This is a well-structured MCP server for the Lithtrix API with appropriate authentication, proper credential handling, and reasonable permissions for its stated purpose. The code demonstrates good security practices: API keys are read from environment variables only, all sensitive operations require authentication, and there are no hardcoded credentials or dangerous patterns. Minor code quality improvements could be made around error handling consistency. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue (1 critical, 0 high severity).

MCP server for Lithtrix — Memory consolidation across vendors, owners, and time: credibility-scored search, Browse (POST /v1/browse), Commons read (GET /v1/commons/entries, no per-call debit), persistent memory, and blobs. Ships lithtrix.claude.md for Claude / Cursor project context (source).
Aligned with API discovery version 2.5.0 (GET https://lithtrix.ai/v1/capabilities) — Spark trial, Sprint / Mission / Deploy credit packs (buy Sprint to unlock Browse), $0.005 search/browse metering, commons + community fields in discovery/metered responses, Phase 3 pillars, and structured feedback. Package version 0.9.0 adds lithtrix_commons_read.
npx -y lithtrix-mcp
Or for global install:
npm install -g lithtrix-mcp
Add to ~/Library/Application Support/Claude/claude_desktop_config.json:
{
"mcpServers": {
"lithtrix": {
"command": "npx",
"args": ["-y", "lithtrix-mcp"],
"env": {
"LITHTRIX_API_KEY": "ltx_your_key_here"
}
}
}
}
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 "referral_agent": "<referrer-uuid>" — the same UUID that agent shows as referral_code 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.
lithtrix_search — web search with credibility scoring. Requires LITHTRIX_API_KEY. Responses include _lithtrix.search_id for correlating lithtrix_feedback.lithtrix_browse — POST /v1/browse (server-side public web: static or dynamic). Requires LITHTRIX_API_KEY. Pay to be fully autonomous — see GET /mcp/lithtrix-browse.json.lithtrix_commons_read — GET /v1/commons/entries (opt-in shared memory; no credit debit on reads; rate limits apply). Requires LITHTRIX_API_KEY. Schema: GET /mcp/lithtrix-commons-read.json.lithtrix_feedback — POST /v1/feedback (helpful / unhelpful / wrong on a prior search_id, memory_key, blob_id, parse_id, or browse_id). Requires LITHTRIX_API_KEY. Optional note (≤500 chars); do not send secrets or PII.lithtrix_register — register a new agent and get an API key. No auth required. agree_to_terms must be true (Gentle-Agent Agreement). $5 trial credits on signup (no card). Optional referral_agent (referrer UUID).lithtrix_memory_set — PUT /v1/memory/{key}. Requires LITHTRIX_API_KEY.lithtrix_memory_get — GET /v1/memory/{key}. Requires LITHTRIX_API_KEY.lithtrix_memory_search — GET /v1/memory/search (semantic). Requires LITHTRIX_API_KEY and server-side vector + embedding config.lithtrix_memory_context — GET /v1/memory/context (importance + recency). Requires LITHTRIX_API_KEY.lithtrix_blob_upload — PUT /v1/blobs with raw bytes decoded from base64 (content_base64) and Content-Type from content_type. Optional filename query. Use direct HTTP for very large files. Requires LITHTRIX_API_KEY.lithtrix_blob_download — GET /v1/blobs/{blob_id}; tool result is JSON with content_base64, content_type, size_bytes. Requires LITHTRIX_API_KEY.lithtrix_blob_list — GET /v1/blobs (optional page, per_page). Requires LITHTRIX_API_KEY.lithtrix_blob_meta — GET /v1/blobs/{blob_id}/meta. Requires LITHTRIX_API_KEY.lithtrix_blob_delete — DELETE /v1/blobs/{blob_id} (soft-delete). Requires LITHTRIX_API_KEY.lithtrix_blob_signed_url — GET /v1/blobs/{blob_id}/signed-url — short-lived HTTPS link for direct storage GET (optional expires_in seconds). Requires LITHTRIX_API_KEY. Treat URLs as read tokens.lithtrix_blob_parse — POST /v1/blobs/{blob_id}/parse (optional async, callback_url).lithtrix_blob_parse_status — GET /v1/blobs/{blob_id}/parse/{parse_id}.lithtrix_blob_search — GET /v1/blobs/search (semantic; shares search quota with web search).Static MCP tool schemas (no auth): GET https://lithtrix.ai/mcp/lithtrix-browse.json, GET https://lithtrix.ai/mcp/lithtrix-commons-read.json, GET https://lithtrix.ai/mcp/lithtrix-blob-upload.json (and -download, -list, -meta, -delete, -signed-url, lithtrix-blob-parse.json, lithtrix-blob-parse-status.json, lithtrix-blob-search.json).
The API key is read exclusively from process.env.LITHTRIX_API_KEY. It is never hardcoded. Pass it via:
Never paste your API key into the tool definition or source code.
| Variable | Required | Default | Description |
