# MemCell

> Living memory for AI coding agents: recall before acting, report outcomes so confidence is earned.

- name: ai.memcell/memcell
- version: 0.8.0
- connection class: R2 (oauth_consent_once)
- trust: 92/100
- quality: 50/100 (needs work)
- owner: not claimed
- descriptor: https://api.protogrid.dev/v1/servers/ai.memcell%2Fmemcell
- tools: https://api.protogrid.dev/v1/servers/ai.memcell%2Fmemcell/tools

**An agent can connect after a one-time OAuth consent by a human.** Remote endpoint behind OAuth 2. Tokens stay with the agent; the registry only exposes the authorization metadata.

## Connection (mcpServers)

```json
{
  "mcpServers": {
    "memcell": {
      "type": "http",
      "url": "https://memcell.ai/mcp",
      "headers": {
        "Authorization": "Bearer ${MEMCELL_TOKEN}"
      }
    }
  }
}
```

Placeholders to fill: `${MEMCELL_TOKEN}`.

## Trust

- hygiene: 100
- liveness: 99
- freshness: 85
- provenance: 85
- drivers: +repository +dns-namespace +website +reachable +uptime-98% ~updated-43d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 50/100 (needs work)

### protocol: n/a (weight 25)

- n/a `protocol.modern`, `protocol.stateless`, `protocol.transport`, `protocol.list_ttl`: no remote answered a protocol handshake (not probed yet, unreachable, or local-only)

### authorization: 50 (weight 15)

- fail `auth.prm`: no Protected Resource Metadata (RFC 9728); clients cannot discover the authorization server
- pass `auth.as_metadata`: authorization server metadata reachable
- fail `auth.cimd`: no way for a new client to register (neither CIMD nor DCR)
- pass `auth.secret_in_url`: URL variables carry no secret

### tool hygiene: n/a (weight 30)

- n/a `tools.descriptions`, `tools.description_length`, `tools.schemas`, `tools.annotations`, `tools.directory_hints`, `tools.token_cost`, `tools.api_dump`: tool list unknown (behind auth, not probed, or empty)

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool list unknown

### dependencies: 50 (weight 15)

- warn `deps.known_vulns`: 1 advisory of lower severity or without a published fix: GHSA-5r4p-p66f-jhc7 in hono@4.13.9 (indirect, fixed in 4.13.11)
- fail `deps.mcp_sdk_version`: @modelcontextprotocol/sdk 1.30.1 has 3 known advisories (GHSA-22jm-h49p-29qw, GHSA-6prh-2h8m-c8cw, GHSA-6qxp-vccf-f47h); update @modelcontextprotocol/sdk to 1.32.0 or later
- pass `deps.resolvable`: memcell@0.8.0 resolved: 99 packages

- tools: unknown
- badge: [![protogrid quality](https://protogrid.dev/badge/ai.memcell/memcell.svg)](https://protogrid.dev/servers/ai.memcell/memcell)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.
