# MCP Tool Approval Change Card Compare two user-supplied local MCP `tools/list` JSON snapshots and create deterministic review cards. The tool reports advertised descriptor changes; it does not connect to a server, call listed tools, approve access, or prove that runtime behavior stayed the same. ## Requirements - Windows 11 with Python 3.11–3.14 - An MCP-compatible client that can launch a local stdio server - `MCP_LICENSE_KEY` from this MCP Marketplace purchase - Internet access for initial and periodic license verification The marketplace license check transmits only the buyer's license key and this product's public slug. Buyer snapshots, paths, and generated reports remain local. Apart from license verification, the package performs no network call or telemetry. The license SDK may use a previously verified local cache if its service is unavailable; revocation may therefore take effect later. ## Install ```powershell python -m pip install mcp-tool-approval-change-card-mcp==0.2.0 mcp-approval-card --json doctor ``` Place `MCP_LICENSE_KEY` in your MCP client's environment configuration. For a client using `mcpServers`: ```json { "mcpServers": { "mcp-tool-approval-card": { "command": "mcp-approval-card-mcp", "env": {"MCP_LICENSE_KEY": "PASTE_THE_KEY_FROM_YOUR_PURCHASE"} } } } ``` Launch the client with its working directory set to the folder containing the two buyer-authorized JSON snapshots. The one MCP tool is `make_change_cards(previous, current, output_directory)`. Use relative paths and a **new** output directory. Do not place real credentials in snapshots. For a first local check, save these two synthetic files in the client's working directory: `previous.json` ```json {"tools":[{"name":"lookup","description":"Search local index","inputSchema":{"type":"object"}}]} ``` `current.json` ```json {"tools":[{"name":"lookup","description":"Search updated local index","inputSchema":{"type":"object"}}]} ``` Then pass `previous.j…
