Claude’s connector ecosystem keeps expanding. Anthropic’s directory now lists over 300 third-party connectors used by millions of people every day, spanning revenue tools, creative software, developer platforms, and everyday consumer apps. Connectors work across Claude, Claude Desktop, Claude Code, Cowork, and the API, and once connected, Claude can bring a tool into a conversation on its own when it’s relevant, without you naming it every time.
Below are the 10 connectors worth knowing right now for GTM teams, ranked by score, with a focus on what’s changed since our June list of 10 Claude connectors.
1. Vibe Prospecting
The Vibe Prospecting is one of the most impactful connectors for revenue teams. It allows Claude users to run prospecting and research directly inside chat, pulling company and contact data without needing expensive platforms like ZoomInfo or Apollo. Users can enrich leads, research accounts, and even draft personalized outreach emails based on verified business insights, all without switching tools.
The ROI here is immediate: prospecting time is cut down, costs are lower compared to traditional enrichment platforms, and sales reps can customize messaging faster. Teams can focus on conversations and deals instead of data-hunting.
How to start using Explorium in Claude:
- Sign up to Vibe Prospecting
- Install the Claude connector
- Sign in and describe what you need
Score: 9.5/10
2. Coupler.io
Coupler.io connects Claude to 400+ business data sources, including Google Ads, Meta Ads, HubSpot, Salesforce, GA4, and Shopify, without any code. You build a data flow in Coupler.io with Claude set as the destination, then ask questions in plain language from inside Claude.
The part that sets it apart from a raw API connector is the Analytical Engine sitting in between: it reads the data, runs the calculations, and only passes verified numbers to Claude, instead of leaving Claude to compute metrics like revenue per recipient or blended ROAS on its own from raw records. For GTM and marketing teams pulling numbers across ad platforms, CRM, and analytics tools into one conversation, that pre-processing step is the difference between a quick answer and a number that actually matches the dashboard.
Best for: marketing and RevOps teams doing recurring cross-platform reporting who don’t have engineering resources to build and maintain custom MCP pipelines.
Score: 9.2/10
3. Slack
Slack’s official MCP server is integrated with Slack’s Real-Time Search API and aligned with Slack’s permission and enterprise-key-management model. Claude can search messages, summarize threads, surface decisions and action items, and draft replies before anything is posted.
For teams that run on Slack, this connector gives Claude organizational context that no uploaded document can replicate. Enterprise admins get full controls over which MCP servers users can access, and for most teams day-to-day setup is straightforward.
Score: 9/10
4. Semrush
The Semrush MCP server is available as an official app inside Claude and draws on the API units from your existing Semrush subscription, with no extra Claude fees. Connect it from Customize > Connect your apps.
It gives Claude direct access to live Semrush data for keyword research, competitive traffic analysis, backlink audits, domain comparisons, and ad copy retrieval, all in real time. Claude Code users can pair it with Google Search Console data to build live dashboards combining competitive intelligence with owned performance.
Best for: SEO strategists, content marketers, and growth teams doing regular competitive and keyword research.
Score: 8.8/10
5. Outreach
Outreach’s MCP server reached general availability in February 2026, positioning the company as the first Revenue Orchestration Platform to connect its revenue insights directly to Claude. The connector surfaces sequence performance, deal risk signals, rep activity, and account engagement data inside Claude conversations.
Setup is handled through the Connectors directory: search for Outreach, connect, and authenticate. For sales leaders who want Claude reasoning applied to live pipeline data rather than CRM exports, this remains one of the most complete revenue-side connectors available.
Best for: sales leaders, RevOps teams, and AEs using Outreach as their primary sequencing and pipeline platform.
Score: 8.7/10
6. HubSpot
The HubSpot connector grounds Claude’s responses in real CRM context, letting teams ask questions in plain language, generate charts and visualizations, and take action on insights directly in HubSpot. Marketing teams can segment contacts from campaign data, sales teams can get pipeline summaries, and support reps can pull open tickets sorted by priority.
The caveat remains data hygiene: the connector’s value scales with how clean and structured your CRM data is. When it’s well-maintained, it’s one of the highest-ROI connectors for commercial teams, and native setup takes under ten minutes.
Score: 8.7/10
7. Braze
The Braze MCP server is listed in the official Anthropic connector directory under Sales and Marketing. Once connected with an API key and base URL, Claude gets access to dozens of Braze API functions spanning campaigns, Canvases, KPIs, and segments.
Lifecycle marketers can ask Claude to visualize email open rates over time, analyze top-performing Canvases, or audit custom attributes and suggest a cleanup plan, all conversationally, without exporting data. The connector also supports correlating churn signals with campaign sends or feature releases to help teams recommend retention interventions.
Best for: CRM marketers, lifecycle teams, and retention analysts running campaigns at scale.
Score: 8.6/10
8. Actively
New to the directory as of June 2026, Actively (built by Taurus Labs) brings always-on, per-account agents into Claude. Rather than pulling static CRM fields, Actively synthesizes CRM data, call transcripts, emails, and external signals into a living account picture, then surfaces the next best action.
It’s built for SDRs, AEs, AMs, and revenue leaders who want deep account context without opening five tools before a call. Ask Claude for an account overview ahead of a meeting, a recommended outreach sequence for a specific deal, or a prioritized view of which accounts in your book need attention this week, and Actively’s agents do the synthesis in the background.
Best for: reps and revenue leaders who want account intelligence and next-step guidance without leaving Claude.
Score: 8.5/10
9. G2
G2’s MCP connector lets AI workflows reference verified buyer reviews, research behavior, and competitive insights straight from the G2 marketplace rather than generic web data.
The connector supports buyer intent intelligence (tracking companies researching your category, reviewing intent scores, identifying accounts to prioritize) as well as competitive intelligence showing which products prospects are comparing you against. For GTM teams that already treat G2 as a demand signal source, pulling intent data into Claude alongside CRM context is a meaningful shortcut.
Best for: GTM teams, demand gen marketers, and sales teams using G2 Buyer Intent for account prioritization.
Score: 8.4/10
10. Customer.io
Customer.io publishes an official MCP setup guide, and connecting it lets users pick which workspaces Claude can access from Settings > Connectors. A hosted MCP server URL is also available for teams who prefer adding it as a custom connector.
Once connected, Claude can query journeys and campaigns, analyze segment membership, compare messaging cadences, and identify drop-off points in automated flows conversationally. It’s especially useful for spotting overlapping sends that could be causing audience fatigue and for tying lifecycle campaign performance to conversion data from other platforms.
Best for: lifecycle marketing teams, growth operators, and email-heavy B2B/B2C orgs.
Score: 8.3/10
Conclusion
The revenue stack inside Claude keeps getting deeper. Prospecting (Vibe Prospecting) now sits alongside account intelligence (Actively), sequencing (Outreach), lifecycle engagement (Braze, Customer.io), pipeline intelligence (HubSpot), and competitive and buyer-intent signals (G2, Semrush). Coupler.io and Slack continue to serve as the connective tissue holding multi-tool workflows together, one for reporting across your data stack and one for team communication.
Claude Managed Agents pair with MCP connectors, meaning the same integrations that power your conversations can run in the background as long-running agent workflows. The connectors you install today aren’t just chat augmentations. They’re the foundation of whatever agentic workflows you’ll be running six months from now.
