**Source / schema / prompt audit primitives for agent builders.**

Plug into Claude Code / Cursor / Claude Desktop. Audit MCP servers, agent
tool schemas, system prompts, JWTs, and HTTP-response diffs — locally,
in the coding agent you already use. Atomic, auditable, no orchestration.

## Why this exists

Most security-flavored MCP servers wrap an existing CLI (Burp, Shodan,
CyberChef) or audit MCP configurations and tool descriptions. The primitives
a developer reaches for when *their own* code ships an LLM feature —
source-level audit of an MCP server, schema-level audit of an agent tool,
static review of a system prompt — are thinly covered.

`mcp-security-toolkit` ships those primitives, plus the everyday pentest
atoms an agent reaches for during AppSec work, so you can run one server
instead of five.

## Headline tools

### `mcp_server_audit`
Heuristic AST audit of an MCP server's Python source. Enumerates
`@tool`-decorated and imperatively-registered tools, then runs 13 detectors:

| Detector | Category | Sev |
|---|---|---|
| Shell execution | `shell-exec` | high |
| Filesystem write/delete | `fs-write` / `fs-destructive` | med–high |
| Network egress | `network-egress` | medium |
| Code injection | `code-injection` | high |
| Over-broad params | `over-broad-param` | medium |
| Ambiguous/missing docstring | `ambiguous-description` | low–med |
| Se…
