Engram is a persistent, long-term memory layer for AI agents and assistants. Claude, ChatGPT, Grok, Cursor and any MCP client share one memory, stored as plain markdown notes: your knowledge base, second brain and AI context in one place. No extraction step: the memory is the note itself, so you can read exactly what your AI remembers and fix it. Edit your memory in Obsidian (real-time sync), the web app, or on your phone. Hybrid keyword + semantic search (RAG over your notes) finds exact strings like error messages, config keys and IDs. Remote MCP server over Streamable HTTP with OAuth 2.1; notes encrypted at rest.

Build, validate and deploy workflows as Cloudflare Workers in your own account, with approval.
Give AI assistants tested calculations with inspectable results. BusCalc 1.6.0 exposes 26 free tool families: 23 mathematical families and three attributed public-data lookups. Use Decision Feasibility, financial mathematics, probability, statistics/regression, algebra/matrices, units, pricing, loans, fleet and recipe costs, precious-metal transaction models, fuel/currency costs, utility energy calculations and weather-impact analysis. Fetch timestamped gold, silver, platinum and palladium USD spot snapshots, dated EIA fuel/energy and ECB currency references, and NOAA/NWS observations, forecasts, official alerts and coastal station readings. Published energy averages are not live tariffs; forecasts are not observations; dealer offers are user-entered. Supports MCP 2026-07-28, 2025-11-25, 2025-06-18 and 2025-03-26 through the same Streamable HTTP endpoint. Includes 29 read-only resources, five guided prompts and curated argument completions. Connection, discovery, calculations and error recovery were tested with maintained official MCP clients. Successful math returns named results, units, formulas, assumptions, source links and an unsigned replayable calculation receipt. Lookups return attributed snapshots. No trade execution, emergency service, safety clearance or guaranteed planning window. Direct access requires no account/key; shared pilot limits apply. Optional integration keys support pseudonymous attribution without higher quotas. No private-project access. Guide and OpenAPI: https://buscalc.com/for-ai/
