HIGHLong base64-encoded blob hidden in the skill documentationSS-SKILL-INJECT-B64-PAYLOAD-01 · Prompt injection · mcp-server/src/burpsuite_mcp/knowledge/deserialization.json
A base64 string of 128+ characters appears in a documentation file. Encoded prompt injection hides the hostile instruction in base64 — invisible to keyword filters — and relies on the agent's ability to decode it at runtime. There is no normal authoring reason to embed a multi-hundred-byte base64 blob in skill docs.
- Decode the base64 string and confirm it is not an instruction directed at the agent.
- Move any legitimate binary or signature data into a dedicated file (
*.sig,SIGNATURES) outside the documentation.

Praetor
Agentic DAST orchestrator for Burp Suite.
Renamed in v1.0 fromburpsuite-swiss-knife-mcpto Praetor. The GitHub repo is nowgithub.com/TyrusRC/praetor(old URLs redirect). Python package directory unchanged this release; binary names (praetor-mcp,praetor-burp-ext-1.0.0.jar) are new. Backwards-compatible script aliases retained for one release cycle.
Praetor is a Model Context Protocol (MCP) server that turns Claude Code (or any MCP-aware LLM client) into a Burp-native agentic pentester. It exposes Burp's HTTP capabilities, scanner, sitemap, proxy history, and Collaborator, plus a knowledge-driven probe engine (128+ matchers), SAST + secrets layer (opengrep / gitleaks / trufflehog / git-dumper / Noir), an 11-agent team, and a save-finding pipeline with persistent target memory. Every request routes through Burp, so every finding is replayable from the Burp UI and citable by Logger index.
Authorized Use
This is an offensive security tool. Use only on systems where you have explicit written permission to test (bug bounty scope, signed penetration test, red team contract, internal lab). The authors are not responsible for misuse.
Architecture
LLM client <- stdio MCP -> Python MCP server <- HTTP -> Java Burp extension <- Montoya API -> Burp Suite- The Java extension exposes a REST API on
127.0.0.1:8111and tunnels HTTP traffic through Burp's proxy listener (127.0.0.1:8080) so all probes appear in Proxy history. - The Python MCP server is a thin client that the LLM speaks to via stdio.
- Target intelligence is persisted to
.burp-intel/<domain>/(gitignored).
Features
- MCP tool surface covering recon, scan, exploit, browser, auth, research, and reporting.
- HTTP send tools that route through Burp's proxy (curl-style, raw, repeater, intruder, concurrent).
- Adaptive scan engine driven by a JSON knowledge base (matchers + craft guidance) mapped to OWASP Top 10 (Web / API / LLM / Mobile), OWASP WSTG, PayloadsAllTheThings, HackTricks Web + Cloud — see the Coverage table.
- Native vuln-class orchestrators where no third-party covers the surface:
test_csrf,test_ssrf,test_ssti(SSTImap-modeled, multi-phase: polyglot → math distinguisher → engine-specific capability probes → optional blind sleep),test_xxe,test_websocket(CSWSH upgrade-handshake),test_prototype_pollution. - Native auth attack tooling with zero external deps:
forge_jwt(8 attack modes),crack_jwt_secret(HS dictionary),test_login_bypass,test_mfa_bypass,test_session_lifecycle,analyze_reset_tokens(entropy + sequential detection). - Third-party wrappers proxied through Burp: sqlmap, dalfox, commix, nuclei, ffuf, katana, subfinder, amass, wafw00f, arjun, gau, waybackurls, wpscan, nikto.
- SAST + secrets layer (v1.0):
audit_crawled_artifactsopengrep-over-proxy-bodies (DOM clobbering / proto pollution / postMessage),run_opengrep_sourcesource-tree SAST,run_gitleaks+run_trufflehog(live verification = HIGH severity floor),dump_exposed_gitchains withdiscover_common_files.git/HEADto reconstruct repo + extract secrets. Noir OpenAPI ingest viaimport_scope --format noir_json. - Active LLM/MCP probes (v1.0):
ai_prompt_injection,rag_injection,mcp_server_attacks,mcp_tool_poisoning,vector_db_injection,echoleak(CVE-2025-32711). Declarative prompt-injection guardrail (inspect_for_prompt_injection). - CI integration (v1.0): SARIF 2.1.0 + JUnit XML exporters, compliance-framework tags (OWASP / PCI-DSS / HIPAA / SOC2 / GDPR / CWE),
intensity=safe|normal|aggressiveflag, per-engagement cost cap (set_engagement_cost_cap), auto-PoCgenerate_repro_scriptrendering runnable curl from the finding's logger_index. - Save-finding pipeline with a 7-question gate (
assess_finding) and per-program policy overrides. - Stealth headless browser (CloakBrowser — patched Chromium binary with source-level fingerprint fixes, not JS shims) that proxies through Burp.
- Fast history queries:
get_proxy_count(sub-ms),since_indextail polling,hostexact-match filter, ByteArray in-place body search. - Persistent target memory with staleness detection and cross-target pattern reuse.
- Operator override surfaces for severity, scope filter, NEVER-SUBMIT class, confidence floor.
Requirements
- Burp Suite Professional or Community Edition
- Java 21+
- Python 3.11+ with uv
- An MCP-aware LLM client (Claude Code, Claude Desktop, etc.)
Optional:
- Go (for
subfinder,nuclei,katana) - Burp Professional for scanner control and Collaborator
Burp Edition Compatibility
Professional — full support. Default target environment.
Community — supported with manual setup. Almost everything works because the extension and MCP server use Burp's Montoya API for HTTP/proxy/scope, not the Pro-only scanner pipeline. Pro-only features degrade gracefully:
| Pro-only feature | Tools that depend on it | Community workaround |
|---|---|---|
| Active scanner | scan_url, crawl_target, get_scan_status, cancel_scan, get_scanner_findings, get_new_findings, get_issues_dashboard | Use auto_probe (knowledge-driven sweep), fuzz_parameter, fuzz_with_feedback, and the native test_* orchestrators (test_csrf / test_ssrf / test_xxe / test_websocket / test_prototype_pollution / test_login_bypass / test_mfa_bypass). These run through the extension's HTTP API and do not require Burp's scanner. |
| Burp Collaborator | generate_collaborator_payload, auto_collaborator_test, get_collaborator_interactions, collaborator_pool_status | Operator supplies an OOB callback URL — interact.sh / webhook.site / requestcatcher.com / a self-hosted DNS box — and passes it explicitly into payloads. Rule 9a forbids fabricating domains. |
| Intruder at full speed | send_to_intruder_configured | Community throttles Intruder heavily. Use concurrent_requests (Python-side parallelism through Burp proxy) for legitimate parallel testing without the throttle. |
Run check_pro_features() at session start to confirm which Pro capabilities the operator's instance exposes — the MCP server detects them at runtime, so Community users get a clear "not available" message instead of a silent hang.
Installation
Pick the level of automation you want.
Quick — uvx (no clone needed for the MCP server)
The MCP server runs straight from the source tree with uvx. You still need the Burp extension JAR loaded in Burp Suite — see the Manual section below for that part.
uvx --from "git+https://github.com/TyrusRC/praetor.git#subdirectory=mcp-server" \
burpsuite-swiss-knife-mcpOr in .mcp.json:
{
"mcpServers": {

}
}
}On Windows replace the command with C:\\...\\.venv\\Scripts\\python.exe. On WSL with Burp on the Windows host, add an env block setting BURP_API_HOST to the Windows host IP and bind the extension to 0.0.0.0 in the Swiss Knife config tab.
Environment Variables
| Variable | Default | Purpose |
|---|---|---|
BURP_API_HOST | 127.0.0.1 | Burp extension API host |
BURP_API_PORT | 8111 | Burp extension API port |
BURP_API_TIMEOUT | 30 | HTTP timeout in seconds |
BURP_PROXY_HOST | 127.0.0.1 | Burp proxy listener host |
BURP_PROXY_PORT | 8080 | Burp proxy listener port |
The Java extension also accepts JVM system properties swissknife.proxy.host and swissknife.proxy.port (highest precedence).
Usage
Once .mcp.json is loaded by your MCP client, the tools are available to the agent. A typical session:
configure_scopeto set include/exclude patterns and auto-filter tracker domains.browser_crawlordiscover_attack_surfaceto map the target.auto_probeto run knowledge-driven probes on parameters.assess_findingfollowed bysave_findingfor each suspected issue.generate_reportto export findings.
The agent receives expert methodology through the skill files in .claude/skills/. Operators steer the agent by passing override flags or by editing .burp-intel/programs/<slug>.json per-engagement policy.

MCP Prompts
The server publishes ready-to-run workflow templates. Surface them in your client (/mcp listing or the prompt picker) and pass arguments to launch a phase.
| Prompt | Args | Purpose |
|---|---|---|
hunt-target | target | Standard hunt loop: scope → recon → probe → verify → save. |
verify-finding | vuln_type, endpoint, evidence | Walk a suspected finding through the 7-Question Gate before saving. |
triage-program | program | Set per-program policy, scope, and override defaults at engagement start. |
chain-findings | domain | Walk saved findings and propose chains that lift NEVER-SUBMIT items into impact. |
save-finding-checklist | vuln_type, endpoint | Pre-save checklist enforcing replay → assess → save. |
MCP Resources
Read-only context the agent can attach without spending tool budget. URIs:
| URI | Returns |
|---|---|
burp://rules/hunting | The 28 always-active hunting rules (HARD/DEFAULT/ADVISORY). |
burp://rules/engineering | The 4 engineering rules. |
burp://skills/{name} | One skill markdown file by stem (hunt, verify-finding, chain-findings, …). |
burp://knowledge/index | List of all knowledge categories with context counts. |
burp://knowledge/{category} | Raw JSON for one category (probes + matchers + craft guidance). |
burp://intel/{domain}/{kind} | Saved target intel: profile, endpoints, coverage, findings, fingerprint, patterns, notes. |
burp://findings/{domain} | Findings JSON for one domain (alias of burp://intel/{domain}/findings). |
Knowledge Base
The adaptive scan engine reads JSON files from mcp-server/src/burpsuite_mcp/knowledge/. Each file declares contexts, server-side matchers, and optional craft guidance for dynamic payload generation. Add a new .json file to extend coverage; auto_probe picks it up at runtime. The full per-category breakdown lives in mcp-server/src/burpsuite_mcp/knowledge/_INDEX.md.

Credential-based privesc (Pacu class) out-of-scope per operator policy. |
Latest additions cover the gap surface most bug-bounty and red-team work hits in 2024–2026: cloud storage anonymous enumeration, serverless function URL discovery, K8s external exposure, mobile deep-link and WebView injection, archive extraction (Zip Slip) and argument injection (curl --upload-file, git ext::, ssh -oProxyCommand, …), GraphQL engine-specific attacks (Hasura admin-secret, Apollo APQ poisoning, federation _entities abuse, PostGraphile RLS bypass, Dgraph admin, Strawberry SDL leak).
Save-Finding Pipeline
Three phases enforced by the gate:
- Replay.
resend_with_modification(index)confirms the anomaly and records alogger_index. - Assess.
assess_finding(...)runs the 7-question gate (scope, reproducibility, impact, dedup, evidence, NEVER-SUBMIT, triager) and returnsREPORT/NEEDS MORE EVIDENCE/DO NOT REPORTplus a suggested confidence. - Save.
save_finding(...)persists if the gate passed. The Java extension hard-rejects calls without resolvable evidence, NEVER-SUBMIT classes withoutchain_with[], and timing/blind classes withoutreproductions[].
Operators can override individual gate questions with overrides=["q5_evidence:<reason>", ...] (audit-trailed), pass human_verified=True, or change engagement policy with set_program_policy. See .claude/skills/user-override.md.
