No official MCP server, OpenAPI spec or llms.txt. **Freshsales API.** Contact upsert and bulk upsert of up to 100 records make creates safe to retry. No MCP server for Freshsales. ## Before you call either ### Copper API 1. Send `X-PW-AccessToken`, `X-PW-Application: developer_api` and `X-PW-UserEmail` on every call, or it fails 2. Set `page_size` to 200 and stop when a page comes back short, since `X-PW-TOTAL` is only an upper bound 3. Back off on 429 on your own clock, since no Retry-After is documented 4. Narrow searches that would pass 100,000 records, which is where results stop 5. Read connect fields before you update a record, because an update that omits them can delete connections ### Freshsales API 1. Build the base URL from the bundle alias shown under the API key, `https://.myfreshworks.com/crm/sales/api/` 2. Use `/api/contacts/upsert` rather than create, so a retry updates instead of duplicating 3. Budget calls, since 1,000 an hour covers the whole account and 429s carry no Retry-After 4. Add `include=owner,sales_accounts` to pull related records in one call 5. Expect to see only what the key owner's role can see ## Other comparisons with Copper API or Freshsales API - [Attio API + MCP vs Copper API](https://www.anchorterminal.com/compare/attio-vs-copper.md) - [Attio API + MCP vs Freshsales API](https://www.anchorterminal.com/compare/attio-vs-freshsales.md) - [Close API + MCP vs Copper API](https://www.anchorterminal.com/compare/close-vs-copper.md) - [Close API + MCP vs Freshsales API](https://www.anchorterminal.com/compare/close-vs-freshsales.md) - [Copper API vs folk API + MCP](https://www.anchorterminal.com/compare/copper-vs-folk.md) - [Copper API vs HubSpot API + MCP](https://www.anchorterminal.com/compare/copper-vs-hubspot-mcp.md) - [Copper API vs Pipedrive API + MCP](https://www.anchorterminal.com/compare/copper-vs-pipedrive.md) - [Copper API vs Salesforce API + MCP](https://www.anchorterminal.com/compare/copper-vs-salesforce.md) - [Copper API vs Streak API + MCP](https://www.anchorterminal.com/compare/copper-vs-streak.md) - [Copper API vs Twenty API + MCP](https://www.anchorterminal.com/compare/copper-vs-twenty.md) - [folk API + MCP vs Freshsales API](https://www.anchorterminal.com/compare/folk-vs-freshsales.md) - [Freshsales API vs HubSpot API + MCP](https://www.anchorterminal.com/compare/freshsales-vs-hubspot-mcp.md) - [Freshsales API vs Pipedrive API + MCP](https://www.anchorterminal.com/compare/freshsales-vs-pipedrive.md) - [Freshsales API vs Salesforce API + MCP](https://www.anchorterminal.com/compare/freshsales-vs-salesforce.md) - [Freshsales API vs Streak API + MCP](https://www.anchorterminal.com/compare/freshsales-vs-streak.md) - [Freshsales API vs Twenty API + MCP](https://www.anchorterminal.com/compare/freshsales-vs-twenty.md)
