## What it does

Engram is a remote MCP server that saves each message of a conversation as sent, with no summarising or compression, and later retrieves the right part by meaning. Search runs on bge-base-en-v1.5 embeddings. The whole thing lives on Cloudflare: Workers running a Hono.js API, D1 for messages and metadata, Vectorize as the search index. Six tools are exposed over MCP: `create_conversation`, `append_messages`, `search`, `get_conversation`, `list_conversations`, `delete_conversation`.

There is no API key to copy. The server handles MCP authorization on its own (RFC 9728, 8414, 7591 plus PKCE): the client discovers it, registers, and opens a browser sign-in. A free account is created during that sign-in. The Claude plugin also brings a skill that tells the agent when to look in memory and what deserves saving.

Clients that only speak stdio need the `mcp-remote` bridge through `npx`, which drives the same browser flow. The older `npx @getengram/cli mcp` setup does not work — the CLI has no such command. Free covers 1,000 messages a month, Pro is $9/mo for 100,000, Team is $27 per seat per month for 500,000.

## When to use it
- recall last week's discussion of a schema by meaning, not by date
- restore project context in a fresh agent session
- keep a full transcript instead of a summary
- separate memory per organization and give the team seats
- delete a conversation along with its data

## Example prompts
- Search memory for what we decided about auth last time
- Save this conversation and tag it `api-design`
- List my conversations from the past week
