Salesforce Metadata MCP Server

salesforce-metadata-mcp

The only Salesforce MCP server that builds Agentforce agents, OmniStudio components, and DevOps Center pipelines — alongside a complete daily developer loop (schema describe, Apex read, debug logs) and 228 tools total for building, configuring, and automating Salesforce orgs directly from Claude or any MCP client.

---

Quick Start

npx -y salesforce-metadata-mcp

Or install globally:

npm install -g salesforce-metadata-mcp
salesforce-metadata-mcp

---

Configuration (Claude Desktop / Claude Code)

Add to your MCP configuration (claude_desktop_config.json or .claude/settings.json):

{
  "mcpServers": {
    "salesforce": {
      "command": "npx",
      "args": ["salesforce-metadata-mcp"],
      "env": {
        "SF_INSTANCE_URL": "https://your-org.salesforce.com",
        "SF_ACCESS_TOKEN": "your_access_token"
      }
    }
  }
}

See SETUP.md for all authentication methods and detailed setup instructions.

One-click install (Claude Desktop)

Download salesforce-metadata-mcp-<version>.mcpb from the latest release, then drag it into Claude Desktop → Settings → Extensions. It prompts for your org URL and credentials — no JSON editing.

The bundle resolves the server from npm at launch rather than embedding a copy, so it always runs the current published version and never needs re-downloading after an upgrade.

Docker

docker build -t salesforce-metadata-mcp .
docker run -i --rm \
  -e SF_INSTANCE_URL="https://your-org.my.salesforce.com" \
  -e SF_ACCESS_TOKEN="your_access_token" \
  salesforce-metadata-mcp

The image builds from source, runs as a non-root user, and ships production dependencies only. Because this server speaks MCP over stdio, -i is required — the container is driven by its client, not run as a background service. SF_ALIAS will not work in a container: the Salesforce CLI's login flow needs a browser, so use token, JWT, refresh-token, or client-credentials variables instead.

Toolsets — loading 228 tools without burning your context

All 228 tools are always available. Most are not loaded into the model's context until something asks for them.

Listing every tool up front costs roughly 98,000 tokens — about half a 200k context window, spent before you type anything, whether or not the session ever touches OmniStudio or DevOps Center. A 228-candidate tool list also makes the model measurably worse at picking the right tool. So the server starts with a small core loaded and pulls in the rest on demand:

The default covers what nearly every session needs: describe/list objects, SOQL query, deploy/retrieve/delete metadata, deploy status, and core schema creation (objects, fields, formula fields, picklist values, validation rules, approval processes).

Three tools are always present and make everything else reachable:

• sf_find_tool — search all 228 tools by name and load whatever contains the matches, in one call. Ask for "create an omniscript" and it finds the tools, loads omnistudio, and they are callable immediately. This is usually all you or the model needs.
• sf_load_toolset — load named toolsets explicitly.
• sf_list_toolsets — browse all toolsets, their tool counts, and what is loaded.

In practice you don't manage this by hand: ask for what you want, and the model loads what it needs.

To restore the previous behaviour of loading everything at startup, set SF_TOOLSETS=all. To start with only the three meta-tools, set SF_TOOLSETS=none. To pick your own core, pass a list:

{ "env": { "SF_TOOLSETS": "metadata,objects,automation,security" } }

Available toolsets: core, metadata, objects, data, flows, automation, security, apex, lwc, ui, pages, actions, agentforce, omnistudio, omnichannel, devops, deployment, integrations, identity, reports, experience, admin, monitoring, audit, einstein, knowledge, cpq, sandbox, streaming, visualforce, aura, comms, mcp, i18n.

Flow tools live in their own flows toolset because sf_create_flow carries the full Flow element schema — 15,266 bytes (~4,126 tokens) on its own, the largest tool definition in the server. Keeping it out of the default means sessions that never build a Flow never pay for it, while sessions that do still get the complete validated schema.

Example Prompts

Build a complete object:

"Create a custom object called Project__c with fields: Name (text), Status__c (picklist: Planning/Active/Complete), Budget__c (currency), then add a validation rule requiring Budget when Status is Active."

Deploy Apex:

"Create an Apex class called OpportunityService that queries all Opps with Amount > 100000. Then create a test class for it."

Create a flow:

"Create a record-triggered flow on Opportunity that fires after save when Stage = Closed Won. Send an email alert to the owner and create a follow-up Task due in 30 days."

Set up an LWC:

"Create a Lightning Web Component called accountSummary that displays account name, industry, and annual revenue. Make it available on Record Pages."

Agentforce setup:

"Create an Agentforce agent called SalesAssistant. Then create a GetOrders action linked to the Get_Account_Orders flow. Then create an OrderManagement topic with actions: [GetOrders]. Finally wire SalesAssistant to topic OrderManagement."
