Stashpad

Stashpad

Local memory for any AI coding agent: an MCP server and CLI that keep plain Markdown notes with sources, a review queue and search.

[CI] [npm] [MIT license]

[Stashpad in a terminal: a person saves and pins a decision, an agent's note waits for review, recall finds both for a request, and the brief brings the pinned rule back after compaction]

Works with Claude Code, Codex, Cursor, VS Code, Gemini CLI and any other MCP client, or with no MCP at all (plain commands and an AGENTS.md block). No model, no cloud, no dependencies: Node 20 or newer.

Quickstart

npm install -g stashpadstashpad setup                  # prints the MCP settings for your agent app (generic, claude-code, vscode, codex)stashpad doctor --client        # starts the server the way your agent app does and checks it answers

Expected: client start: the server answered with 8 tools in ... ms and Nothing is broken.

Claude Code users can install the plugin instead, which also adds the hooks below: /plugin marketplace add laaielichter/stashpad, then /plugin install stashpad@stashpad (or stashpad@reverseport from the ReversePort marketplace).

Why Stashpad?

• Your agent stops forgetting after compaction. Pinned rules and the latest handoff come back at the start of every session and right after /compact.
• Rules you set stay in front of the agent. stashpad pin keeps the few rules that matter in every brief; each prompt gets only the memories that clearly match it.
• Nothing ends up in memory behind your back. Agent, tool and web notes wait for a person; near-copies, secrets and hidden text are refused.
• You can read, fix and keep it. Memories are Markdown files with a source and dates, in your project, in git if you want. Old facts are ended, never overwritten.
• It keeps working. One store per project (worktrees share it), a lock for parallel writers, snapshots before changes, doctor that says what to fix.

How it compares

What Stashpad does not do: semantic search (word search finds about 2 of 3 reworded questions in our eval), automatic extraction of memories from chats (by design), sync between computers (use git), or a shared server for a team.

Start and end of a session

stashpad brief                  # short summary: pinned rules, newest memories, open handoffstashpad recall "add a postgres migration"    # the few memories that clearly match a requeststashpad handoff leave --text "Half done: auth. Next: tests."   # a note the next session reads oncestashpad sync-agents AGENTS.md  # put the brief in a file agents already read (no MCP needed)

With the Claude Code plugin these run as hooks: at session start and after compaction, on each prompt, and before compaction (an automatic handoff). See docs/HOOKS.md. Agents: read AGENT-GUIDE.md.

Develop

Requires Node 20 or newer. No other dependencies.

npm test                 # run the testsnpm run build            # build dist/node bin/stashpad.mjs --help

Memories live in .stashpad/memories of the project: the nearest folder above that has one, else the git root, so subfolders and git worktrees share one store. stashpad where shows which store a folder uses and why. Set STASHPAD_DIR or pass --dir to choose yourself. What is true in every project (your language, your commit style) goes in the global store: add --global (or -g).

Use it

stashpad save db-choice --kind decision --source-type user --source-ref "statement in chat" --text "We keep data in SQLite."stashpad search "sqlite" --jsonstashpad save db-choice-v2 --kind decision --source-type user --source-ref "later statement" --text "We keep data in Postgres." --supersedes db-choicestashpad history db-choice-v2stashpad search database --kind decision --as-of 2026-03-01 --explain   # what was decided on that day, and why it matchedstashpad entities                  # names, tools and files the memories talk aboutstashpad about Postgres            # every memory about it, and what is mentioned with itstashpad confirm db-choice-v2      # still true; doctor flags agent memories nobody confirmed for 180 daysstashpad handoff leave --text "Half done: auth. Next: tests."   # a note the next session reads oncestashpad handoff claim             # take it (a person's notes first); listing never takes onestashpad feedback db-choice --signal stale   # helpful, stale or wrong; wrong also asks for it to endstashpad lint                      # what deserves a look; changes nothing

The command line, the MCP server and the review page can run at the same time: every write takes a short lock on the store.

Writes from agents, tools and the web wait in review:

stashpad reviewstashpad accept <id>stashpad reject <id> --reason "not verified"stashpad audit

Use it from an MCP client

stashpad setup prints the right block for your client, with the full path to Node (a bare node is the most common reason a server does not connect). It looks like this:

{  "mcpServers": {    "stashpad": {      "command": "/full/path/to/node",      "args": ["/full/path/to/stashpad/bin/stashpad.mjs", "mcp"]    }  }}

Eight tools: stashpad_search, stashpad_get, stashpad_recent, stashpad_about, stashpad_save, stashpad_forget, stashpad_handoff, stashpad_feedback.

Check it, import into it

stashpad eval                          # 40 notes, 33 queries (English and Dutch), safety checks; no language model is called. Paraphrased questions are measured too (about 2 of 3 found): word search misses some rewordings, and that is reported openly.stashpad import notes.jsonl            # queue memories from an export; they wait for reviewstashpad export --out memories.jsonl   # back up current memories as JSON Lines (--all adds ended ones)stashpad save <id> --kind fact --source-type user --source-file notes.txt --text "..."   # keeps a copy of the raw source

stashpad review also shows when a waiting memory may conflict with a current one, and whether accepting it would end that one.

Review in a page

stashpad ui            # opens http://127.0.0.1:4317/ to review, search and read the audit logstashpad ui --open     # the same, and opens the page in your browser

Only this computer can reach the page. It is a small local page with no outside resources. See the decision.

Imports come in as JSON Lines (id, kind, text, optional valid_from, source_ref) or as plain text, one fact per paragraph.

Principles

• Plain files first. The files are the source of truth.
• Nothing from an agent, tool or web page is stored until a person accepts it.
• Secrets are refused at write time (keys, tokens, JWTs, Bearer tokens, passwords in connection strings).
• Invisible characters are refused, and look-alike or split-up words cannot hide an instruction or a secret.
• Instruction-like text (English and Dutch) is flagged for the reviewer.
• A gatekeeper refuses agent notes that are too short or near-copies of an existing or waiting memory, and logs the refusal in the audit log. Notes a person writes are never blocked.
• Limits: 4000 characters per memory, 200 writes waiting for review.
• Recalled text is labelled as data, not instructions.

Docs

• Search words and synonyms
• Handoffs, feedback, lint, expiry and ReversePort
• Hooks: survive compaction, pinned rules, recall per prompt
• Optional encryption
• Architecture
• Changelog

• Updating safely: snapshots, restore, migrate
• Memory file format
• Search backend decision
• No vector search for now
• Third-party notices. Code is ported with npm run port, which refuses any license except MIT, Apache-2.0, BSD-2-Clause, BSD-3-Clause and ISC.

FAQ

Does Stashpad send anything anywhere? No. It makes no network calls, calls no model and has no telemetry. The review page listens only on this computer.

Where are my memories? In .stashpad/memories of your project (stashpad where tells you). They are Markdown files you can open, edit and commit.

Can an agent write whatever it wants into memory? No. Agent writes wait for a person (stashpad review or stashpad ui). Secrets, invisible characters and near-copies are refused, and everything recalled is labelled as data, not instructions.

My MCP client says the server failed. Run stashpad doctor --client. It starts the server the way an agent app does and tells you what to fix.

Sister tools

From the same author; local, open source, each with its own MCP server.

• ReversePort: reverse engineer apps, games, binaries and websites and port them between Godot, Unity, Unreal, three.js and languages. re_case remember proposes a proof case's findings to Stashpad's review queue (how).
• agentdisk: the disk report for coding agents. Finds the worktrees, checkpoints and dependency folders agents leave behind and cleans up only what is safe, with undo.

In Claude Code you can get all three from one marketplace: /plugin marketplace add laaielichter/reverseport, then /plugin install reverseport@reverseport, stashpad@reverseport or agentdisk@reverseport.
