What the sources write about this name
| clipboard-mcp-server in namespace io.github | HTTP session mode: 'auto', 'stateful', or 'stateless'. 'auto' resolves to 'stateful'. This server defaults to 'stateless'. |
|---|---|
| libofcongress-mcp-server in namespace io.github | HTTP session mode: auto, stateful, or stateless. |
| met-museum-mcp-server in namespace io.github | HTTP session mode: auto, stateful, or stateless. This server explicitly sets stateless; the framework schema default is auto. |
| nhtsa-vehicle-safety-mcp-server in namespace io.github | HTTP session posture: 'auto', 'stateful', or 'stateless'. Overrides the stateless mode the server declares in code. |
| ntfy-mcp-server in namespace io.github | HTTP session model: 'auto', 'stateful', or 'stateless'. This server requires 'stateful' over HTTP — the consent prompt on destructive and outbound calls is a multi-round-trip request that a 2025-era HTTP client can only complete over a live session — so an HTTP start with 'stateless' is refused. 'auto' resolves to 'stateful'; stdio ignores the setting. |
| osv-advisory-mcp-server in namespace io.github | HTTP session mode. This server deploys stateless because its tools do not use multi-round input. |
| ourairports-mcp-server in namespace io.github | HTTP session mode. This read-only server uses stateless mode; available values are 'stateful', 'stateless', or 'auto'. |
| pokeapi-mcp-server in namespace io.github | Session mode to use: 'auto', 'stateful', or 'stateless'. The 'auto' schema default resolves to stateful. |
| pubchem-mcp-server in namespace io.github | HTTP session mode: stateless, stateful, or auto. Stateless is sufficient for PubChem; auto resolves to stateful. |
| shift-mcp-server in namespace io.github | Session handling for the HTTP transport: 'auto', 'stateful', or 'stateless'. |
