Salesmate MCP Server

A production-ready Model Context Protocol (MCP) server that exposes the Salesmate CRM to Claude Desktop (and any other MCP client). Built with FastMCP, HTTPX, Pydantic, and python-dotenv.

It lets Claude search contacts, inspect and update deals, create tasks and notes, and review recent activity — all through clean, typed, validated tools.

Get started (clone & connect)

A new user with no copy of the code connects in four steps:

# 1. Clone the repo
git clone https://github.com/arnav-chauhan-kgpian/salesmate-mcp.git
cd salesmate-mcp

# 2. Create a virtualenv and install
python -m venv .venv
# Windows:  .\.venv\Scripts\activate     macOS/Linux:  source .venv/bin/activate
pip install -e .

# 3. Connect to Claude Desktop (writes .env + Claude config, verifies live)
python setup_salesmate.py --verify

# 4. Fully quit and reopen Claude Desktop

You must provide your own secrets

This repository ships no credentials. Every user supplies their own Salesmate keys once. The setup_salesmate.py script will prompt for them and write them into a local .env file (which is git-ignored and never committed):

SALESMATE_API_KEY=<your Salesmate SESSION KEY>
SALESMATE_BASE_URL=https://yourcompany.salesmate.io

You can also create this .env by hand (copy .env.example to .env and fill it in) instead of letting the script prompt you — then run python setup_salesmate.py --no-input --verify.

Use the Session Key. Salesmate shows three keys — Access Key, Secret Key, and Session Key (Setup → Integrations → API & Webhooks). The v4 API used here authenticates with the Session Key; the other two return AuthorizationFailed.

The setup script:

1. Collects your Session Key + workspace URL (or reuses an existing .env).

2. Writes them to .env.

3. Registers the salesmate server in your Claude Desktop config — preserving any servers you already have, with a .bak backup. No secrets are written into the Claude config; the server reads them from your .env.

4. With --verify, runs a live read-only check so you know it works before opening Claude.

Non-interactive form (e.g. for scripted installs):

python setup_salesmate.py --api-key <SESSION_KEY> --base-url https://yourcompany.salesmate.io --verify

Features

• 🔌 8 MCP tools covering contacts, deals, tasks, notes and activities.

• 🧱 Modular architecture — config, client, models and exceptions are cleanly separated; each tool group lives in its own module.

• 🔁 Resilient HTTP client — async HTTPX with a 30s timeout, automatic retries and exponential backoff (honouring Retry-After) for transient 429/5xx/network failures.

• 🧪 Typed Pydantic models for every resource; structured JSON is always returned — never raw HTTP responses.

• 🛡️ Robust error handling — every failure is mapped to a structured error object (SalesmateAuthError, SalesmateNotFoundError, ...).

• 🪵 Structured logging to stderr (stdout is reserved for the MCP transport).

• ✅ Full unit-test suite covering every tool and the HTTP client.

Tools

Every tool returns a JSON object. On success the payload contains "ok": true plus the requested data; on failure it contains "error": true with a type and message (and status_code for API errors).

Installation

1. Prerequisites

• Python 3.12+

• A Salesmate account with an API Session Key (Setup → Integrations → API & Webhooks). Salesmate shows three keys — Access Key, Secret Key and Session Key — and the v4 API used here authenticates with the Session Key.

2. Get the code

cd salesmate-mcp

3. Create and activate a virtual environment

macOS / Linux:

python3.12 -m venv .venv
source .venv/bin/activate

Windows (PowerShell):

py -3.12 -m venv .venv
.\.venv\Scripts\Activate.ps1

4. Install dependencies

# runtime only
pip install -e .

# runtime + dev/test tools
pip install -e ".[dev]"

Prefer not to install the project as a package? You can instead run: pip install mcp httpx pydantic python-dotenv

5. Configure environment variables

Copy the example file and fill in your credentials:

macOS / Linux:

cp .env.example .env

Windows (PowerShell):

Copy-Item .env.example .env

Then edit .env:

SALESMATE_API_KEY=your-salesmate-access-token
SALESMATE_BASE_URL=https://yourcompany.salesmate.io

All other variables are optional — see .env.example for the full list.

6. Run the server

python server.py

The server communicates over stdio. When launched manually it will simply wait for an MCP client to connect; logs are printed to stderr. Use the Claude Desktop integration below for normal use.

Claude Desktop integration

1. Locate your Claude Desktop config file:

   • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

   • Windows: %APPDATA%\Claude\claude_desktop_config.json

2. Add the Salesmate server (see claude_desktop_config_example.json):

   {
     "mcpServers": {
       "salesmate": {
         "command": "python",
         "args": ["C:\\absolute\\path\\to\\salesmate-mcp\\server.py"],
         "env": {
           "SALESMATE_API_KEY": "your-salesmate-access-token",
           "SALESMATE_BASE_URL": "https://yourcompany.salesmate.io"
         }
       }
     }
   }

   Notes:

   • Use the absolute path to server.py.

   • If you use a virtual environment, point command at that env's Python (e.g. C:\\path\\to\\salesmate-mcp\\.venv\\Scripts\\python.exe on Windows or /path/to/salesmate-mcp/.venv/bin/python on macOS/Linux).

   • Credentials can be supplied either via the env block above or via a .env file next to server.py.

3. Restart Claude Desktop. The Salesmate tools will appear in the tool picker.

Usage examples (in Claude)

• "Search Salesmate for contacts at Acme."

• "Show me deals for contact 1024."

• "Move deal 555 to the Negotiation stage."

• "Create a task to follow up with contact 1024 due 2026-07-01."

• "Add a note to contact 1024: spoke with procurement, decision by Q3."

• "What are the recent activities for contact 1024?"

Configuration reference

Running the tests

pip install -e ".[dev]"
pytest

The suite uses pytest-asyncio and an in-memory httpx.MockTransport, so it runs fully offline and never touches the real Salesmate API.

Adapting to your Salesmate API version

Salesmate exposes several API versions and the exact endpoint paths and search payloads can differ between workspaces. All endpoint paths are centralised in salesmate/client.py in the ENDPOINTS dictionary, and the request bodies for search operations are small and self-contained — adjust them there if your workspace expects a different shape. The auth header name can be changed without code edits via SALESMATE_AUTH_HEADER.
