Tools
This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
SAIHM_ENDPOINT_URLOptional | SAIHM operator endpoint. Optional: defaults to the hosted service at https://saihm.net/mcp. |
SAIHM_SELF_JOINOptional | Self-join is ON by default: the saihm_join tool creates a non-custodial identity on this device and starts activating its free memory, which needs one browser sign-in; no master secret is needed. Set to '0' to suppress the tool. |
SAIHM_MASTER_SECRET_FILEOptional, secret | Path to a mode-600 file holding a 64+ hex-char master secret. Only needed if you opt out of self-join, are restoring an existing identity, or keep your key file outside SAIHM_HOME. Never transmitted. |
SAIHM_IDENTITYOptional, secret | An identity token written by export-identity: brings an existing SAIHM identity to this machine or a hosted agent environment without copying a key file. Set together with SAIHM_IDENTITY_PASSPHRASE; leave both unset to use this machine's own identity. |
SAIHM_IDENTITY_PASSPHRASEOptional, secret | The passphrase export-identity generated for SAIHM_IDENTITY. The two together are the identity: store it as a secret. |
SAIHM_TIEROptional | The plan this identity onboards with (FREE, PRO, PRO_FAST, ENTERPRISE, ENTERPRISE_FAST). Defaults to FREE while self-join is on (the default); set it for a paid plan, and with SAIHM_SELF_JOIN=0 for every plan, FREE included. An export-identity token carries its own, which a non-empty value here ove… |
SAIHM_PAYMENT_METHODOptional | The payment rail of a paid plan, e.g. stripe. Required for a paid SAIHM_TIER unless an export-identity token carries it. |
SAIHM_EPHEMERAL_HOMEOptional | Set it (e.g. 1) where the home directory is discarded at session end, or is a CI runner's home that later jobs can reach: the join then refuses to create a key, and SAIHM keeps no recall copy and no sign-in there. A copy or sign-in already written there stays until you delete it: the recall.* and s… |
SAIHM_HOMEOptional | Base dir for the self-join identity file ($SAIHM_HOME/free-identity.key, mode 600). Defaults to ~/.saihm. Give a full path: a relative one (a JSON config does not expand ~) is refused at start. Also the fallback state directory when SAIHM_STATE_DIR is unset. |
