In-depth architectural comparison of the Being and Saihm MCP MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
Being
Knowledge & Memory · Remote HTTP/SSE
Quality: 45/100 (Fair) | Auth: API Key required
Saihm MCP
Knowledge & Memory · Local stdio
Quality: 63/100 (Good) | Auth: API Key required
Verdict Summary: Choose Being if you need specialized Knowledge & Memory tools running via a hosted cloud SSE transport. Choose Saihm MCP if your workspace requires Knowledge & Memory integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Being when:
You need dedicated capabilities in the Knowledge & Memory domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: API Key required (BYOK (Pay Provider Direct)).
You have access to required keys: SUPABASE_URL, SUPABASE_SERVICE_ROLE_KEY, ENCRYPTION_KEY.
Primary tools included: Structured SOUL personality definitions, Scene-based episodic memory with decay and consolidation, Patrol background reflection and memory processing.
Personality Runtime for AI agents — persistent memory, identity (SOUL), and relationships that travel across Claude, OpenClaw, Mistral, and any MCP client.
Sovereign, encrypted, persistent memory for AI agents. Eight MCP tools — remember, recall, forget (GDPR Art. 17 erasure), share. Anchored on COTI V2 mainnet. Apache-2.0. Install: npx -y @saihm/mcp-server.
Being is categorized under Knowledge & Memory and uses a remote streaming HTTP/SSE transport. In contrast, Saihm MCP belongs to Knowledge & Memory using local stdio subprocess. Select Being when you need capabilities focused on knowledge & memory and Saihm MCP when you require tools for knowledge & memory.
Store information in SAIHM persistent encrypted memory. Use this when a fact, decision, or piece of context should outlive the current session. Returns the cell id that saihm_forget takes.
saihm_recall
Retrieve memories from the SAIHM encrypted store; the operator decrypts and returns plaintext, and this client holds no keys. Use at the start of a session, or whenever past context is needed. Pass a keyword to filter, or leave empty to load all.
saihm_forget
Cryptographically erase one memory by its cell id (GDPR Art. 17). Destroying the key makes the content unreadable to everyone, the operator included. Irreversible: use it when erasure is the intent, not to tidy a working set.
saihm_status
Show the current SAIHM session: agent identity, tier, the prs and bfsi scores, storage by tier, and sharing state, as far as the operator reports them — a non-custodial operator cannot see stored-byte totals. Use it to check the agent identity, custody mode, and what the operator reports about storage and sharing.
saihm_share
Grant other agents access to specific memory shards. Set type to 'temporary', 'permanent' or 'syndicate', and scope to 'read', 'write' or 'readwrite'. Grantees are hex agent-id hashes, not names, and shardIds lists exactly what is shared: nothing outside it is exposed, and sharing does not copy the memory.
saihm_revoke_share
Revoke a sharing contract by its contractId, withdrawing access granted with saihm_share. It applies to future reads and cannot retract what a grantee has already read. Use it to end access; the memory itself remains, and saihm_forget is what erases.
saihm_governance_propose
Open a protocol governance proposal: set scope to 'emission_param' or 'protocol_upgrade', and for 'emission_param' also pass paramKey and proposedValue. Protocol governance is not enabled by default. The call is forwarded to the operator endpoint you configured, so expect an error rather than an open vote unless that operator has turned governance on. Where it is enabled it returns a hex proposalId that saihm_governance_vote takes, and it starts a vote rather than changing a setting.
saihm_governance_vote
Cast a vote on an open protocol governance proposal by its proposalId, with approve set to true to approve or false to reject. Protocol governance is not enabled by default. The call is forwarded to the operator endpoint you configured, so expect an error rather than a recorded vote unless that operator has turned governance on. Where it is enabled, vote weight derives from the governance-token balance held at the proposal snapshot epoch, not the balance at the time of voting.
