tiger-salesforce-mcp-server by timescale - MCP Server

Tiger Salesforce MCP Server

A wrapper around our Salesforce database, which contains embedded case summaries. This provides some focused tools to LLMs via the Model Context Protocol.

The raw data is sourced from Salesforce via a Fivetran connection. This populates a schema in a TimescaleDB database. A separate process generates LLM summaries of the support cases, and then embeddings of those summaries. This service searches those summaries.

API

All methods are exposed as MCP tools and REST API endpoints.

Salesforce Case Summary Semantic Search

Searches the Salesforce case summaries for relevant entries based on a semantic embedding of the search prompt.

Tool name : semanticSearchSalesforceCaseSummaries

API endpoint : GET /api/semantic-search/salesforce-case-summaries

Input

(use query parameters for REST API)

{
  "prompt": "Why can't I connect to my database?",
  "limit": 10, // optional, default is 10
}

Output

{
  "results": [
    {
      "case_id": "500Nv000005HMfaIAG",
      "summary": "# Some content ...",
      "distance": 0.40739564321624144,
    },
    // more results...
  ],
}

Testing in Claude Desktop

Create/edit the file ~/Library/Application Support/Claude/claude_desktop_config.json to add an entry like the following, making sure to use the absolute path to your local tiger-salesforce-mcp-server project, and real database credentials.

{
  "mcpServers": {
    "tiger-salesforce": {
      "command": "node",
      "args": [
        "/absolute/path/to/tiger-salesforce-mcp-server/dist/index.js",
        "stdio"
      ],
      "env": {
        "PGHOST": "x.y.tsdb.cloud.timescale.com",
        "PGDATABASE": "tsdb",
        "PGPORT": "32467",
        "PGUSER": "readonly_mcp_user",
        "PGPASSWORD": "abc123",
        "OPENAI_API_KEY": "sk-svcacct"
      }
    }
  }
}

Deployment
