15Kestimated installs

**What it is** ZoomInfo's hosted MCP with verified company, contact, intent, and account intelligence, packaged with fourteen GTM workflow skills in its Claude and Codex plugins.

**When to use** Account research, stakeholder mapping, and enrichment grounded in licensed data instead of web summaries. Current tools are read-only.

**What you need** A ZoomInfo subscription plus bulk data credits - recurring monthly credits don't qualify. Admins enable API access per user, and admin-only seats can't use MCP.

Install

MCP

## [Clay](https://www.clay.com/guides/clay-mcp)

Enrichment workflows your RevOps built

15Kestimated installs

**What it is** Clay's data providers, research agents, enrichment, and admin-enabled Clay Functions behind a hosted MCP, with an official Claude connector and a Codex plugin in open beta.

**When to use** When your organization already runs prospecting and enrichment in Clay - reps consume the workflows RevOps built without learning Clay tables. It is not a free contact database.

**What you need** An eligible paid Clay workspace; usage consumes Clay credits, and workspace admins govern rep access and which Functions are exposed.

Install

MCP

## [Salesloft](https://www.salesloft.com/company/newsroom/salesloft-mcp-server-revenue-data-ai-ecosystem)

Cadences plus Clari revenue data

15Kestimated installs

**What it is** The combined data layer of the merged Clari + Salesloft platform: Clari's call intelligence, pipeline inspection, and forecasting are included alongside cadences, activities, engagement data, and write-back. One route covers both, as a native Claude connector and a hosted MCP.

**When to use** Revenue context that connects insight to seller action - inspecting pipeline, prepping from conversations, and acting in cadences from the agent.

**What you need** A Salesloft account, administrator enablement, and the Salesloft Agentic add-on.

Install

Connector

MCP

## [Gong](https://help.gong.io/v1/docs/about-gong-mcp)

Deal and account insights from calls

15Kestimated installs

**What it is** Gong's official read-oriented MCP with three tools - ask\_account, ask\_deal, and generate\_brief - over Gong's AI-generated deal and account insights. It returns generated insights, not raw transcripts or messages.

**When to use** Call prep and deal review grounded in conversation intelligence - asking what happened on an account and getting a brief before the next meeting.

**What you need** Any Gong plan, but AI Ask Anything requires a paid seat; a Gong tech admin sets up the OAuth connection, and every request or brief consumes Gong credits.

Install

MCP

## [Lusha](https://docs.lusha.com/user-guide/mcp/lusha-model-context-protocol-mcp-server)

Verified contacts with easy setup

15Kestimated installs

**What it is** B2B people and company search, verified enrichment, buying signals, and website-visitor data, delivered as a native Claude connector, a Codex plugin, and a hosted MCP.

**When to use** Verified contact data with the cleanest platform-native setup among the prospecting integrations - connect and OAuth, no workflow machinery.

**What you need** A Lusha plan with sufficient credits; the generic MCP route needs an API key from an Admin or Manager role. Don't paste API keys into shared configuration.

Install

MCP

## [Outreach](https://www.outreach.io/platform)

Sequences and deals in Outreach

15Kestimated installs

**What it is** Account, conversation, sequence, and revenue-workflow insights and actions from Outreach, through a Claude connector, a Codex plugin, and a hosted MCP.

**When to use** Meeting prep, objection handling, and pipeline work grounded in the team's actual Outreach data.

**What you need** A licensed Outreach user with the Amplify add-on, admin enablement, and MFA if your organization requires it - a team-level route, not an individual sign-up.

Install

MCP

## [Instantly](https://help.instantly.ai/en/articles/12980002-instantly-mcp-model-context-protocol)

Cold-email campaigns, run live

15Kestimated installs

**What it is** Thirty-one tools across cold-email campaigns, leads, replies, analytics, and sending accounts through Instantly's vendor-hosted MCP.

**When to use** Actual outbound execution - creating, pausing, and replying in live campaigns rather than only drafting sales copy.

**What you need** An Instantly subscription with API access; the MCP itself has no separate fee. The tools change live campaigns, so protect the API key and review write actions.

Install

MCP

## [Reply.io](https://reply.io/mcp/)

Multichannel sequences in Reply

8Kestimated installs

**What it is** Reply's official MCP for multichannel outreach operations: sequence start, pause, and management, lead enrollment, reply-state changes, performance reporting, and account connections.

**When to use** Operating Reply's sales-engagement platform conversationally instead of through its UI or API.

**What you need** A Reply account and personal API key. The route is included in the free trial, but command-level credit consumption varies - not every command is free.

Install

MCP

## [Smartlead](https://helpcenter.smartlead.ai/en/articles/300-smartlead-mcp-server)

Cold-email deliverability checks

7Kestimated installs

**What it is** Campaign insights, lead and sender data, deliverability diagnostics, account health, and performance from Smartlead's official MCP.

**When to use** Outbound diagnostics for existing Smartlead users - deliverability and campaign-health questions answered inside the agent.

**What you need** Claude Desktop only - the route supports SSE transport only, runs through a local mcp-remote bridge, and does not work in Claude web. Node.js and a Smartlead subscription with API access are required.

Install

MCP

## [Common Room](https://www.commonroom.io/product/mcp-cli/)

Signal-based pipeline sourcing

6Kestimated installs

**What it is** Unified buyer signals, product activity, enrichment, and CRM-like context through a hosted MCP, with a workflow-rich Claude plugin and both read and write-back tools.

**When to use** Sourcing pipeline from signals - grounding account research and outreach in one identity-resolved GTM data layer, then writing findings back as records, segments, and notes.

**What you need** A licensed Common Room instance; the Claude connector may require organization installation, and admins can disable MCP access.

Install

Plugin

MCP

## [Close](https://help.close.com/docs/mcp-server)

Query and update your Close CRM

6Kestimated installs

**What it is** CRM search plus read, safe-write, or destructive-write tools over leads, activities, tasks, and pipeline data - a Claude connector, a Codex plugin, and a hosted MCP.

**When to use** Querying and updating Close from the agent with write authority you select by scope.

**What you need** A Close account with OAuth or an API key; leave destructive-write scopes off unless you can govern them.

Install

Connector

Plugin

MCP

## [Amplemarket](https://knowledge.amplemarket.com/articles/8022685319-connecting-to-the-amplemarket-mcp-server)

End-to-end outbound in one MCP

6Kestimated installs

**What it is** One account-scoped MCP spanning people and company search, enrichment, saved searches, lead lists, contacts, accounts, sequences, inbox and outbox, and pipeline analytics.

**When to use** Running an outbound workflow end to end - search through sequence and inbox - inside the agent when Amplemarket is the platform.

**What you need** An active Amplemarket account with per-user OAuth; search is unmetered but enrichment and contact reveals consume credits. The connection requests read and write access, so review sequence and list actions.

Install

MCP

## [6sense](https://support.6sense.com/docs/6sense-model-context-protocol-mcp-1)

Predictive intent and account scoring

5Kestimated installs

**What it is** Proprietary account intelligence - predictive buying stages, 6QA status, keyword intent, engagement trends, and ad campaign performance - through 6sense's official read-only MCP.

**When to use** Prioritizing accounts with buying-intent signals rather than looking up contacts - it adds a layer the contact databases on this page don't have.

**What you need** An open beta gated to 6sense Revenue Marketing customers; the current release is read-only.

Install

MCP

→ Hunter - email finding and verification on any plan, free included; the lowest-commitment start

→ Apollo - search, verify, and enroll in sequence from one MCP; works from a free plan

→ ZoomInfo - licensed contact and intent data, when the depth justifies a subscription plus bulk credits

→ 6sense - predictive intent and account scoring, for deciding which accounts to work

→ Common Room - buyer signals across an identity-resolved GTM layer, with write-back

→ Clay - when RevOps already runs enrichment and reps just consume the workflows

Team-level GTM data, not a self-serve contact database - access is governed by your workspace admins.

→ Anthropic Sales layers pipeline-review, forecast, and call-prep workflows over whatever you connect; OpenAI Sales is the Codex-side equivalent

No choice to agonize over - the route is dictated by your stack. What differs is the gating: what an admin must enable and how much write access you allow.

→ Smartlead - deliverability and account-health diagnostics for existing senders

→ Outreach and Salesloft - sales-engagement platforms brought into the agent; both sit behind paid add-ons, and Salesloft also carries Clari forecasting and call intelligence

→ Gong - read-only account and deal briefs generated from conversation intelligence
