recon
Public DNS, certificate transparency, and identity observations.
Installation
Ajoutez ceci à la configuration MCP de votre client (Claude Desktop : claude_desktop_config.json ; Cursor : .cursor/mcp.json ; VS Code et les autres utilisent la même forme « mcpServers »).

{
"mcpServers": {
"recon": {
"command": "uvx",
"args": [
"recon-tool==2.27.0",
"mcp"
]
}
}

Sommaire
recon
Point recon at a domain to see its public technology and identity footprint: email providers and controls, identity indicators, SaaS services, and cloud infrastructure. No credentials, API keys, or active scanning. Use the CLI for a quick lookup, versioned JSON for automation, or the local MCP server from an agent.
recon reports evidence-backed observations, not a complete inventory or a security verdict. A domain does not establish an organization's boundaries.
See the Output
Synthetic illustration, generated, not captured. The real formatter renders
a deterministic, no-network fixture for Example Industries Ltd. No real
organization is depicted, and no live lookup of reserved example.com
reproduces this fixture.

Quick Start
macOS / Linux:
curl -fsSL https://raw.githubusercontent.com/blisspixel/recon/main/scripts/install.sh | bash
Windows (PowerShell):
powershell -NoProfile -ExecutionPolicy Bypass -Command "irm https://raw.githubusercontent.com/blisspixel/recon/main/scripts/install.ps1 | iex"
The installer sets up recon for your user account, including Python when needed.
Open a new terminal afterward. Python 3.15 is the default development and release
runtime; 3.11 through 3.15 remain supported. Already have a supported Python? Use
pip install recon-tool in a virtual environment, or uv tool install --python 3.15 recon-tool /
pipx install --python python3.15 recon-tool on managed distributions like Arch Linux and Omarchy.
For review-before-run instructions, other package managers, updates, and recovery,
see the installation guide.
recon --version # offline install check
recon doctor # online connectivity and installation diagnostics
Lookups make DNS queries visible to recursive and authoritative infrastructure.
MTA-STS is the only default target-owned HTTP request; Google CSE and BIMI
certificate probes require explicit --direct-probes. There is no port
scanning or application crawling. Replace the placeholder to start:
recon "<domain-you-want-to-review>"
Ordinary lookups may reuse the 24-hour result cache and say so when they do; a
result whose collection had unavailable sources is never reused. Use
--no-cache to bypass the cache for both reading and writing;
certificate-transparency enrichment has a separate cache. See
first lookup and cache behavior.
Common Commands
The bare command stays compact. Request evidence or structured output when needed:
recon example.com # compact panel
recon example.com --explain # evidence and source status
recon example.com --json # structured record
recon example.com --plain # linear text for screen readers and grep
recon review example.com # fresh, evidence-linked review bundle
recon batch domains.txt --json # look up a supplied domain list
recon delta example.com # compare with a cached baseline
recon update # update through the original package manager
These examples use reserved domains; real lookups will not reproduce the synthetic illustration above. For multi-domain reviews, recon describes observed similarities and differences without inferring ownership or a corporate relationship. See the evidence-first review workflow and batch guide.
Use with an Agent
The PyPI package installs the CLI and MCP runtime. Connect the local server to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, or Kiro:
recon mcp install --client=claude-desktop
recon mcp doctor
Restart the client and begin with manual tool approvals. Ask for one domain's email and identity indicators, or a service comparison across supplied domains. Missing evidence means "not observed", not "not used"; collection failures remain explicit. Local execution is the default, and the project does not operate a hosted service.
See MCP setup and supported clients and skills, plugins, and their validation status.
Omarchy Desktop Shell Integration
recon includes a thin, keyboard-first desktop shell plugin for Omarchy
located in integrations/omarchy/:
- Keyboard-driven workflow: focus domain input automatically, press
Enterto run bounded inspection, and pressCtrl+Dto toggle baseline delta comparison. - Direct process invocation: passes structured arguments directly (
["recon", domain, "--json"]) without shell interpolation. - Safe clipboard handling: pasting text never triggers an automatic network request.
- Zero background daemons: runs unprivileged inside Omarchy's Quickshell environment.
See integrations/omarchy/README.md for installation and shortcuts.

Contributing and Support
Catalog corrections and documented vendor patterns are especially useful. Start with CONTRIBUTING.md for setup, verification, and contribution requirements; coding agents should also read AGENTS.md. For repeatable catalog work, start with the harness-neutral maintenance skill and offline example.
Use issues for bugs and feature requests. Keep public examples reserved and synthetic; never post evaluated company domains, tenant IDs, or per-domain results. See the private reporting paths and security policy. Intended for defensive use.

Questions fréquentes
Qu'est-ce que recon ?
Public DNS, certificate transparency, and identity observations.
Comment installer recon ?
Il s'exécute sur votre machine. Dans Claude Code : claude mcp add recon -- uvx recon-tool==2.27.0 mcp. Pour les autres clients, collez la configuration JSON de cette page dans leurs réglages MCP.
Faut-il une clé API pour recon ?
Son entrée au registre n'indique aucune clé ni secret obligatoire. Certaines fonctions peuvent tout de même demander un compte auprès du service auquel il se connecte.
recon est-il open source ?
Oui. Son code est sur GitHub sous licence Apache-2.0.
Qui maintient recon ?
Il est publié par blisspixel. AI.tn le référence sans le maintenir ni le recommander.
Issu du registre MCP officiel. Être listé n'est pas une recommandation : vérifiez le code et les permissions d'un serveur avant de lui donner accès à vos données.
