Best CRMs with an MCP server
An MCP server is common enough now that the question isn't which CRM has one. It's how much of the product it actually exposes, and to which tier.
Close wins on documented depth: its official MCP server exposes 36 tools and ships its own SKILL.md file for agent context. Attio wins on access: its server is available on every tier, including free, so a small team can test it without paying first.
The short answer
- Close's official MCP server (mcp.close.com) documents 36 tools with OAuth 2.0 authentication and works with Claude, ChatGPT, Cursor and n8n, per developer.close.com/mcp.
- Attio's MCP server is listed as a workspace feature on every tier including its free plan (up to 3 seats), per attio.com/pricing.
- HubSpot's official remote MCP server (mcp.hubspot.com) has been generally available since roughly April 2026, with a one-click Claude connector and 9 documented tools covering contacts, companies, deals, tickets, notes and engagements, per developers.hubspot.com/ai-tools/mcp.
CRM MCP servers compared
| CRM | Starting price | MCP tool count | Included from | Best for | Not for |
|---|---|---|---|---|---|
| Close | $9/user/mo (Solo, annual) | 36 documented tools | All tiers | The deepest documented tool coverage among CRMs checked | A team that wants free-tier access to test before paying |
| Attio | Free (up to 3 seats) to $79/user/mo (Pro, annual) | Not itemized publicly by count | All tiers including Free | Testing agent access to a real CRM before committing to a paid plan | A team that specifically wants a published tool count |
| HubSpot | Free (2 users) to $150/seat/mo (Enterprise) | 9 documented tools | Official server available; tier gating not fully detailed | A team already on HubSpot wanting a one-click Claude connector | A team that wants the widest tool coverage available today |
| Pipedrive | Pricing not confirmed from vendor's own site at fetch time | Official server confirmed, tool count not detailed | General availability since around June 2026 | A Pipedrive user wanting per-user OAuth with change-log traceability | A buyer who needs a verified price before deciding; check pipedrive.com directly |
| SalesCrew | $299/mo (Core, unlimited seats) | 145 registered tools | All tiers | A team that wants an agent to reach the CRM's full action set, not a subset | A team that wants proof from existing customers; SalesCrew has none yet |
Figures checked on developer.close.com/mcp, attio.com/pricing, developers.hubspot.com/ai-tools/mcp and Pipedrive's MCP documentation, September 2026. Pipedrive's base pricing page returned no dollar figures at fetch time and is not included above.
How the tool counts actually differ
Close
The most thorough MCP implementation among the CRMs checked here: 36 tools, OAuth 2.0 authentication, and a bundled SKILL.md file that gives an agent context on how to use the tools correctly, not only what they're named. Not for: a team that wants to try it without paying; Close's Solo plan starts at $9/user/month but has no free tier.

The widest access point: MCP is available on the free plan, so a team of up to 3 seats can genuinely test whether agent access to their real data is useful before spending anything. Not for: a team that needs the specific tool list documented up front; the count wasn't itemized on Attio's own pricing page.
HubSpot
The most recognizable name here, with a one-click Claude connector that lowers the setup barrier for a team already inside the HubSpot ecosystem. Its 9-tool count is the smallest of the CRMs confirmed in this comparison, covering the core objects but not the product's full breadth. Not for: a team that wants an agent to reach deep, specialized HubSpot functionality beyond core records.
SalesCrew
Disclosure: SalesCrew is our product. Its 145 registered tools cover every module: contacts and companies, the inbox, cadences and campaigns, the data bank, calls, meetings, approvals, agent control, marketing, the knowledge base, Upwork, billing, users and webhooks, because every UI action has an MCP twin by design rather than a curated subset. Not for: a buyer who wants existing customer proof; SalesCrew has none yet.
When none of these is the answer
If nobody on your team plans to connect an AI client to your CRM, an MCP server is not a reason to choose one product over another. Pick the CRM that fits your pipeline and your budget, and revisit this question if and when agent access becomes something you actually want to use.
It's also worth checking that a wide tool count actually maps to the actions you care about. A server with a hundred narrow tools covering rarely used settings is not more useful to you than one with a dozen tools covering exactly the sends, updates and lookups your team performs daily.
Questions
- How many CRMs actually have an MCP server now?
- More than expected. Among the CRMs and adjacent tools checked for a wider comparison, HubSpot, Attio, Close, Pipedrive, Zoho, folk, Apollo and Airtable all confirmed an official MCP server on their own sites or documentation. It's no longer a rare feature, which changes what's actually worth comparing.
- Does an MCP server mean an AI can do anything in my CRM?
- Only what the server exposes, and only what the token issued to it is scoped to reach. Close's server, for example, exposes 36 documented tools; HubSpot's exposes 9. A wider tool count generally means more of the product's real functionality is reachable, but check the specific tool list rather than assuming full parity with the UI.
- Is a free-tier MCP server actually usable, or a teaser?
- Attio's MCP server is available on its free plan, capped at 3 seats and 50,000 records, which is enough to genuinely test agent access to a real workspace before paying, not only a marketing gesture.
- Which CRM has the most MCP tools?
- Among the CRMs checked, Close's official server documents 36 tools, the highest tool count confirmed directly from a CRM vendor's own documentation in this comparison. Coverage changes as products update, so check current documentation before relying on a specific number.
