Lithtrix MCP vs Scrivener MCP

lithtrix_search

Search the web via Lithtrix and get credibility-scored results. Returns structured JSON with title, URL, snippet, source domain, and credibility_score (0–1) for each result. Higher credibility_score = more authoritative source (.gov=1.0, .edu=0.9, news=0.8, .org=0.7, other=0.5). Requires LITHTRIX_API_KEY environment variable.

lithtrix_register

Register a new agent with Lithtrix and receive a one-time API key. Call this tool once to obtain your LITHTRIX_API_KEY. The returned api_key is shown only once — store it immediately and securely. No authentication required. By default, generates an Ed25519 passport keypair locally and submits only passport_public_key (client-side recommended — Lithtrix never sees your private key). See https://docs.lithtrix.ai/passports and https://docs.lithtrix.ai/passport-derivation-spec. Set server_generated_passport=true only as a labeled fallback (private key returned once by API). Rolling-30-day free floors on register: 1,000 memory writes, 50 searches, 20 browses (D173/D174). New registrations do not receive a starting credit grant (D174). Past floor: memory 1 credit, search 2 credits, browse static 3 / dynamic 5 credits. Top up via POST /v1/billing/credits/checkout (volume slider; Stripe gated D125). Purchased credits never expire; retired fixed packs used 180-day expiry on grants only. Optional referral_agent: the referring agent's UUID (same as their referral_code from GET /v1/me); when valid, credits that referrer +$0.50 per signup (self-referral excluded; no cap). Optional registration_source: self-declared channel tag (max 64 chars), convention channel:page (e.g. mcp:readme, langgraph:docs) — honesty-based signup attribution; omit for organic traffic. agree_to_terms must be true (Gentle-Agent Agreement). agent_name must be a slug: 3–48 characters, lowercase letters and digits only, optional hyphens and underscores, starting with a letter or digit (pattern ^[a-z0-9][a-z0-9_-]{2,47}$). Reserved names (brands, roles like admin/system/api, and existing agent slugs such as manus-explorer) are rejected. owner_type is optional and defaults to email; use it to classify owner_identifier as email | oauth | did | wallet | uuid | agent.
