## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Supply Chain Security**: 0/100
  - No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.
  - Known CVEs could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.
  - Install-script risk not yet assessed.
  - Dependency health could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.
- **Provenance & Transparency**: 48/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 18 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 51/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 362 tokens (~40/item across 9 items; 9 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 63/100
  - Stability observed for 19 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## Install

### How do I install the MCP Memory server?

MCP Memory runs locally as a container image, launched with docker run --rm -i -e DB_PATH ghcr.io/germaniu/mcp-memory:0.6.0. Ready-made configuration for Claude, Cursor, VS Code, Codex and 3 more is on this page, copied from each client's own documentation.

### Claude

```bash
claude mcp add germaniu-mcp-memory -- docker run --rm -i -e DB_PATH ghcr.io/germaniu/mcp-memory:0.6.0
```

This image reads DB_PATH. Set it in your client's env block for this server; docker run -e passes it through to the container.

## Common questions

### What is the MCP Memory server?

MCP Memory is listed in the public MCP registry as io.github.GermaniU/mcp-memory. Local persistent memory for AI agents: SQLite + FTS5 (BM25) lexical search, zero external infra. This page covers its container image (ghcr.io/germaniu/mcp-memory).

### Is the MCP Memory server safe to use?

MCP Memory scores 43 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the MCP Memory server expose?

MCP Memory exposes 9 tools: memory_save, memory_search, memory_delete, memory_list, memory_update, and 4 more. Their descriptions and schemas cost roughly 282 tokens of context every time the server is loaded.

### Is the MCP Memory server still maintained?

MCP Memory is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the MCP Memory server under?

MCP Memory declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
