Quick Start

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "salesforge": {
      "url": "https://mcp.salesforge.ai/mcp",
      "headers": {
        "X-Salesforge-Key": "YOUR_SALESFORGE_API_KEY",
        "X-Primeforge-Key": "YOUR_PRIMEFORGE_API_KEY",
        "X-Leadsforge-Key": "YOUR_LEADSFORGE_API_KEY",
        "X-Infraforge-Key": "YOUR_INFRAFORGE_API_KEY",
        "X-Warmforge-Key": "YOUR_WARMFORGE_API_KEY",
        "X-Mailforge-Key": "YOUR_MAILFORGE_API_KEY"
      }
    }
  }
}

Remove header lines for products you don't use. Restart Claude Desktop after saving.

Claude Code

claude mcp add salesforge \
  --transport streamable-http \
  --url https://mcp.salesforge.ai/mcp \
  --header "X-Salesforge-Key: YOUR_SALESFORGE_API_KEY" \
  --header "X-Primeforge-Key: YOUR_PRIMEFORGE_API_KEY" \
  --header "X-Leadsforge-Key: YOUR_LEADSFORGE_API_KEY" \
  --header "X-Infraforge-Key: YOUR_INFRAFORGE_API_KEY" \
  --header "X-Warmforge-Key: YOUR_WARMFORGE_API_KEY" \
  --header "X-Mailforge-Key: YOUR_MAILFORGE_API_KEY"

Cursor

Go to Settings > MCP and add a new server:

• Name: salesforge
• Type: streamable-http
• URL: https://mcp.salesforge.ai/mcp
• Headers: same as above

Getting API Keys

Authentication Headers

Multiple Accounts

If you manage multiple accounts (for example, different clients), add separate server entries:

{
  "mcpServers": {
    "salesforge-client-a": {
      "url": "https://mcp.salesforge.ai/mcp",
      "headers": {
        "Authorization": "Bearer CLIENT_A_KEY"
      }
    },
    "salesforge-client-b": {
      "url": "https://mcp.salesforge.ai/mcp",
      "headers": {
        "Authorization": "Bearer CLIENT_B_KEY"
      }
    }
  }
}

Each entry gets its own name and API keys. Your AI assistant sees tools from both and you specify which client to work with in your prompts.

Usage Examples

After setup, try asking your AI assistant:

• "List my Salesforge workspaces"
• "Show contacts tagged with 'enterprise' in workspace X"
• "Create a new sequence called 'Q2 Outreach'"
• "List leads in sequence 31086 and show the actions and conditions executed for a lead"
• "Show the parent sequences and enrolled contacts for subsequence 31086"
• "Enroll these contacts into the sequence"
• "Show my Primeforge domains"
• "Search Leadsforge for CTOs at SaaS companies in New York"
• "Pull the followers of the Salesforge LinkedIn page and find their emails"
• "Show me companies similar to salesforge.ai before I spend credits"
• "Find dentists within 10km of Amsterdam and get their owners"
• "Check my Infraforge credit balance"
• "Show warmup stats for my mailboxes"
• "Show which Warmforge mailboxes have 100% latest placement results"
• "List my Mailforge domains"
• "Check if example.com is available on Mailforge"

Asynchronous Email Validation

Start validation with start_email_validation. Before returning HTTP 201, Multichannel resolves and persists candidate membership. selected and skipped.duplicate are exact, supported counts: a non-empty selection returns status: pending, while an empty selection returns status: failed with failureCode: validation_scope_empty. The legacy strict option is omitted and deprecated. Retain the returned validationJobID and poll get_validation_results with roughly ten-second backoff. Continue until the status is terminal: completed, partially_completed, or failed. Inspect the polling response before enrolling contacts; it is authoritative for validation outcomes, terminal counts are authoritative, and a failed run must not be automatically resubmitted.

For enrollment, use preflight_enrollments with the completed or partially completed validationRunId, inspect the preflight, then use confirm_enrollment_preflight. To restrict candidates, provide non-empty validationStatuses; omitted or empty statuses mean no status restriction and all run candidates, including unvalidated contacts, are considered. Durable async runs evaluate non-empty statuses against the requested run's persisted results, while legacy completed runs evaluate them against current Salesforge status. A partial run does not automatically select only its successful subset.

Local HTTP MCP testing still proxies the deployed Multichannel API.

Rollout Dependency

Internal rollout order is binding: deploy the Multichannel async-validation contract before rolling out Forge MCP. Forge MCP must not reintroduce strict: false as a rollout workaround.

Self-Hosting

If you prefer to run your own instance:

npm install
npm run build
npm run start:http

The server listens on port 3000 by default. API keys are passed as headers per request, not as environment variables.

The HTTP endpoint uses stateless MCP POST requests. Standalone SSE streams are not offered: GET /mcp (and HEAD) returns 405 Method Not Allowed before allocating an MCP server. Per-request servers and transports are closed after handling, on failures, and when clients disconnect before the response finishes.

Diagnostic logging

Logging is enabled by default as JSON lines on stderr, suitable for container log collection. MCP stdio output remains reserved for protocol messages. HTTP requests, including /health, receive a generated X-Request-Id response header that correlates their request and upstream API logs.

For more detail, run LOG_LEVEL=debug npm run start:http. Invalid settings fall back to their defaults. Keep info or debug enabled during timeout investigations so request starts and process metrics are retained.

• http.request.started without a matching completed or aborted event indicates an unfinished request or a process that stopped before logging completion. http.request.slow is emitted while the request is still pending, including during body parsing.
• upstream.request.slow identifies a pending product API call; its timing includes reading and parsing the response. The parent requestId links it to the HTTP request, and upstreamRequestId separates multiple API calls.
• runtime.metrics shows whether event-loop delay, CPU, memory, or request counts increased around a timeout. A blocked event loop also delays logging; its stall becomes visible after it resumes.
• If a timed-out health check has no corresponding request-start event, check proxy/load-balancer logs and container restarts too. Requests may not have reached Express, or the process may have been unable to run. Logging alone cannot establish the root cause.

The structured logs omit headers, bodies, query strings, upstream paths, and error messages/stacks to avoid capturing API keys and customer data. Errors include type, code, and HTTP status where available. Existing Node/Express native diagnostics may still appear separately. HTTP routes other than /health and /mcp are labeled other.

LinkedIn replies

Use get_thread to read the conversation, then call reply_to_linkedin_thread with workspaceId, threadId, the sending LinkedIn accountId from the thread's LinkedIn messages, and message. LinkedIn-only threads do not require a mailbox ID. The tool calls the existing Salesforge public API and returns the created LinkedIn message.

Optional attachments accept filename, contentBase64, and optional contentType. For an attachment-only reply, pass an empty message and at least one attachment. The API validates supported file types and size limits.

Salesforge account and contact management

These tools require the public API additions in multichannel-api #1068 and salesforge-api #2795 (SF-9461). The matching API changes must be deployed before the tools can be used.

To attach a standalone LinkedIn account, use create_sender_profile with its linkedinAccountId. The account must belong to the workspace and must not already be attached to another sender profile.

The existing delete_sender_profile tool also deletes its attached LinkedIn account.

Salesforge mailbox and LinkedIn lifecycle

These tools require salesforge-api #2836 and multichannel-api #1111 (SF-10349), on top of the SF-9461 API additions above. The matching API changes must be deployed before the tools can be used.

There is no independent LinkedIn deletion tool or email disconnect tool. The existing delete_sender_profile tool also deletes its attached LinkedIn account.
