MCP OSINT Server
by abrahamhl

MCP OSINT Server

This is a Model Context Protocol (MCP) server that exposes powerful Open Source Intelligence (OSINT) tools to AI agents.

Why MCP?

The Model Context Protocol (MCP) allows AI agents like Claude and Gemini to access external tools in a standardized way. By exposing OSINT tools via MCP, AI agents can perform automated threat intelligence, vulnerability analysis, and digital forensics directly from their chat interfaces.

Tools Exposed

Tool

Description

Input

Output

sanctions_screen

Screen a name against EU sanctions lists

{ name: string, birth_year?: number }

{ matches: Array<{listed_name, score, reasons[]}>, total_screened: number }

cve_brief

Get prioritized vulnerability brief

{ watchlist?: string[], max_items?: number, lang?: 'en'|'nl'|'es' }

{ priorities: {act_now: [], this_week: [], watch: []}, generated_at: string }

evidence_verify

Verify evidence chain integrity

{ case_id: string, evidence_dir: string }

{ verified: boolean, chain_length: number, broken_links: string[] }

chronolocate_sun

Installation & Usage

  1. Build the server:

    pnpm install
    pnpm build
  2. Add to your AI Agent's configuration (e.g. claude_desktop_config.json):

    {
      "mcpServers": {
        "osint": {
          "command": "node",
          "args": ["/path/to/mcp-osint-server/dist/index.js"]
        }
      }
    }

Scope & Limitations

  • These tools are thin wrappers around underlying Python tools. The Python tools must be installed and accessible in the environment.

  • The server currently executes Python scripts as subprocesses without maintaining a long-lived Python environment.

    C2.7/5.0

    Scored across 5 tools

    Disambiguation4/5

    Each tool targets a distinct OSINT capability (sanctions screening, vulnerability brief, evidence verification, sun position, IOC search), with minimal overlap. The only potential confusion is between evidence_verify and chronolocate_sun (both verification-related), but they operate at different levels of abstraction.

    Naming Consistency3/5

    All names use snake_case, but the word order varies: sanctions_screen (noun+verb), cve_brief (noun+noun), evidence_verify (noun+verb), chronolocate_sun (verb+noun), ioc_search (noun+verb). There is no consistent verb_noun pattern, making it mixed but still readable.

    Tool Count5/5

    Five tools is within the ideal 3–15 range. Each addresses a distinct need without redundancy, making the set well-scoped for a focused OSINT toolkit.

    Completeness2/5

    For an OSINT server, the surface lacks many standard capabilities such as DNS/WHOIS lookups, domain/IP enrichment, social media search, and reverse image search. While it covers sanctions, CVE, IOC, and verification, these gaps will likely cause agent failures on common OSINT tasks.
