Best HubSpot Sales Hub alternatives (2026)

The CRM built like a data platform. API-first, fast, and friendly to agents.

Attio ships a first-party hosted MCP server at mcp.attio.com (OAuth, official) plus a public REST API over every record and attribute, so Claude and other agents can read and write the pipeline directly.

The verdict: The best CRM foundation if your stack is heading toward agents and automation.

The CRM for teams that live on the phone and in the inbox.

Close ships an official, vendor-supported MCP server at mcp.close.com (HTTP Streamable, OAuth 2.0) plus a complete REST API and webhooks, so agents like Claude can natively log activity, update leads, and trigger sequences.

The verdict: If your reps make calls all day, Close removes more friction than anything else.

An AI-native CRM built for salespeople and the agents working alongside them.

Breakcold runs its own hosted MCP server with regional endpoints (http.us.breakcold.com/mcp/v1 and http.eu.breakcold.com/mcp/v1), OAuth 2.0 for end-user clients and bearer tokens for service agents, and an X-Breakcold-Organization-Id header for multi-org setups. Its 62 tools are generated from the same public OpenAPI contract as the REST API, so agents get parity with the product rather than a read-only subset: people, companies, deals, tasks, notes, custom fields, pipelines, meetings, webhooks, and the multichannel inbox, including sending and replying. Setup guides for Claude, Claude Code, ChatGPT, Codex, Microsoft 365 Copilot, LM Studio, LibreChat, and TypingMind are published in the public github.com/breakcold/mcp repo. It sits below Attio and Close because the surface is documented by the vendor rather than independently verified, it is hosted-only with no self-host path, and there is no listing in Claude's or ChatGPT's own directories yet.

The verdict: A genuinely agent-accessible multichannel CRM at one flat price, held just below the leaders until its MCP claims are independently verified.

An auto-populating CRM for small B2B teams.

Salesflare ships its own official MCP server (mcp.salesflare.com/mcp, free on every plan) that reads and writes accounts, contacts, opportunities, tasks, and pipelines, plus a documented REST API with bearer-token auth and webhooks behind it. It carries a verified listing in Claude's own Connectors directory (under Anthropic & Partners) and a public listing in ChatGPT's Plugins directory, not just a third-party wrapper.

The verdict: A low-admin CRM that backs its AI-native pitch with real, verified agent access.

Agency CRM for social DMs, with an official MCP server and REST API so agents can drive it.

Inflowave ships an official MCP server at mcp.inflowave.io/mcp plus a REST API, so Claude and other agents can read and write leads, conversations, and pipeline directly. API access is gated to the Agency Pro plan and up.

The verdict: A niche but genuinely agent-ready CRM if your lead flow lives in DMs; narrower than a general sales CRM.

The enterprise standard, now with Agentforce baked in.

Salesforce ships official hosted MCP servers with SObject operations that read and write CRM records under field-level security, connectable from Claude, ChatGPT, and Cursor. The platform also exposes mature REST, SOAP, and GraphQL APIs, though governance and setup are heavy.

The verdict: Unmatched power and ecosystem, but you pay for it in money and complexity.

A lightweight, AI-assisted CRM for relationship-led selling.

folk exposes a documented REST API at developer.folk.app plus Zapier and Make integrations. There is no official MCP server, but a community MIT-licensed server (folk-crm-mcp) lets agents reach folk over MCP.

The verdict: The CRM for people who hate CRMs; modern and AI-assisted without the weight.

A pipeline-first CRM that reps actually keep updated.

Pipedrive's REST API and webhooks are well-documented, and community MCP servers let agents read and update deals; native AI is assistant-level, not agentic.

The verdict: The friendliest pipeline CRM for small teams that want momentum, not admin.

The open-source, API-first CRM you can self-host and script.

Twenty is API-first (GraphQL + REST) and open source, so agents can drive every object; community MCP servers exist and self-hosting removes data-access friction.

The verdict: The most agent-friendly CRM foundation if you're willing to build on it.

The easy-to-adopt CRM with a free MCP server on every plan.

Nutshell ships a first-party MCP server (nutshell.com/integrations/claude) with 26 tools, included free on every plan with no usage caps. A REST API plus a legacy JSON-RPC API cover everything else (developers.nutshell.com).

The verdict: One of the cleanest agent-ready CRMs on the market simply because the MCP server is free, not a paywalled add-on.

Enterprise CRM with agentic AI, built into Microsoft 365 and Teams.

Microsoft ships an official Dataverse MCP Server (GA July 2026), natively supported in Copilot Studio and Azure AI Foundry and usable from Claude Desktop, Claude Code, and other MCP clients. The Dataverse Web API (REST/OData) underlies both the MCP server and Copilot in Dynamics 365.

The verdict: The strongest enterprise pick if your org already runs on Microsoft 365 and Teams.

Zoho's lightweight, free-forever pipeline CRM for small business.

Zoho ships an official 'Zoho MCP for Bigin' server connecting to Claude, ChatGPT, Gemini CLI, and VS Code (help.zoho.com/portal/en/kb/bigin/zoho-mcp-for-bigin), available even on lower tiers, alongside standard API/webhook access.

The verdict: The best free-tier CRM on the market right now simply because the free plan ships with an official MCP server too.

A flexible work-OS CRM with a real GraphQL API.

monday CRM ships an official MCP server (the mondaycom/mcp repo, preinstalled on all accounts at no extra cost) that supports CRM actions like creating leads and deals. The platform API is GraphQL-only, exposed at a single endpoint, so agents and integrations build against that.

The verdict: A solid choice if you want one flexible platform across sales and ops.

An affordable, feature-rich CRM with the Zia AI assistant.

Zoho ships official pre-built MCP servers for Zoho CRM (data query, record operations, customization, and workflow) that install into Claude Desktop, Cursor, and VS Code, and the comprehensive REST API v8 covers everything else.

The verdict: The value pick; a ton of capability if you can live with the interface.

The Gmail CRM, with an official MCP server built in.

Streak ships an official MCP server at api.streak.com/mcp (streak.com/integrations/mcp) alongside a documented REST API (streak.readme.io). The MCP server explicitly excludes email content access, which caps how much a connected agent can see.

The verdict: The easiest CRM to bolt an agent onto if your team already runs its pipeline out of Gmail.

Freshworks' AI-assisted CRM with transparent per-seat pricing.

Freshworks has an MCP server for Freshsales, but it's in Beta/Early Access, available on request to Enterprise-plan customers only, not generally available. The public REST API (developers.freshworks.com/crm/api/) is mature and well-documented.

The verdict: A safe, transparently priced CRM, especially if you're already in the Freshworks ecosystem for support or service.

The white-label CRM agencies rebrand and resell as their own SaaS.

GoHighLevel publishes an official REST API (v2, documented at highlevel.stoplight.io) with Basic access on the Unlimited plan and Advanced access on Agency Pro. There is no first-party MCP server; a handful of community-built MCP servers on GitHub wrap the public API, so agent access works today but isn't vendor-maintained.

The verdict: The default pick if you're an agency building a SaaS reselling business, not the pick for a single-company sales team.

One simple plan, unlimited everything, built for small business.

Less Annoying CRM has a documented REST API (v2/v3, api.lessannoyingcrm.com) with API-key or OAuth auth, but no MCP server or AI features are mentioned anywhere on the vendor's site.

The verdict: The CRM to pick when you want zero complexity and one honest price, not agent integrations.

The CRM that lives inside Gmail and Google Workspace.

Copper ships a public REST API (developer.copper.com, API key + OAuth2, 180 req/min) but no official MCP server. Third-party connectors (viaSocket, ContextGate, MCPBundles) expose it to MCP clients unofficially.

The verdict: The easiest CRM to adopt if your team already runs on Google Workspace, less compelling outside it.

CRM and post-sale project management in one system.

Insightly's REST API (v3.1) is available on all paid plans with a Swagger-based SDK. There's no official MCP server; Zapier offers a third-party, unofficial MCP connector for Insightly.

The verdict: A solid pick if the project-management-after-the-sale angle matters more to you than deep AI-agent access.

All-in-one CRM, email/SMS automation, and invoicing for small business.

Keap has a public REST API (v1 and v2, plus legacy XML-RPC) via developer.keap.com with OAuth2 auth, but no MCP server, official or community, was found on its developer portal.

The verdict: A mature all-in-one platform, but priced and structured for businesses that want a managed setup, not a lean self-serve CRM.
