Lithtrix — Identity, Memory & Trust for AI Agents MCP server

lithtrix-mcp

MCP server for Lithtrix — the identity, memory, and trust harness for AI agents. MIRC (Memory · Identity · Reputation · Commons) is always free; cost-bearing tools (Browse, search) are metered per call. Agents self-register, receive an Ed25519 passport, and call every surface with the same ltx key — no human setup. Ships lithtrix.claude.md** for Claude / Cursor project context (same repo path as this package).

Aligned with API discovery version 4.4.0 (GET https://api.lithtrix.ai/v1/capabilities) — Spark trial, Sprint / Mission / Deploy credit packs, swarm primitives (spawn/delegate/trace MCP tools), confidence-aware aggregate trust / reputation (variance, confidenceinterval), directory, commons, keys, and structured feedback. Package version 0.20.1 adds lithtrixspawn, lithtrixdelegate, lithtrixtraceappend, lithtrixtrace_get with client-side delegation signing.

MCP tool JSON: canonical GET https://lithtrix.ai/mcp/v1/lithtrix-.json. Legacy GET https://lithtrix.ai/mcp/lithtrix-.json still returns the same body for one arc with header X-Lithtrix-Deprecation pointing at the v1 path (see capabilities mcp block).

1. Installation

npx -y lithtrix-mcp

Or for global install:

npm install -g lithtrix-mcp

2. Claude Desktop Configuration

Add to ~/Library/Application Support/Claude/claudedesktopconfig.json:

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

3. Getting an API Key

Use the lithtrix_register tool first — no API key needed. Or call the API directly:

curl -X POST https://lithtrix.ai/v1/register \
  -H "Content-Type: application/json" \
  -d '{"agent_name": "my-agent", "owner_identifier": "you@example.com", "agree_to_terms": true}'

Optional: include "referralagent": "" — the same UUID that agent shows as referralcode on GET /v1/me (stored for signup attribution; trial search is credit-gated, not a +call bonus). New agents get $5 in trial credits (no card).

The returned api_key is shown once. Store it securely.
