Best Sales Plugins, Skills, and MCP Servers in 2026
Research-backed sales plugins, skills, and MCP servers for prospecting, enrichment, CRM workflows, outreach, and deal execution.
Updated July 26, 2026
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.
What it isHubSpot’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 useOrdinary 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 needA HubSpot account with admin enablement. The conversational connector cannot delete records and excludes HubSpot Sensitive Data properties.
What it isSalesforce’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 useWhen 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 needA Salesforce org; hosted MCP setup can require an administrator-configured OAuth client.
What it isOpenAI’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 useSeller 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 needCodex only - no Claude version of this bundle exists. It inherits each connected app’s permissions; start read-only and review CRM and outreach writes.
What it isAnthropic’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 useAs 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 needCurrently a Claude-only plugin; it works in Claude Cowork and Claude Code.
What it isOne 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 useMoving 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 needAny Apollo plan, including free; plan permissions and enrichment credits still limit what the tools can do, and Apollo marks the Claude route beta.
What it isCompany 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 useReplacing guessed contact details with verified emails and confidence signals, at the low-commitment end of prospecting.What you needA Hunter account - MCP is included in all plans, including free; normal request limits and credits apply.
What it isPipedrive’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 useWhen 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 needA Pipedrive account with connector permission; the official MCP remains labeled beta.
What it isAttio’s official Claude connector, Codex plugin, and hosted MCP: search, read, create, and update CRM records, tasks, notes, and pipeline data.When to useWhen Attio is the team CRM and follow-up work should happen where the conversation is. Review write-capable tools before approving them.What you needAn Attio workspace and OAuth; workspace policy may control installation and scopes.
What it isZoomInfo’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 useAccount research, stakeholder mapping, and enrichment grounded in licensed data instead of web summaries. Current tools are read-only.What you needA 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.
What it isClay’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 useWhen 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 needAn eligible paid Clay workspace; usage consumes Clay credits, and workspace admins govern rep access and which Functions are exposed.
What it isThe 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 useRevenue context that connects insight to seller action - inspecting pipeline, prepping from conversations, and acting in cadences from the agent.What you needA Salesloft account, administrator enablement, and the Salesloft Agentic add-on.
What it isGong’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 useCall prep and deal review grounded in conversation intelligence - asking what happened on an account and getting a brief before the next meeting.What you needAny 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.
What it isB2B 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 useVerified contact data with the cleanest platform-native setup among the prospecting integrations - connect and OAuth, no workflow machinery.What you needA 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.
What it isAccount, conversation, sequence, and revenue-workflow insights and actions from Outreach, through a Claude connector, a Codex plugin, and a hosted MCP.When to useMeeting prep, objection handling, and pipeline work grounded in the team’s actual Outreach data.What you needA 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.
What it isThirty-one tools across cold-email campaigns, leads, replies, analytics, and sending accounts through Instantly’s vendor-hosted MCP.When to useActual outbound execution - creating, pausing, and replying in live campaigns rather than only drafting sales copy.What you needAn 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.
What it isReply’s official MCP for multichannel outreach operations: sequence start, pause, and management, lead enrollment, reply-state changes, performance reporting, and account connections.When to useOperating Reply’s sales-engagement platform conversationally instead of through its UI or API.What you needA 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.
What it isCampaign insights, lead and sender data, deliverability diagnostics, account health, and performance from Smartlead’s official MCP.When to useOutbound diagnostics for existing Smartlead users - deliverability and campaign-health questions answered inside the agent.What you needClaude 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.
What it isUnified 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 useSourcing 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 needA licensed Common Room instance; the Claude connector may require organization installation, and admins can disable MCP access.
What it isCRM 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 useQuerying and updating Close from the agent with write authority you select by scope.What you needA Close account with OAuth or an API key; leave destructive-write scopes off unless you can govern them.
What it isOne account-scoped MCP spanning people and company search, enrichment, saved searches, lead lists, contacts, accounts, sequences, inbox and outbox, and pipeline analytics.When to useRunning an outbound workflow end to end - search through sequence and inbox - inside the agent when Amplemarket is the platform.What you needAn 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.
What it isProprietary account intelligence - predictive buying stages, 6QA status, keyword intent, engagement trends, and ad campaign performance - through 6sense’s official read-only MCP.When to usePrioritizing 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 needAn open beta gated to 6sense Revenue Marketing customers; the current release is read-only.
→ 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.
