Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Notarize, e-sign, and verify identity with the Proof API. Unofficial; not affiliated with Proof.
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.

An unofficial command-line interface for interacting with the Proof API. The Proof CLI provides access to Business, Real Estate, and SCIM APIs through a unified interface.
# macOS / Linux: downloads the latest release for your OS and CPU into the current directory
curl -sL "https://github.com/tsarlewey/proof-cli/releases/latest/download/proof_$(uname -s | tr A-Z a-z)_$(uname -m | sed 's/x86_64/amd64/;s/aarch64/arm64/').tar.gz" | tar xz proof ./proof version

git clone https://github.com/tsarlewey/proof-cli.git
cd proof-cli go build -o proof ./proof --help
Claude Code plugin (bundles a usage skill and the MCP server; needs proof on your PATH):
/plugin marketplace add tsarlewey/proof-cli
/plugin install proof@proof
MCP server for any MCP client. proof mcp exposes every API command as a tool over stdio, annotated read-only or destructive:
claude mcp add proof -- proof mcp # Claude Code
claude mcp add proof -- proof mcp --read-only # only tools that don't change anything
For other clients, run the command proof mcp. It reads credentials the same way as the CLI (PROOF_API_KEY or proof config).
Docker, with nothing installed locally. The image runs proof mcp and is listed in the MCP Registry as io.github.tsarlewey/proof-cli:
docker run -i --rm -e PROOF_API_KEY -e PROOF_API_ENDPOINT=https://api.fairfax.proof.com ghcr.io/tsarlewey/proof-cli
Arguments after the image name go to proof mcp, e.g. --read-only. PROOF_API_ENDPOINT overrides the configured endpoint in any mode; leave it unset for production.
Agents using the shell can follow skills/proof/SKILL.md. Output is JSON (--pretty=false for compact), and API errors exit 1 with the response body on stderr. Point at the sandbox while testing: proof config set-endpoint https://api.fairfax.proof.com.
Before using the CLI, you need to configure your API key:
# Set your API key
proof config set-api-key YOUR_API_KEY
export PROOF_API_KEY=YOUR_API_KEY
proof config get
In order to get an API Key, you'll need an account with API Usage. You can get that here - https://www.proof.com/pricing#business
After your account is created and upgrade use https://dev.proof.com/docs/api-keys to setup your key.
The CLI supports OAuth 2.0 client credentials flow for secure API authentication:
# Configure OAuth credentials
proof config set-oauth [--scope="read write"]
proof config test-oauth
proof config disable-oauth
OAuth tokens are automatically refreshed before expiration (5-minute buffer).
The CLI is organized into three main API groups:
business - Business API operations (transactions, documents, webhooks, notaries, etc.)real-estate - Real Estate/Mortgage API operationsscim - SCIM API operations for user management# Get help for any command
proof --help proof business --help proof real-estate --help proof scim --help
The Business API provides comprehensive transaction and document management capabilities.
