Local-first governed memory for AI agents, with persistent identity,
tamper-evident history, verification, and constraint-aware decisions.
Tell your AI: “Check the ArkHive.”
ArkHive is an open-source
Model Context Protocol server for developers
and teams that want Claude, Codex, and other MCP clients to retain accountable
context across sessions without sending memory to a hosted service by default.
## What you get
Memory that survives the session. Your AI writes what it did and reads it
back next time — no blank slate every morning.
Tamper-evident history. Every record is hash-chained (SHA-256). Edit,
delete, or reorder any past record and verification fails — you get evidence
of change, not silent rewriting.
Local-first, no telemetry. The chain is a plain SQLite file on your
machine. Nothing is transmitted unless you explicitly opt in.
### Verify it yourself — one command, no key
Don't take "tamper-evident" on faith. Run the proof:
bash
git clone https://github.com/sammyboi81/arkhive && cd arkhive
./scripts/verify.sh # or: python -m benchmark
It writes a throwaway hash-chained ledger, verifies it clean, then forges one
block with a direct SQL edit and shows verification catch it. Real output:
[3] verify (untouched): blocks=20 brokenlinks=0 -> INTACT — context provably unbroken
[4] TAMPERED block idx=10: 'event10' -> 'FORGEDEVENT' (direct SQL edit, no hash recomputed)
[5] verify (after tamper): blocks=20 brokenlinks=1 -> TAMPERED — 1 broken links
RESULT: PASS - tamper-evidence proven.
A clean chain verifies with 0 broken links; a single forged edit is
caught. Your real data/chain.db is never touched. For the honest limits of
what a hash chain can and cannot protect, see

> New: the Claude Code Seatbelt. Hooks that make Claude Code (and Cursor) ask before anything irreversible, remember the
> project between sessions on this chain, and refuse to say "done" until the code ran. Engine: pip install sentarion-mcp

## Install in one command
bash
python -m pip install arkhive-mcp
The MCP command is arkhive-mcp.
> Renamed: this package was formerly published as humane-intelligence
> (still installable, now frozen). ArkHive is the product;
> #HumaneIntelligence is the movement.
## Connect an MCP client
### Claude Desktop
Add this entry to your Claude Desktop MCP configuration, then restart Claude
Desktop:
json
"mcpServers": {
"arkhive": {
"command": "arkhive-mcp",
"args": []
If Claude Desktop cannot find commands installed by pip, replace
arkhive-mcp with the absolute path printed by:
bash
python -c "import shutil; print(shutil.which('arkhive-mcp'))"
### Codex
bash
codex mcp add arkhive -- arkhive-mcp
Confirm it is configured with:
bash
codex mcp list
## Available tools
| Tool | What it does |
| birth | Creates a stable agent identity with an explicit covenant. |
| remember | Appends a hash-linked, tamper-evident record for a born identity. |
| recall | Retrieves prior records so an agent can ground the current session. |
| verify | Recomputes and checks the local chain for later alteration or broken links. |
