Attio

Top pick

Best for: Startups and modern GTM teams who want a CRM their automations can drive.

9.1

88AI-stack fitOfficial MCP serverREST APIFree plan14-day trial

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.

What's good

Genuinely API-first: every object and attribute is reachable programmatically
Fast, flexible data model that maps to how you actually sell
Clean enough that reps will use it without a fight

What's not

Younger ecosystem than Salesforce or HubSpot, fewer turnkey integrations
Reporting is improving but not yet enterprise-grade

Pricing

Free, paid from $29/user/mo (billed annually)

HubSpot Sales Hub

Best for: Teams that want an all-in-one platform with a vendor that isn't going anywhere.

8.4

85AI-stack fitOfficial MCP serverREST APIFree plan14-day trial

The category default. Deep CRM, big ecosystem, and a real API surface.

HubSpot ships an official remote MCP server that lets agents read, search, and act on CRM contacts, deals, and engagements over OAuth. The CRM REST API is mature and well-documented with date-based versioning, and native Breeze agents sit on the same plumbing.

The verdict: Safe, capable, and well-connected. Just watch the bill as you scale.

What's good

Mature REST API and a huge integration marketplace
Free tier is genuinely usable for early teams
One platform across marketing, sales, and service

What's not

Costs escalate fast once you add seats and Marketing Hub
Power features are gated behind higher tiers

Pricing

Free tools, paid from ~$20/seat/mo

Inflowave

Best for: Agencies and coaches whose pipeline starts in Instagram and other social DMs.

8.2

84AI-stack fitOfficial MCP serverREST APIFree plan7-day trial

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.

What's good

Official MCP server (mcp.inflowave.io/mcp) plus a REST API, so agents can read and write the pipeline
Official Instagram Graph API, so automation carries no ban risk
Unified inbox across Instagram, Messenger, WhatsApp, SMS, email, and voice
Flat pricing with no per-contact fees, and a genuine free plan

What's not

Built around social DMs, narrower than a general-purpose sales CRM
REST API and white-label are gated to the $297+ tiers
Younger product with a smaller integration ecosystem

Pricing

Free plan; paid from $27/mo, agency tiers $149-$497/mo

Twenty

Best for: Technical teams and GTM engineers who want a hackable, ownable CRM.

8.0

83AI-stack fitCommunity MCP serverREST+GRAPHQL APIFree plan

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.

What's good

Open source with a GraphQL + REST API over everything
Self-hostable; you own the data your agents touch

What's not

Younger product, fewer turnkey integrations
Self-hosting needs engineering

Pricing

Open source (free), cloud from ~$9/user/mo

Zoho CRM

Best for: Budget-conscious teams that want a lot of CRM for little money.

7.6

86AI-stack fitOfficial MCP serverREST APIFree plan15-day trial

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.

What's good

Enormous feature set for the price
Zia AI for scoring, predictions, and writing

What's not

UI can feel dated and dense
Best value only inside the broader Zoho suite

Pricing

Free for 3 users, paid from $14/user/mo (billed annually)

How Revenue Directory picks

The method

Every tool here is researched across official docs, live pricing pages, and real user reviews on G2 and Capterra, then scored on four things: fit for the job, real pricing, how well it scales as your team grows, and AI-stack fit (MCP support, API depth, and how cleanly an agent can drive it).

Revenue Directory does not claim to have hands-on tested every tool; nobody honestly has. The ranking reflects deep research and a decade of selling experience, and affiliate links never move a score. More on the method →
