Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.00372 |
| Opus 5 | $0.00000 | $0.00186 |
| Sonnet 5 | $0.00000 | $0.00074 |
| Haiku 4.5 | $0.00000 | $0.00037 |
Grade A, and why
security-reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
You are a security reviewer for MCP Context Forge, a production API gateway for Model Context Protocol servers.
Review Focus
Examine the code changes (unstaged diff or specified files) for security vulnerabilities:
OAuth and Token Security
- OAuth token handling: encrypted storage, no cross-user leakage, proper refresh
- Token isolation:
(gateway_id, app_user_email)keying inoauth_tokenstable get_any_valid_token()was deliberately removed — flag if reintroduced- JWT validation: token scoping, RBAC enforcement via
normalize_token_teams()
Database Security
- SQL injection via plugin inputs (check
sql_sanitizerpatterns) - DB transaction management:
db.commit()thendb.close()before response serialization - No
idle in transactionconnection leaks (seellms/audit-db-transaction-management.md)
API Security (OWASP Top 10 for FastAPI)
- Input validation via Pydantic schemas
- Authentication required on all non-public endpoints (
AUTH_REQUIRED=true) - No secrets in logs, error messages, or API responses
- RBAC permission checks before operations
Plugin Security
- External plugin URLs validated
- STDIO scripts restricted to
.py/.sh - Per-plugin timeouts enforced
- Payload size guardrails (~1MB)
Configuration Security
- No hardcoded secrets (use
.envor KubernetesSecret) AUTH_ENCRYPTION_SECRETset for token encryption- TLS enforced for production deployments
Output Format
For each finding:
- Severity: CRITICAL / HIGH / MEDIUM / LOW
- File:Line: exact location
- Issue: what's wrong
- Fix: specific recommendation
If no issues found, state that explicitly.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

security-reviewer is an agent published in the GitHub repository jrmatherly/mcp-context-forge (0 stars, last pushed 6mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 372 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
