# io.github.localstack/localstack-mcp-server

> A LocalStack MCP Server providing essential tools for local cloud development & testing

- name: io.github.localstack/localstack-mcp-server
- version: 0.5.0
- connection class: L0 (run_local_package)
- trust: 81/100
- quality: –/100 (not scored)
- owner: not claimed
- descriptor: https://api.protogrid.dev/v1/servers/io.github.localstack%2Flocalstack-mcp-server
- tools: https://api.protogrid.dev/v1/servers/io.github.localstack%2Flocalstack-mcp-server/tools

**Runs on your machine: something must execute the package.** Only local packages are published (npm, PyPI, OCI, …). The registry never executes them, so tools are unknown until you run it.

## Connection (mcpServers)

```json

  "mcpServers": {
    "localstack-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "@localstack/localstack-mcp-server@0.5.0"
      ],
      "env": {
        "LOCALSTACK_AUTH_TOKEN": "${LOCALSTACK_AUTH_TOKEN}",
        "AWS_ACCESS_KEY_ID": "${AWS_ACCESS_KEY_ID}",

Placeholders to fill: `${LOCALSTACK_AUTH_TOKEN}`, `${AWS_ACCESS_KEY_ID}`, `${AWS_SECRET_ACCESS_KEY}`, `${AWS_SESSION_TOKEN}`, `${AWS_REPLICATOR_SOURCE_AWS_ACCESS_KEY_ID}`, `${AWS_REPLICATOR_SOURCE_AWS_SECRET_ACCESS_KEY}`, `${AWS_REPLICATOR_SOURCE_AWS_SESSION_TOKEN}`.

## Trust

- hygiene: 100
- liveness: n/a
- freshness: 65
- provenance: 80
- drivers: +repository +namespace-matches-repo ~liveness-unmeasured ~updated-124d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality –/100 (not scored)

Not scored: fewer than three checks apply, usually because no remote answered a credential-free probe or the server is a local package.

### 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: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### 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`: 2 advisories of lower severity or without a published fix: GHSA-vfj7-8cjw-p6xm in braces@3.0.3 (indirect, no fix yet), GHSA-w5hq-g745-h8pq in uuid@10.0.0 (indirect, fixed in 11.1.1)
- fail `deps.mcp_sdk_version`: @modelcontextprotocol/sdk 1.30.1 has 1 known advisory (GHSA-6qxp-vccf-f47h); update @modelcontextprotocol/sdk to 1.31.0 or later
- pass `deps.resolvable`: @localstack/localstack-mcp-server@0.5.0 resolved: 252 packages

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