Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
List workflows and variables; create sessions and list session documents in Gavel.
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.

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
gavel_list_workflowsList the names of all Gavel workflows on the account. API: GET /api/playground?folder=questions.
gavel_get_workflow_variablesGet the variable schema of one workflow: each variable name, data type, input type, label, options and whether it is required. Use it to learn what data gavel_create_session accepts. API: GET /officeaddin?pgtypes= .yml.
gavel_create_sessionWRITE: create a new session of a workflow with pre-filled variables. It does not send or sign anything. Each call creates one more session. Returns session_id and a continuation_url. If all variables are given, the URL opens the document download page; else the user answers only
gavel_list_session_documentsList the documents of a completed workflow session: name, format (docx or pdf), type, source template and download URL. This tool returns metadata only. The download URL needs the X-Api-Key header. API: GET /api/documate/v1/data-manager/workflows/{name}/session/{id}/documents.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 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.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (1.2.3) reached the registry yesterday.
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.

Use your Gavel account from Claude, Cursor, or any MCP client. List workflows and their variables, create workflow sessions and list the documents of a session. Hosted, no local install: connect with your own credentials.

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Gavel credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/gavel/
On first connect you provide your Gavel subdomain and a Gavel API key (Gavel → Settings → API Keys). You need a Builder or Admin role and a plan with API access. The server validates it and stores it per user. No keys go in config files.
