Summit53 Revenue Engine

Summit53 MCP Server

Bring Summit53's Revenue Engine into the AI workflows your team already uses.

This package connects MCP-compatible assistants to Summit53's hosted Revenue Engine. Assistants can help diagnose pipeline and forecast gaps, decide the next best action, execute permitted workflows, and preserve value evidence around the Figure-Eight revenue loop — from acquisition through expansion and back into acquisition.

[npm version] [MCP Compatible] [License]

Using Claude or Codex? Install the Summit53 plugin from github.com/Summit53/skills instead. It connects the hosted Summit53 server directly (no local package) and adds guided Summit53 skills for forecast, deal, renewal, coaching, territory and board workflows.

In claude.ai, Claude Desktop or Cowork, add the marketplace https://github.com/Summit53/skills under Customize › Plugins › Add. This repository is not a plugin marketplace.

Quick start

Most clients, including claude.ai, Claude Desktop, Claude Code, Codex and Cursor, can connect to the hosted server directly at https://api.summit53.io/mcp and sign in with OAuth:

claude mcp add --transport http summit53 https://api.summit53.io/mcpcodex mcp add summit53 --url https://api.summit53.io/mcp

This package is a local stdio bridge for clients that only support command-based servers:

{  "mcpServers": {    "summit53": {      "command": "npx",      "args": ["-y", "@summit53/mcp-server"]    }  }}

On first use, your browser opens the Summit53 OAuth flow. Sign in, review the requested access, and authorize the client. Tokens are cached by the local MCP bridge and refreshed automatically.

For a web client that supports custom remote MCP connections, add:

• Name: Summit53
• URL: https://api.summit53.io/mcp

Client availability and labels vary by plan and workspace. Use the custom server URL instead of relying on a public app-directory listing.

See the MCP setup guide for client-specific instructions.

What the Revenue Engine enables

Ask in natural language to:

• diagnose pipeline risk, deal drag, forecast confidence, gaps, and capacity;
• prepare opportunity strategy, account reviews, weekly action plans, and coaching;
• research accounts and inspect notes, activity, outreach, value impact, and methodology knowledge;
• write permitted notes, outreach updates, value evidence, and coaching outcomes;
• track long-running work through a durable job lifecycle.

The current release gate freezes 75 externally published functions across 15 categories. That count is a compatibility fact, not the product proposition. Tool visibility depends on the client's granted scopes and the user's Summit53 organization permissions; call list_available_tools to discover the surface available in the current session.

The exact machine-readable surface is maintained in tool-catalog.json. The registry-compatible connection manifest is server.json. The tool reference explains inputs, outputs, access requirements, and async behavior.

Authentication and permissions

Interactive connections use OAuth 2.1-style authorization with PKCE. Access tokens last one hour; rotating refresh tokens last seven days. Access can be revoked from /admin/integrations/mcp in Summit53.

The published scope set is:

• read: crm:read, pipeline:read, revenue:read, actions:read, jobs:read;
• write and operations: crm:write, outreach:write, outreach:send, coaching:write, value:write, automation:manage, jobs:manage.

Business write tools always require their explicit write scopes. Job lifecycle tools always enforce jobs:read or jobs:manage. Read-scope enforcement for the remaining catalogue is being rolled out behind a production gate. Summit53's organization, ownership, and role permissions remain authoritative in every case.

Some approved service integrations can use scoped static API keys, but API keys are not part of the normal interactive setup. A scope authorizes an operation; it does not itself prove human approval. Broader high-risk write workflows remain gated until portable approval controls are available.

Async jobs

Long-running tools return a durable job response rather than asking the client to hold an HTTP request open. Use:

• get_job to inspect status and results;
• list_jobs to find recent work;
• cancel_job to request cancellation when the job is still cancellable.

Job records are retained for 30 days. Every published function uses the same versioned response envelope so clients can handle success, partial results, queued work, and errors consistently.

Architecture

• Transport: Streamable HTTP through the hosted Summit53 service
• Endpoint: https://api.summit53.io/mcp
• Tenant boundaries: Summit53 authentication and application permissions
• Rate limiting and caching: enforced by the hosted service, with tool-specific policies
• Metrics: usage and errors tracked per organization and tool
