Common questions

Is MCP Maltego safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.0) reached the registry 5 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

mcp-maltego

Maltego OSINT for AI agents.

Run transforms and Machines, build and analyse link graphs, and hand the result back to Maltego as a native .mtgx , from Claude, Gemini, Codex, Copilot, Cursor or any MCP client.

mcp-maltego is a high-performance Model Context Protocol server that turns any AI agent into an expert Maltego operator. It runs real OSINT transforms, chains them into autonomous reconnaissance Machines, maintains an in-memory or graph database investigation state with full provenance, recommends next-best pivots, and synchronizes seamlessly with Maltego Desktop via native .mtgx files.

[!TIP]

Zero-Cost & No Commercial Maltego License Required: You do not need a paid Maltego Pro/XL plan or commercial API keys to start. mcp-maltego runs completely free out of the box, generating native .mtgx graphs compatible with the free Maltego Community Edition (CE) or Basic tier.

🏛️ Layered Architecture: From Zero-Cost Core to Full Platform

mcp-maltego is built in three decoupled layers so you can start instantly without cloud infrastructure or configuration overhead:

Layer	Component	Description & Cost
Layer 0: Zero-Cost Core	`mcp-maltego` CLI & Server	Instant execution (`npx mcp-maltego`). Generates and parses native `.mtgx` files for Maltego Community Edition (CE). Includes 33 zero-key built-in transforms (DoH, RDAP/WHOIS, crt.sh, ASN Cymru, CISA KEV, URLhaus, AlienVault OTX, URLscan, Mempool.space Bitcoin UTXO, CIOH wallet clustering, OFAC SDN crypto sanctions, VASP touchpoints) and dynamic community plugins (`@custom_transform`). 100% Free & Local.
Layer 1: Investigation Memory	Graph Memory & Copilot	Local deterministic case storage (`~/.maltego-mcp/graph.json`), entity fusion, step auditing, autonomous multi-round Machines, and `osint_investigate` copilot.
Layer 2: Advanced Platform	Web Console & CTI Vault	Interactive Web Dashboard (`maltegoctl dashboard`) with Web Worker acceleration and 4 spatial layouts (Organic, Hierarchical, Radial, Categorized), multi-dimensional filtering (edges, entities, continuous confidence, hops & live search), Impeccable vector rendering (canvas icons, confidence rings, Bézier curves), Universal Table Suite (compact/normal/expanded density toggles, pagination, expandable accordion detail cards), interactive multi-hop path tracing & blast radius inspection, Blockchain AML Ledger with mixer detection, strict multi-case isolation and modular scoping (global Topbar sync and focused module selector), secure case deletion and atomic graph purging, Categorized Accounts Vault (Social Networks, Underground Forums, Darknet Markets) with session cookies & Tor SOCKS5 routing, burner inboxes (Mail.tm + OTP extractor), Tor/Dark Web CTI feeds, and optional Azure Cosmos DB Gremlin clustering.

Key features

20 tools, portable to every model. Flat JSON schemas validated against Gemini's strict function-calling subset; variants grouped with an action parameter so agents are not flooded with tools.
45 real transforms out of the box. 33 without API keys (DNS over HTTPS, RDAP/WHOIS, CISA KEV active exploitation, Abuse.ch URLhaus malware, certificate transparency via crt.sh and CertSpotter, HackerTarget, urlscan.io, Shodan InternetDB, Team Cymru & RIPE Stat ASN/netblocks, Gravatar, GitHub profile details, AlienVault OTX threat pulses, multi-network profile lookup, Mempool.space Bitcoin UTXO transactions & inputs/outputs, Common-Input Ownership Heuristic (CIOH) clustering, OFAC SDN crypto sanctions check, VASP/Exchange touchpoints, parsing) and 12 provider transforms that switch on when you set a key: VirusTotal, Shodan, SecurityTrails, Censys, Hunter.io, Have I Been Pwned, GreyNoise and Tatum.
Community Extensibility Engine (`@custom_transform`). Drop custom Python transform files in ~/.maltego-mcp/plugins/ or ./plugins/ to immediately expose custom OSINT logic to LLMs without touching core code.
Your Maltego transforms too. Speaks the Maltego TRX/iTDS XML protocol, so an agent can run the same transforms you use in Maltego.
Machines. DomainRecon, InfrastructureRecon, EmailRecon, CompanyFootprint, PersonalFootprint, PersonaFootprint, CryptoFlowRecon, URLRecon, ThreatSweep, ASNToNetblocks and your own in TOML, with recursive rounds and cost budgets.
Cryptoforensics & Blockchain AML Traceability. Native ontology for cryptocurrency entities (maltego.CryptoCluster, maltego.VASPExchange, maltego.MixerContract, maltego.DeFiBridge), multi-hop transaction flow tracing, peeling chain and tumbler heuristics, OFAC SDN sanctions screening, and VASP deposit touchpoint detection.
Multi-Case Isolation & Modular Project Scoping. Synchronized global project selector in the Topbar and live graph, paired with decoupled per-module focus selectors (defaulting to [Follow Active Case]), strictly preventing cross-contamination between independent forensic cases.
Case Lifecycle & Atomic Purging. Safe, permanent removal of ad-hoc or temporary investigations with interactive confirmation, atomic deletion of entities and links from the graph store, local cache and evidence purging, and automated fallback to the next available case.
HUMINT, Breach Router & Multi-Agent Swarms. Native humint.* entity ontology (humint.Alias, humint.Organization, humint.LocationHistory, humint.PsychologicalTrait), cross-platform pseudonym correlation, subject behavioral profiling ([Hipótesis]), chronological anomaly detection, weighted relationships, a local SQLite
k-Anonymity/XposedOrNot breach router (BreachSemanticPivot), and multi-agent case fork/delegate/merge with optimistic locking.
An investigation copilot. osint_investigate does detection, case creation, the right Machine, scoring and recommendations in one call. Every step is remembered (what, on what, why, result), every entity has explainable provenance and a priority score, and next-best-action learns from how each transform performed.
Native Maltego round-trip. .mtgx export with hierarchical, radial or force-directed layout and the investigation memory embedded; .mtgx import; local transforms inside Maltego Desktop to open a case, expand neighbours and send entities back to the agents; import of your exact Maltego entity ontology.
Reports and CLI. Executive reports in Markdown or self-contained HTML, and maltegoctl for terminals and CI.
Safe by default. OSINT content is treated as untrusted data, XML is parsed with defusedxml, archives are read with bounds, agents cannot supply arbitrary URLs, and API keys are never logged.

Community Contributions & Governance

We welcome contributions! All contributions are subject to our Contributing Guide. Pull requests are automatically analyzed by our AST Security & Blast Radius CI scanner, and all merges require manual sign-off by repository owner @Data-Unix.

Requirements

Node.js 18 or newer (for npx).
uv — manages the Python 3.12 runtime automatically (if uv is not installed yet, mcp-maltego installs it automatically into ~/.maltego-mcp/bin on first run).

Prepare the runtime, ~/.maltego-mcp/.env template, Maltego Desktop bridge .mtz, and global CLI launchers (mcp-maltego, maltego-mcp, maltegoctl, maltego-mcp-bridge in ~/.local/bin / %USERPROFILE%\.local\bin added to your PATH) in one command:

npx -y mcp-maltego setup

You can also choose a specific deployment mode or client target on any OS / distribution (Windows PowerShell/CMD, macOS, Ubuntu/Debian, Kali, Fedora/RHEL, Arch, Alpine):

npx -y mcp-maltego setup --mode global              # (Default) Global CLI in ~/.local/bin + PATH (run from any directory)

npx -y mcp-maltego setup --mode local # Isolated inside ~/.maltego-mcp without modifying PATH npx -y mcp-maltego setup --mode http # Prepare + print Streamable HTTP server startup npx -y mcp-maltego setup --client claude # Print ready-to-use config for a specific client (claude|gemini|codex|copilot|cursor|all)

Getting started

Standard configuration, valid for most MCP clients:

"mcpServers": { "maltego": { "command": "npx", "args": ["-y", "mcp-maltego"] } } }

Then ask your agent:

Investigate example.com, give me the summary of the case and export it for Maltego.
