Salesforce MCP Server — Auto-Auth From Chrome

[![PyPI](https://img.shields.io/pypi/v/salesforce-mcp-auto-auth-chrome?label=pypi&color=blue)](https://pypi.org/project/salesforce-mcp-auto-auth-chrome/) [![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](LICENSE) [![Python 3.12+](https://img.shields.io/badge/python-3.12+-blue.svg)](https://www.python.org/downloads/) [![macOS](https://img.shields.io/badge/platform-macOS-lightgrey.svg)](#)

A local MCP server that exposes **14 Salesforce tools** (SOQL, SOSL, CRUD, Apex execute, tooling API, REST) inside Claude Desktop — and **auto-refreshes the session from your Chrome browser** so you never have to paste a token into your config again. Wraps [`mcp-salesforce-connector`](https://pypi.org/project/mcp-salesforce-connector/) on PyPI; runs as a stdio MCP launched per-org by Claude Desktop.

No connected app, no OAuth dance, no copy-pasting session ids — just stay logged into the org in Chrome.

       │
       └── one entry in claude_desktop_config.json per Salesforce org

The package is a thin Python shim around `mcp-salesforce-connector`. On every API call, it reads the `sid` cookie that Chrome stores when you're logged into Salesforce, and uses it as the `Authorization` header. That cookie value is identical to a Salesforce session id and is accepted as a Bearer token by the REST API. As long as you keep a Chrome tab open on the org, the session stays alive and Claude inherits the freshness.
