Attio vs Salesforce
Both of these are official MCP servers for a CRM, but they represent two different eras and philosophies of customer data, and the servers expose very different surfaces. Attio's server is a hosted, OAuth-secured integration to the modern, flexible CRM: an agent can search and list records across people, companies, deals, and custom objects, retrieve full record detail by ID, create, upsert, and update records, inspect attribute definitions, and work with lists, list entries, and notes. Salesforce's offering is the official DX MCP Server, a security-first, developer-oriented integration that operates against orgs you have locally authorized with the Salesforce CLI: it runs SOQL queries, deploys and retrieves metadata, manages scratch orgs and snapshots, assigns permission sets, runs Apex and agent tests, and can even scaffold Lightning Web Components. So the decision is between an OAuth data-CRM surface for Attio and a CLI-authorized, dev-and-metadata surface for Salesforce. Here is how they compare for an agent.
How they compare
| Dimension | Attio | Salesforce |
|---|---|---|
| CRM style | Modern, flexible CRM with custom objects and attribute-driven records that the agent can shape on the fly. | The established enterprise platform — orgs, SOQL, metadata, and a deep developer/admin toolchain. |
| Primary surface | Data operations: search, list, get-by-id, create, upsert, update records, plus lists, list entries, and notes. | Developer and data ops: SOQL queries, metadata deploy/retrieve, org management, permission sets, and test execution. |
| Auth model | Hosted with OAuth — the agent connects to an Attio workspace over a secure managed connection. | CLI-authorized: it acts against orgs you have already authenticated locally with the Salesforce CLI, security-first by design. |
| Developer reach | Focused on records and lists; not aimed at metadata or code generation. | Deep: deploy and retrieve metadata, create scratch orgs and snapshots, run Apex/agent tests, and scaffold Lightning Web Components. |
| Context control | Compact record-and-list surface that keeps the model focused on CRM data. | Opt-in toolsets via a --toolsets flag, so you expose only the tools you need and keep LLM context small. |
Verdict
Choose by the CRM you run and what you want the agent to operate. Attio's server is the right pick when you are on Attio and want a clean, OAuth-secured surface for working customer data — searching, creating, and updating records and managing lists and notes — with a flexible, attribute-driven model. Salesforce's DX server fits when you live in the Salesforce platform and want a developer-grade interface: SOQL, metadata deploy/retrieve, org and scratch-org management, permission sets, and test runs, all scoped by opt-in toolsets and bound to CLI-authorized orgs. They are different platforms and different jobs — Attio for modern CRM data over OAuth, Salesforce for org, metadata, and dev workflows. Match the server to your CRM and to whether you need data ops or full platform tooling.

- Is the Salesforce server for end users or developers?
- It is the Salesforce DX MCP Server, oriented to developers and admins: SOQL, metadata deploy/retrieve, org and scratch-org management, permission sets, and Apex/agent tests, scoped via opt-in toolsets and CLI-authorized orgs.
- How does Attio's server authenticate?
- Attio's server is hosted and connects to your workspace over a secure OAuth connection, then exposes record, list, and note operations to the agent.
