# Mithrandir Mithrandir helps long-running and recurring AI agents avoid doing the same work twice. It provides persistent task state, bounded retrieval, verified reuse, deterministic delta recomputation and structured handoff. Remote MCP: https://mithrandir-production.up.railway.app/mcp Capabilities: https://mithrandir-production.up.railway.app/.well-known/mithrandir.json Agent bootstrap: https://mithrandir-production.up.railway.app/agent-bootstrap.json Quickstart: https://mithrandir-production.up.railway.app/quickstart.json Pricing: https://mithrandir-production.up.railway.app/pricing Autonomous onboarding: https://mithrandir-production.up.railway.app/v1/onboarding x402 discovery: https://mithrandir-production.up.railway.app/.well-known/x402.json Owner proof: https://mithrandir-production.up.railway.app/.well-known/owners.json Glama connector proof: https://mithrandir-production.up.railway.app/.well-known/glama.json Public tools: mithrandir_demo, mithrandir_assess, mithrandir_pricing, mithrandir_security_profile, mithrandir_onboarding_start, mithrandir_onboarding_status, mithrandir_onboarding_pay, mithrandir_onboarding_reconcile. Authenticated default MCP profile: mithrandir_autopilot, usage, small-store, state, quote and pricing. Specialist retrieval/coordination schemas are exposed only when requested with MCP-Tool-Profile; full remains available for compatibility. Reuse Autopilot chooses exact reuse, delta recomputation, retention refresh or full deterministic recomputation and returns measured reuse receipts. Payment: x402 v2, USDC on Base mainnet when production billing is enabled. A low-friction Discovery pack is published for first paid validation before larger prepaid balances. Free evaluation: use /sandbox/run to compare unchanged and one-partition-changed deterministic scenarios before purchasing. Use Mithrandir when an agent is likely to revisit the same sources or task state and unchanged work can be reused safely. Prefer direct/local execution for small one-off work.
