Salty vs Attio
The agent-native CRM vs the AI-native CRM.
Salty and Attio are both modern, MCP-equipped CRMs, but they target different users: Attio is an AI-native CRM with a polished UI, a flexible data model, and an AI Research Agent, priced per seat ($29–$69/seat/mo), while Salty is agent-native with no UI at all, priced per API call ($20/mo for 100,000 calls). Both ship a first-party hosted MCP server and a REST API; the decisive difference is the pricing model — Attio’s per-seat fees fit poorly when most "users" are bots, whereas Salty’s per-call pricing means a fleet of agents costs the same as one. Choose Attio when humans and agents share a visual CRM; choose Salty when agents are the only users and you want a pure programmable backend.
Salty vs Attio: at a glance
A head-to-head on the dimensions that matter when AI agents — not human reps — are the primary users of your CRM.

| API | REST API (OpenAPI 3.1) | REST API (no GraphQL) |
| Webhooks | HMAC-signed, built-in | Webhooks supported |

What is Salty?
Salty is a developer-first CRM built for AI agents instead of human reps. It exposes one workspace through four programmatic surfaces — a REST API (OpenAPI 3.1), a Model Context Protocol (MCP) server with 15 tools, a CLI, and HMAC-signed webhooks — and prices on API calls rather than per seat. There are no kanban boards, dashboards, or integration marketplace; the agent does the work and Salty is the database underneath.
What is Attio?
Attio is an AI-native CRM for startups and GTM teams, built on a flexible custom data model with email/calendar sync, pipelines, reporting, and no-code automations. Its AI layer includes an AI Research Agent (web research that fills records and triggers workflows), AI Attributes that auto-fill fields, and semantic search across communications.
Pricing: Salty vs Attio
Attio pricing as of June 2026. Verify current figures on the vendor’s pricing page (linked in sources below).
- Free$0500 API calls/mo · 10 records · demo tier (no schema edits, custom objects, or webhooks)
- Solo$20/mo100,000 API calls/mo · 25,000 records · every feature
- Pro$99/mo1,000,000 API calls/mo · 250,000 records · every feature
Pricing is per API call, not per seat — every MCP tool call and REST request counts as one call; admin/billing actions are exempt. Overage is $1 per 10,000 calls (and $0.50 per 1,000 records over cap). There is no per-user fee, so a fleet of agents costs the same as one.

Per seat, billed annually (monthly is ~20% higher). Attio is cloud-only and not self-hostable. See Attio’s pricing page for current figures.
When to choose Salty
- Your CRM users are AI agents — per-seat pricing makes no sense when the "users" are bots.
- You want a pure programmable backend with no UI to maintain, priced per call.
- You want a flat cost as you scale agents, not a per-seat fee per bot.
- You want the AI to live in your agent, not inside the CRM (no vendor model lock-in).
When to choose Attio
- Humans and agents both work in the CRM and you want a polished, fast UI.
- You want built-in AI: a Research Agent, AI Attributes, and native data enrichment.
- You value Attio’s flexible visual data model, pipelines, and reporting out of the box.
- You’re a GTM team that wants AI features without writing any agent code.
The bottom line
Attio is the better choice when humans and agents share a visual, AI-native CRM and you want built-in research and enrichment. Salty is the better choice when AI agents are the only users: it strips the UI and per-seat pricing in favor of a per-call REST + MCP backend, so cost stays flat as you add agents. Both ship MCP — the split is per-seat-UI versus per-call-API.
Salty vs Attio: FAQ
- Does Attio have an MCP server?
- Yes. Attio offers a first-party hosted MCP server (OAuth, one-click for Claude Desktop, Claude.ai, ChatGPT, and Cursor) that can read, create, and update records and run semantic search. Salty also ships a native MCP server (15 tools); the difference is Attio pairs it with a per-seat UI, while Salty is API-only and priced per call.
- Is Salty cheaper than Attio for AI agents?
- Usually, yes. Attio charges per seat ($29–$69/seat/mo), so each agent that needs access is another seat. Salty charges per API call ($20/mo for 100,000 calls, $99/mo for 1,000,000) with no per-seat fee, so a fleet of agents costs the same base price as one.
- Does Salty have built-in AI like Attio’s Research Agent?
- No — and that’s deliberate. Attio embeds AI (Research Agent, AI Attributes, enrichment) inside the CRM. Salty assumes your own agent brings the intelligence and uses Salty purely as the system of record it reads and writes through REST and MCP.
- Can I self-host Attio or Salty?
- Neither is self-hostable today — both are managed cloud products. (For a self-hostable CRM, see Twenty.) Salty’s TypeScript SDK and CLI are MIT-licensed, but the CRM service itself is hosted.
