Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start: SYMFONY_MCP_DYNAMIC_TOOLS (Progressive tool discovery. Left on, tools/list advertises five discovery meta-tools and the rest become callable once a category is activated (~828 tokens on connect). Set to false to advertise all 1,677 up front (~154,000).), SYMFONY_MCP_TOKEN_BUDGET (Token ceiling for the schemas a session may have active at once.), SYMFONY_MCP_ALLOWED_PATHS (Colon-separated allowlist of directories the server may read. Any app_path outside them is refused.), SYMFONY_MCP_SESSION_SECRET (Enables session-token authentication. Unset, authentication is off.), SYMFONY_MCP_SESSION_TOKEN (Client-side token, required only once SYMFONY_MCP_SESSION_SECRET is set.), SYMFONY_MCP_AUDIT (Encrypted audit log of every tool call.), SYMFONY_MCP_DLP (Scan every result for credentials before returning it. Turning this off is reported as CRITICAL by the startup audit.). The author declared them in the registry entry; get the values from the project itself.
