Tugra
Provenance-aware memory format for AI agents: every claim carries its source, age and boundary.
Install
Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).
tugraclaude mcp add tugra -e 'TUGRA_KASA=<TUGRA_KASA>' -e 'TUGRA_AKIS=<TUGRA_AKIS>' -e 'TUGRA_YETKI=<TUGRA_YETKI>' -- npx -y tugra@0.1.4
{
"mcpServers": {
"tugra": {
"command": "npx",
"args": [
"-y",
"tugra@0.1.4"
],
"env": {
"TUGRA_KASA": "<TUGRA_KASA>",
"TUGRA_AKIS": "<TUGRA_AKIS>",
"TUGRA_YETKI": "<TUGRA_YETKI>"
}
}
}
}
Environment variables
TUGRA_KASAVault directory holding the markdown facts.TUGRA_AKISDirectory where audit events are appended.TUGRA_YETKIAuthorization store. When set, every agent needs a profile; unset means single-user mode.

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.

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 tugrais 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.
License
Apache-2.0. See LICENSE and NOTICE.
The marketing page lives in ../site/ (npm run preview there). It is not deployed from this package.
Compatibility: TUGRA_KASA, TUGRA_AKIS, TUGRA_YETKI (and the older TALAMUS_* / MULTI_* names) still work as a fallback when the English name is unset.
Frequently asked questions
What is Tugra?
Provenance-aware memory format for AI agents: every claim carries its source, age and boundary.
How do I install Tugra?
It runs on your machine. In Claude Code: claude mcp add tugra -e 'TUGRA_KASA=<TUGRA_KASA>' -e 'TUGRA_AKIS=<TUGRA_AKIS>' -e 'TUGRA_YETKI=<TUGRA_YETKI>' -- npx -y tugra@0.1.4. For other clients, paste the JSON configuration from this page into their MCP settings.
Does Tugra need an API key?
Its registry entry lists no required key or secret. Some features may still need an account with the service it connects to.
Is Tugra open source?
Yes. Its code is on GitHub under the Apache-2.0 license.
Who maintains Tugra?
It is published by dogrucanemek-alt. AI.tn lists it but does not maintain or endorse it.
From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
