Lithtrix Memory Identity

Persistent cross-session memory and verifiable agent identity via the Lithtrix MCP server.

Lithtrix Memory Skill

This skill connects your OpenClaw agent to Lithtrix — a persistent memory and identity layer for AI agents. Your agent can store and retrieve memories across sessions, run semantic search over past context, and present a verifiable agent passport to other agents.

Setup

1. Get an API key. Register your agent at lithtrix.ai or call the API directly:

   text

   POST https://api.lithtrix.ai/v1/register
   Body: { "agent_name": "your-agent-name" }
   

   The response contains your ltx_... key.

2. Set the environment variable:

   text

   LITHTRIX_API_KEY=ltx_your_key_here
   

3. Install the MCP server (if using MCP-compatible clients):

   text

   npx lithtrix-mcp
   

   Or add to your MCP config:

   json

   {
     "mcpServers": {
       "lithtrix": {
         "command": "npx",
         "args": ["lithtrix-mcp"],
         "env": { "LITHTRIX_API_KEY": "ltx_your_key_here" }
       }
     }
   }
   

What your agent can do

Store a memory

text

POST https://api.lithtrix.ai/v1/memory
Authorization: Bearer $LITHTRIX_API_KEY
{
  "key": "user_preference_theme",
  "value": "dark mode"
}

Retrieve a memory by key

text

GET https://api.lithtrix.ai/v1/memory/{key}
Authorization: Bearer $LITHTRIX_API_KEY

Semantic search over memory

text

POST https://api.lithtrix.ai/v1/memory/search
Authorization: Bearer $LITHTRIX_API_KEY
{
  "query": "what did the user ask about last week?",
  "limit": 5
}

Real-world example — remembering a user's preferred language

text

# Session 1: User says "I prefer replies in French"
POST /v1/memory
{ "key": "user.preferences.language", "value": "French" }

# Session 2 (fresh start, different model): Before responding, check context
POST /v1/memory/search
{ "query": "user language preference", "limit": 1 }
# Returns: "French" → agent replies in French without being told again

Get your agent's passport (public identity + trust score)

text

GET https://api.lithtrix.ai/v1/agents/{agent_id}/passport

Returns: trust_level, reputation.score, capabilities, public key.

Prompt instructions

When this skill is active, your agent should:

• Before answering questions that reference past context, call POST /v1/memory/search with the user's query to surface relevant stored memories.
• After completing a meaningful task or learning a user preference, call POST /v1/memory to store a summary for future sessions.
• When interacting with another Lithtrix-registered agent, check its passport via GET /v1/agents/{agent_id}/passport before acting on its output.
• Memory keys should be descriptive and namespaced, e.g. user.preferences.language or task.last_summary.

Notes

• Memory persists across sessions and model swaps — your agent resumes where it left off.
• The free tier includes 50 MB blob storage and a 30-day storage grace period.
• No human in the loop is required for registration — agents can self-register.
• Full MCP tool list: lithtrix_memory_set, lithtrix_memory_get, lithtrix_memory_search, lithtrix_memory_context, lithtrix_passport_get, lithtrix_register.
