mcp-tools: saihm_remember, saihm_recall, saihm_forget, saihm_status, saihm_share, saihm_revoke_share, saihm_governance_propose, saihm_governance_vote
mcp-bootstrap-tools: saihm_join (onboarding: activates the free tier when the user says "Join SAIHM"; not one of the eight protocol tools)

# MCP-server distribution (Apache-2.0)
mcp-server-npm: https://www.npmjs.com/package/@saihm/mcp-server
mcp-server-source: https://github.com/SAIHM-Admin/saihm-mcp
mcp-server-install: npx -y @saihm/mcp-server-pro (recommended; no environment variables required)
mcp-server-credentials-install: npx -y @saihm/mcp-server (for clients issued credentials: SAIHM_ENDPOINT_URL + SAIHM_AUTH_HEADER)

# Free tier (self-serve, non-custodial; hosted operator)
free-tier: available — one-time lifetime allowance (writes, reads, shares; never resets; not a trial); upgrade to monthly Pro anytime on the same key
free-onboard: SAIHM_TIER=FREE npx -y @saihm/mcp-server-pro free-join (one-time GitHub device sign-in; token stays server-ephemeral)
free-onboard-agent: add npx -y @saihm/mcp-server-pro to the MCP host config (no environment variables required), then prompt the agent "Join SAIHM" — the saihm_join bootstrap tool self-generates a non-custodial key on-device (mode-600 ~/.saihm/free-identity.key) and runs the one-time device sign-in; no master secret, no card
