Best for
  • AI agents that need offline, low-latency, local memory.
  • Developers who want to avoid LLM calls during memory storage and recall.
  • Projects requiring persistent memory, knowledge graphs, or Hebbian learning.
  • Teams using Zenoh, ROS2, or robotic mission memory.
  • Teams already using ClickHouse who want AI assistants to access data directly.
  • Scenarios requiring fast, read-only data queries and schema exploration.
  • Teams that want precise control over which database operations an AI can perform, rather than open arbitrary SQL execution
  • Scenarios needing a unified MCP setup across multiple database engines
Not for
  • Users seeking a hosted cloud memory service or built-in multi-tenant authorization.
  • Applications expecting the server itself to perform LLM inference.
  • MCP clients operating without an available local backend.
  • Workflows that only need simple stateless text processing.
  • Scenarios requiring write access to the database without explicit opt-in.
  • Production environments with stringent security requirements that avoid default permission settings.
  • Lightweight cases that just want to run a few ad-hoc SQL queries without maintaining a tools.yaml config (a simpler single-database MCP may be a better fit)
Required permissions
  • Access to read and write Shodh-Memory's local memory data.
  • Permission to launch the npm package and local MCP server over stdio.
  • Network access to the address specified by SHODH_API_URL when using a remote backend.
  • SHODH_API_KEY when authentication is enabled; this variable is secret.
  • The tools can create, modify, and delete memories, todos, projects, reminders, and backups.
  • Requires read-only access to ClickHouse database (default).
  • Optional: write access via CLICKHOUSE_ALLOW_WRITE_ACCESS.
  • Optional: destructive operations via CLICKHOUSE_ALLOW_DROP.
  • Database credentials (username/password/connection string) are supplied via env vars or config
  • A tool's actual permission is whatever SQL statement is defined in tools.yaml — designed for least privilege, but misconfiguration can still over-expose access
Risks and side effects
  • Memories, todos, projects, and backups may contain sensitive information and persist locally.
  • forget, delete, purge, and backup_restore can cause data loss or overwrite data.
  • For remote deployments, the deployer must protect the API key and network exposure.
  • SHODH_USER_ID is a logical memory namespace, not an authorization tenant.
  • A local model is downloaded on first run, requiring local resources and model storage.
  • If write access is enabled, AI might make unintended modifications.
  • If DROP access is enabled, data deletion could occur accidentally.
  • Credentials may be exposed via environment variables.
  • If tools.yaml defines SQL statements that allow unconstrained writes or deletes, the AI could accidentally modify data
  • The prebuilt toolsets (--prebuilt) favor convenience and may expose broader query capability than a specific business actually needs — use a custom tools.yaml in production
