npx tugra init

That creates a vault, writes a sample fact, and prints a config block. Paste the block into your MCP client. On a TTY, npx tugra prints help and exits. Piped (Claude Desktop, Cursor, Claude Code) it is the MCP server.

Provenance-aware memory for AI agents. Every claim carries its source, its age, and its boundary. There is no cloud.

What it is

A fact that cannot name where it came from is not a fact. Tugra stores each claim as a file whose frontmatter holds source, last verification date, shelf life, and — when the topic is off-limits — a boundary that forbids invention. Search ranks by token score, then freshness, then confidence. Retired and rotten facts stay out of the default set.

Tools

Tool	What it does
fact_search	Search the vault. Retired/rotten omitted unless archive: true.
fact_read	Read one fact by uid. Body is escaped before the model sees it.
fact_propose	Write a draft. Secret patterns are rejected before any write. type: "boundary" is always quarantined.
event_report	Append a local telemetry line. No network.

Stored field names stay in the vault's native shape (kaynak, guven, raf_omru, sinir). The tool names and parameter names above are the public contract.

Install — env paths (optional)

tugra init is enough to start. Override the two paths only if you already have a vault elsewhere. Without them, the server looks next to the installed package — that is wrong for a bare npx with no init.

• TUGRA_VAULT — vault (markdown facts)
• TUGRA_EVENTS — telemetry directory

Authorization: if no authorization store is configured, single-user mode is on — search and propose work without a profile. If an authorization store is configured (a yetki/ directory, or TUGRA_AUTH), each agent needs a JSON profile or search returns unauthorized.

Codex

~/.codex/config.toml:

[mcp_servers.tugra]
command = "npx"
args = ["-y", "tugra"]

[mcp_servers.tugra.env]
TUGRA_VAULT = "/absolute/path/to/vault"
TUGRA_EVENTS = "/absolute/path/to/events"

Windows: use a full path (C:\\Users\\…\\vault). Node 20 or newer.

More client notes: docs/install.md.

Shared-vault authorization (optional)

Single-user setups do not need this. Add TUGRA_AUTH only when several agents share one vault and each needs its own profile (mcp-readonly@tugra and others as JSON files in that directory). A missing profile then returns unauthorized. An empty TUGRA_AUTH is treated as unset — single-user mode stays on.

Host library surface (not the MCP wire)

The MCP tools (fact_search, fact_read, fact_propose, event_report) enforce authorization on every call. The published package also ships dist-paket/akis.js and dist-paket/yetki.js so a host application (cron, mirror, cockpit) can write telemetry without going through JSON-RPC.

Those modules are public on purpose. akisBildir({ atlaYetki: true }), eylem: "yetki_talebi", and dosyaYoksaIzin (default true) skip or relax the check. harcamaEkle mutates a profile. The host that imports them owns authorization. The MCP wire cannot set these flags — the tool schema does not accept them.

Scale vault vs target vault

A0–A5 levels are facts (yonetisim.yetki.a0 … a5) in a vault. The stdio server reads them from TUGRA_VAULT, or from the cockpit kasa/ when that variable is unset.

tugraArac / createTugraMcp take an optional kasaKok (the write/search target). Scale does not follow that target. It defaults to varsayilanKasa() — the same central vault the stdio server uses. A host that points kasaKok at a data-only tree keeps using the cockpit / TUGRA_VAULT scale. To read scale from a different tree, pass skalaKasa explicitly.

All four tools share one resolver. This is the contract: separate target + central governance stays reachable. YAYIN/12 briefly defaulted scale to kasaKok; that broke the split-root host. YAYIN/13 restores the central default.

What we do not guarantee

• No cloud sync. The vault is the files you pointed at. Nothing is uploaded.
• No automatic merge. Two writers, two files. You reconcile.
• No delete in this release. Retirement exists; erasure is later.
• No automatic conflict detection. Contradictory facts can sit side by side until a human says otherwise.
• No hosted service. npx tugra is a local stdio process.

This package is not published as a SaaS. There is no price table here.

Requirements

• Node.js 20 or newer. This is a support decision, not a technical floor: the package is tested on 20 and 22 in CI, and it also runs on 18 — but 18 is past its end of life, so we do not support it.
• A vault directory you own

Topic map (optional)

<vault>/_konu-haritasi.json — { "desen", "bayrak", "konu" } rules in harita, alt_kirilim, and stem. If the file is missing the map is empty: unknown text falls back to kurum.genel or dunya.<world>.genel. Broken or over-long patterns are skipped and logged. This package does not ship a company taxonomy.

Compatibility: TUGRA_KASA, TUGRA_AKIS, TUGRA_YETKI (and the older TALAMUS_* / MULTI_* names) still work as a fallback when the English name is unset.
