 ## MCP client example
 Agentic Security includes an MCP stdio server in `agentic_security.mcp.main`.
 To list the available MCP tools from a local checkout:
 ```shell
 python examples/mcp_client_usage.py
 ```
 To call HTTP-backed tools, run the Agentic Security app first, then point the
 MCP server at it:
 ```shell
 agentic_security --host 127.0.0.1 --port 8718
 python examples/mcp_client_usage.py --agentic-security-url http://127.0.0.1:8718 --call get_spec_templates

 The `Module` class is designed to manage prompt processing and interaction with external AI models and tools. It supports fetching, processing, and posting prompts asynchronously for model vulnerabilities. Check out [module.md](https://github.com/msoedov/agentic_security/blob/main/docs/module.md) for details.
 ## MCP server
 The Agentic Security MCP server exposes the scanner's REST API as callable tools and reusable prompt templates, so any MCP-compatible client (Claude Desktop, Claude Code, custom agents) can drive security scans through natural language.
 ### Installation
 ```shell
 pip install -U mcp
 # From cloned directory
 mcp install agentic_security/mcp/main.py
 ```
 ### Using with Claude Desktop
 1. Start the Agentic Security FastAPI server (default port `8718`):
   ```shell
   poetry run agentic_security
   ```
 2. Install the MCP server into Claude Desktop:
   ```shell
   mcp install agentic_security/mcp/main.py --name "Agentic Security"
   ```
 3. Open Claude Desktop — the following **tools** are now available:
   | Tool | Description |
   |---|---|
   | `start_scan` | Launch a security scan against an LLM spec |
   | `stop_scan` | Halt an in-progress scan |
   | `verify_llm` | Check that an LLM spec is reachable |
   | `get_data_config` | Retrieve the current dataset configuration |
   | `get_spec_templates` | List available LLM spec templates |
 4. Or kick off a scan using one of the built-in **prompt templates**:
   - **`security_scan_prompt`** — runs a full scan with a configurable probe budget
   - **`verify_llm_prompt`** — confirms a spec is reachable before committing to a scan
   - **`adversarial_probe_prompt`** — enables multi-step attacks and asks Claude to summarise the worst findings
 ### Example conversation with Claude
 ```
 You: Use the security_scan_prompt for spec "openai/gpt-4o" with a budget of 500 probes.
 Claude: I'll kick off the scan now. Starting with verify_llm to confirm the spec is
        reachable, then launching start_scan with maxBudget=500...
 ```
 ### Using with Claude Code (CLI)
 ```shell
 # Add to your project's MCP config
 claude mcp add agentic-security -- python agentic_security/mcp/main.py
 # Then interact inline
 claude "Run a quick adversarial probe against my local LLM at http://localhost:8080/v1"
 ```

 Fuzzer module for performing LLM security scans.
 This module provides the core fuzzing logic for the Agentic Security scanner.
 It supports two scanning modes:
    - **Single-shot scan**: Sends individual prompts from selected datasets to
      probe LLM vulnerabilities (jailbreaks, prompt injection, etc.).
    - **Many-shot scan (MSJ)**: Injects probe prompts within multi-step
      conversations to test context-window attacks and many-shot jailbreaking.
 The module uses Bayesian optimization (via scikit-optimize) to adaptively
 focus scanning effort on high-failure-rate areas and supports early stopping
 based on configurable budget and failure-rate thresholds.
 Key components:
    - ``generate_prompts``: Async generator that yields prompts from lists or
      async sources.
    - ``get_modality_adapter``: Routes requests through image/audio adapters
      based on the LLM's modality.
    - ``process_prompt`` / ``process_prompt_batch``: Core prompt execution and
      response evaluation logic.
    - ``scan_module``: Scans a single prompt module with progress tracking.
    - ``perform_single_shot_scan`` / ``perform_many_shot_scan``: Top-level
      scan orchestrators.
    - ``scan_router``: Entry point that dispatches to the correct scan mode.

 """Config-driven registry for refusal classifiers and leak detectors.
 The registry maps a plugin *name* to a zero-argument *factory* that builds a
 detector. A detector is any object exposing ``is_refusal(response) -> bool``
 (the :class:`~agentic_security.probe_actor.refusal.RefusalClassifierPlugin`
 contract). This lets users enable, disable, or add custom detectors through the
 ``[detectors]`` section of ``agentic_security.toml`` instead of editing source.
 Built-in names registered here: ``pii`` and ``sandbox_escape``. The phrase-based
 ``default`` classifier and the ML ``ml_classifier`` are registered by
 :mod:`agentic_security.probe_actor.refusal` to avoid importing the trained model
 eagerly.
 Example configuration::
    [detectors]
    default = true          # phrase-based refusal classifier
    ml_classifier = true    # ML one-class SVM refusal classifier
    pii = true              # enable the PII / credential leak detector
    sandbox_escape = false  # keep the sandbox-escape detector off

 # MCP + Agno Integration
 This guide shows how to use Agentic Security's MCP server with [Agno](https://docs.agno.com/tools/mcp) agents.
 ## Setup
 Install Agentic Security with optional Agno support:
 ```bash
 pip install agno
 ```
 ## Starting the MCP Server
 Start the Agentic Security MCP server:
 ```bash
 python -m agentic_security.mcp.main
 ```
 For production, use the stdio transport (default with FastMCP):
 ```bash
 python agentic_security/mcp/main.py
 ```
 ## Examples
 ### Basic Verification with Agno
 ```python
 import asyncio
 from agno.agent import Agent
 from agno.tools.mcp import MCPTools
 from agentic_security.mcp.main import mcp
 async def verify_llm_spec():
    # Connect to Agentic Security's MCP server via stdio
    mcp_tools = MCPTools(
        command="python",
        args=["agentic_security/mcp/main.py"],
    )
    await mcp_tools.connect()
    try:
        agent = Agent(
            tools=[mcp_tools],
            instructions=[
                "You are a security testing assistant.",
                "Use verify_llm to test LLM specifications for vulnerabilities.",
                "Present results clearly with risk levels.",
            ],
            markdown=True,
        )
        await agent.aprint_response(
            "Verify this LLM spec: openai/gpt-4",
            stream=True,
        )
    finally:
        await mcp_tools.close()
 asyncio.run(verify_llm_spec())
 ```
 ### Running a Security Scan
 ```python
 import asyncio
 from agno.agent import Agent
 from agno.tools.mcp import MCPTools
 async def run_security_scan():
    mcp_tools = MCPTools(
        command="python",
        args=["agentic_security/mcp/main.py"],
    )
    await mcp_tools.connect()
    try:
        agent = Agent(
            tools=[mcp_tools],
            instructions=[
                "You are an LLM security scanning assistant.",
                "Use start_scan to initiate security scans on LLM endpoints.",
                "Use get_data_config to check available scan configurations.",
                "Report findings with severity levels.",
            ],
            markdown=True,
        )
        await agent.aprint_response(
            "Run a security scan on openai/gpt-4 with max budget 100",
            stream=True,
        )
    finally:
        await mcp_tools.close()
 asyncio.run(run_security_scan())
 ```
 ### Streamable HTTP Transport
 ```python
 import asyncio
 from agno.agent import Agent
 from agno.tools.mcp import MCPTools
 async def run_http_transport():
    mcp_tools = MCPTools(
        transport="streamable-http",
        url="http://0.0.0.0:8718/mcp",
    )
    await mcp_tools.connect()
    try:
        agent = Agent(
            tools=[mcp_tools],
            markdown=True,
        )
        await agent.aprint_response(
            "List available security scan templates",
            stream=True,
        )
    finally:
        await mcp_tools.close()
 asyncio.run(run_http_transport())
 ```
 ## Available Tools
 | Tool | Description |
 |---|---|
 | `verify_llm` | Verify an LLM model specification |
 | `start_scan` | Start an LLM security scan |
 | `stop_scan` | Stop an ongoing scan |
 | `get_data_config` | Retrieve data configuration |
 | `get_spec_templates` | Retrieve LLM specification templates |
 ## Notes
 - The stdio transport is recommended for local development
 - For production deployments, use the streamable-http transport
 - Always call `mcp_tools.close()` to clean up connections

 # MCP client usage
 Agentic Security exposes an MCP stdio server in `agentic_security.mcp.main`.
 The example client in `examples/mcp_client_usage.py` shows how to connect to
 that server, list available tools, and optionally call simple no-argument tools.
 ## List MCP tools
 From the repository root:
 ```shell
 python examples/mcp_client_usage.py
 ```
 This starts the MCP server as a subprocess with:
 ```shell
 python -m agentic_security.mcp.main
 ```
 The client initializes an MCP session and prints the available Agentic Security
 tools, including `verify_llm`, `start_scan`, `stop_scan`, `get_data_config`, and
 `get_spec_templates`.
 ## Call an HTTP-backed tool
 Some MCP tools call the Agentic Security HTTP app. Start the app in another
 terminal first:
 ```shell
 agentic_security --host 127.0.0.1 --port 8718
 ```
 Then point the MCP server at that app and call a no-argument tool:
 ```shell
 python examples/mcp_client_usage.py \
  --agentic-security-url http://127.0.0.1:8718 \
  --call get_spec_templates
 ```
 You can also set `AGENTIC_SECURITY_URL` directly:
 ```shell
 AGENTIC_SECURITY_URL=http://127.0.0.1:8718 python examples/mcp_client_usage.py --call get_data_config
 ```
 ## Use the package helper
 For tests or quick local checks, `agentic_security.mcp.client.run()` creates the
 same stdio session and returns the prompt, resource, and tool list results:
 ```python
 import asyncio
 from agentic_security.mcp.client import run
 async def main() -> None:
    _prompts, _resources, tools = await run()
    print([tool.name for tool in tools.tools])
 asyncio.run(main())
 ```

 # Collapse to CLI: remove MCP + Agno, make scanning agent-invocable
 ## Why
 The MCP server is a thin httpx proxy over the FastAPI server — every MCP tool
 just POSTs to `:8718`. So the "run MCP" path actually requires two processes
 (MCP stdio + web server) plus the auth/security surface of an exposed server.
 Coding agents (Claude, Codex) can call a local CLI directly with none of that.
 Goal: one stateless CLI command an agent can invoke and parse. Delete the rest.
 ## Scope
 MCP and Agno are internal/experimental — never a public contract. Hard-delete
 in one PR, bump version. No deprecation shims.
 ## Phase 1 — Delete Agno (dead code, zero risk)
 Imported by nothing, not a declared dependency, has undefined-variable bugs.
 - [ ] Remove `agentic_security/agents/` (only `operator_agno.py`)
 - [ ] Remove Agno references from `docs/mcp_agno_integration.md`
 ## Phase 2 — Delete MCP
 Core scanning (`probe_actor/`, `lib.py`) depends on none of this.
 - [ ] Remove `agentic_security/mcp/` (`main.py`, `client.py`, `__init__.py`)
 - [ ] Remove `examples/mcp_client_usage.py`
 - [ ] Remove `tests/unit/test_mcp.py`
 - [ ] Remove `docs/mcp_client_usage.md`, `docs/mcp_agno_integration.md`
 - [ ] Drop `mcp = "^1.22.0"` from `pyproject.toml`
 - [ ] Strip MCP sections from `Readme.md`
 ## Phase 3 — Make the CLI agent-invocable (the real work)
 Today scanning is config-file-driven: `init` writes `agesec.toml`, then `ci`
 reads it. An agent has to do two steps with hidden disk state. Replace with a
 direct one-shot command.
 Target UX (to be finalized in design):
 - [ ] `agentic_security scan --spec <file|->` — stateless, no `agesec.toml`
      required; spec from arg, file, or stdin
 - [ ] Streams machine-readable results to stdout (JSON lines), logs to stderr
 - [ ] Non-zero exit code on failures found (CI-friendly)
 - [ ] Decide fate of existing `ci` (config-driven) vs new `scan`: keep `ci`
      for config workflows, add `scan` for ad-hoc/agent use
 Open design questions:
 - Output format: JSON lines vs single JSON doc vs both behind a flag
 - Does `scan` need the FastAPI `app` at all, or call `fuzzer.scan_router()`
  directly via `lib.SecurityScanner` (preferred — fully standalone)
 - What's the minimal spec an agent must pass (llmSpec only? + datasets?)
 ## Phase 4 — Server stays, but secondary
 Keep `agentic_security server` (web UI) — it's the interactive surface. It is
 no longer the integration path for agents. Default bind is now `127.0.0.1`.
 ## Success criteria
 - An agent can run a full scan with a single CLI command, no server, no config
  file on disk, parse results from stdout.
 - `grep -ri "mcp\|agno" agentic_security/` returns nothing in source.
 - Existing fuzzer/probe tests still pass.

Devam Shah	d28c4b4b1e	feat: config-pluggable refusal classifiers and leak detectors PIIDetector and SandboxEscapeDetector were wired directly in probe_actor/refusal.py and the refusal classifier manager was populated from a hardcoded list, so the only way to toggle a bundled detector or add an organization-specific signature was to patch the module. Add a DetectorRegistry mapping plugin names to factories, assembled from an agentic_security.toml [detectors] section via build_from_config. Custom detectors load by import path ("pkg.module:ClassName"). refusal.py gains build_refusal_manager(config=None) reading the [detectors] table; all public symbols are preserved. Built-in leak detectors ship registered but disabled, so default refusal_heuristic behaviour is unchanged. Closes #82 Signed-off-by: Devam Shah <devamshah91@gmail.com>	2026-06-22 19:40:33 +05:30

zhanz5	f25520869f	merge: resolve conflict with upstream msoedov/agentic_security Merged upstream/main into fix/cost-calculation-model-aware. Conflict resolved in cost_module.py: - Kept upstream's updated PRICING table (2026-06-03 verified prices) - Kept upstream's DEFAULT_MODEL = "claude-sonnet" - Kept upstream's 50/50 input/output token split - Preserved our float \| None return type for unknown models - Preserved our logger.warning instead of raise ValueError	2026-06-05 14:15:08 +08:00
zhanz5	02b68b06ee	fix: make cost calculation model-aware instead of hardcoded to deepseek-chat Previously, calculate_cost() was always called without a model parameter, causing all scans to report costs based on deepseek-chat pricing regardless of the actual target model (e.g. gpt-4, claude-3-opus). Changes: - http_spec.py: Add 'model_name' property to LLMSpec that extracts the model field from the JSON request body. Returns 'unknown' if the body is not valid JSON or has no 'model' field. - probe_data/image_generator.py: Add 'model_name' pass-through property to RequestAdapter, delegating to the underlying LLMSpec. - probe_data/audio_generator.py: Same as above - add 'model_name' pass-through property to RequestAdapter. - probe_actor/cost_module.py: - Change return type from float to float \| None. - Unknown models now log a warning and return None instead of raising ValueError, so scans are not interrupted by unsupported model names. - Add logger import for the warning message. - probe_actor/fuzzer.py: Pass model_name to calculate_cost() in both scan_module() and perform_many_shot_scan() using getattr(request_factory, 'model_name', 'unknown'). - primitives/models.py: Update ScanResult.cost type from float to float \| None to accommodate unknown model pricing.	2026-06-05 13:59:59 +08:00

zhanz5	5e5469a1a7	fix: remove duplicate ProbeDataset class from msj_data.py msj_data.py contained a full copy of the ProbeDataset dataclass that was already defined canonically in probe_data/models.py, violating DRY and leaving a stale TODO comment in the source. Changes: - probe_data/msj_data.py: delete the 19-line duplicate ProbeDataset definition and the now-unused 'from dataclasses import dataclass' import; replace with a single re-export: from agentic_security.probe_data.models import ProbeDataset All call-sites inside the file (load_dataset_generic, prepare_prompts) continue to work unchanged because the field signatures are identical. The TODO comment is removed as the refactor is now complete. No changes required in consumers (fuzzer.py, test_msj_data.py) because they access ProbeDataset through msj_data's re-export.	2026-06-04 21:46:22 +08:00
