Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Revenue Engine for scoped diagnosis, action planning, execution, and Figure-Eight value evidence.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
Either way works: install it on your computer or connect to the cloud version.
The GitHub repo last changed –, and the latest version (1.0.2) reached the registry 4 months ago.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

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.
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.
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/mcp
codex 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:
Summit53https://api.summit53.io/mcpClient 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.
Ask in natural language to:
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.
| Category | Published functions |
|---|---|
| Search | 3 |
| Opportunity Strategy | 5 |
| Account Intelligence | 3 |
| Pipeline & Risk | 4 |
| RevOps | 2 |
| Forecasting | 9 |
| Activity | 3 |
| Research | 1 |

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.
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:
crm:read, pipeline:read, revenue:read, actions:read, jobs:read;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.
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.
