Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does

How to run each
Synapse Layer — Zero-Knowledge Memory As a local MCP server: PyPI package
claude mcp add --env "SYNAPSE_ENCRYPTION_KEY=<YOUR_SYNAPSE_ENCRYPTION_KEY>" --transport stdio synapse-secure-memory -- uvx synapse-layerRequires: SYNAPSE_ENCRYPTION_KEY (secret)
io.github.cdeust/hypermnesia-mcp As a local MCP server: PyPI package
claude mcp add --transport stdio hypermnesia-mcp -- uvx hypermnesia-mcpCommands built only from what the marketplaces declare; the full set for every client is on each card.
Tools each declares
Neither one's marketplaces publish a list of tools, so there is nothing to compare.
Settings each asks for
Only Synapse Layer — Zero-Knowledge Memory asks for
LOG_LEVELSYNAPSE_AGENT_IDSYNAPSE_ENCRYPTION_KEY (secret)SYNAPSE_PRIVACY_EPSILON
Only io.github.cdeust/hypermnesia-mcp asks for
CORTEX_MEMORY_AP_ENABLEDCORTEX_RUNTIMEDATABASE_URL
Settings as each marketplace publishes them. Asking for fewer is not better in itself.
