+### Connect your agents to Autter's MCP server
+
+`autter mcp connect` adds Autter's MCP server to every installed agent's user-level config (Claude Code, Codex, Cursor, VS Code, Gemini CLI, OpenCode). Only the URL is written; each agent signs you in with your Autter account the first time it uses it. `--dry-run` shows the changes, `--agent <name>` picks agents, and `autter mcp disconnect` removes the entry again.

+- `autter context "<task>"` returns, in one call, what Autter knows that matters for a task: the repository's memory facts, wiki pages and code structure, ranked and cut to a token budget. It prints Markdown for an agent to read: one line per item with its source, title and path, the fact id to cite (`rmf_…`), a `more:` line saying where to read further, and a `cursor:` line. It is the same as the `get_context` MCP tool, for agents that aren't connected to the Autter MCP server.
+  - It asks about the files changed in your checkout by default; name others with `--path` (repeatable) and functions or types with `--symbol`.
+  - `--budget <300-16000>` sets the tokens, `--include memory,wiki,code` picks the sources, and `--since <cursor>` leaves out what an earlier call already returned unchanged. `--json` prints the raw answer.
+- `autter memory skills install` writes the repository's own memory skill, generated by Autter from its memory facts, into the checkout: `.agents/skills/autter-repo-memory/SKILL.md` and a Cursor rule. Commit them and every teammate's agent has the memory, with or without the CLI. It replaces only files Autter wrote (`autter_generated: true` in their frontmatter) unless you pass `--force`. `autter memory skills preview` (or `install --print`) prints the files and writes nothing.
+- `autter mcp connect` adds Autter's MCP server (`https://api.autter.dev/mcp`, or your configured API address plus `/mcp`) as `autter` to each installed agent's user-level config, and `autter mcp disconnect` removes it:
+
+  | Agent | How |
+  |---|---|
+  | Claude Code | `claude mcp add --transport http --scope user`, or `mcpServers.autter` in `~/.claude.json` when `claude` isn't on PATH |
+  | Codex | `codex mcp add autter --url`, or `[mcp_servers.autter]` in `~/.codex/config.toml`; then `codex mcp login autter` |
+  | Cursor | `mcpServers.autter = {"url"}` in `~/.cursor/mcp.json` |
+  | VS Code | `servers.autter = {"type": "http", "url"}` in the user `mcp.json` (and each profile's existing one) |
+  | Gemini CLI | `mcpServers.autter = {"httpUrl"}` in `~/.gemini/settings.json` |
+  | OpenCode | `mcp.autter = {"type": "remote", "url", "enabled": true}` in `~/.config/opencode/opencode.json` |
+
+  Only the URL is written: the server signs you in with OAuth the first time an agent uses it. Agents that aren't installed are skipped, every file is backed up before it changes, comments and key order are kept, and running it again replaces the entry instead of adding a second one. `--dry-run` shows the plan and `--agent <name>` limits it.
+- The `repo-memory` skill now tells agents to call `autter context` first (or `get_context` when the MCP server is connected), to cite the fact ids that change what they do, and that `autter mcp connect` connects them.

+read it, and so should you. It has:
 
+- **Memory facts**: short, checked statements about the repository, each with an id
+  like `rmf_ab12cd34ef`. Cite the id when a fact changes what you do.
 - **The home page** (`MEMORY`): a short map every session needs.
 - **Area pages** (`areas/<slug>`): one per part of the codebase, each starting with
   `Path: <prefix>`, with the sections How it works, Conventions, What breaks, What
   works and Open threads. This is where the detail is.
 - **The ledger** (`ledger/what-works`): what the team tried and how it went (Works,
   Doesn't work, Team waves off), one line per item with its area in brackets.
 
-The `autter` CLI fetches it with the person's existing `autter login`. It covers the
-same ground as the Autter MCP tools `get_repo_memory` (with `paths` for area pages) and
-`search_context`. **If those MCP tools are available, use them. Otherwise use the

-   `home.body`. It is short. `areas` lists each area's `path`.
-2. **Before editing files**, run `autter memory for <the files> --json`. Read each

    question about behaviour, not a bare identifier. A `repo_memory_page` hit carries
    `metadata.slug` and `metadata.area`; open it with `autter memory show <slug> --json`.
+   Later in the session, `autter context "<new task>" --since <cursor>` returns only

    is the truth today. If they disagree, trust the code and tell the person.
