These extensions cover the three ways sales teams use agents today: prospecting and enrichment tools that put verified contact and intent data behind the agent, CRM routes that bring pipeline and deal context into the conversation, and outreach platforms the agent can operate directly. Almost all are official vendor integrations - expect account requirements, and in a few cases add-ons, stated on each card.

HubSpot logo
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 logo
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 logo
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 logo
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

Plugin
Apollo logo
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.

Hunter logo
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 logo
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.

Attio logo
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.

ZoomInfo logo
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.

Clay logo
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.

Salesloft logo
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.

Gong logo
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 logo
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.

Outreach logo
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.

Instantly logo
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 logo
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 logo
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 logo
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.

Close logo
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.

Amplemarket logo
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 logo
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

Just need a verified email or direct dial?

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

Amplemarket - search all the way through sending in a single connection

Sourcing from buying signals or in-house enrichment?

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.

Working your CRM and pipeline from the agent?

→ Connect the CRM you already run - HubSpot, Salesforce, Pipedrive, Attio, or Close

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.

Running cold-email campaigns at scale?

Instantly - create, pause, and reply in live campaigns, not just draft copy

Smartlead - deliverability and account-health diagnostics for existing senders

Running team cadences and multichannel sequences?

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

Reply.io - multichannel sequences for smaller teams

Prepping calls and reviewing deals?

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

On Salesloft already? Its Clari side answers the same deal-review questions.
