The Frontrun MCP Server gives AI agents real-time access to the Frontrun API for monitoring X (Twitter) accounts — primarily venture capitalists — to detect investment signals, follow trends, and analyze market activity.

frontrun_new_follows)Get the full current follow list for any tracked account (
frontrun_snapshot)Analyze a specific account's activity profile including follow velocity and sector distribution (

Signal Detection
Identify convergence signals — entities independently followed by multiple tracked accounts, indicating strong pre-funding interest (
frontrun_convergence)Get trending entities ranked by how many tracked accounts recently followed them (
frontrun_trending)
Search & Classification
Search discovered entities by sector, keyword, or type (startup, VC fund, accelerator, etc.) (
frontrun_search)Run AI classification on specific entities for sector and type labels (
frontrun_classify)Retrieve new follows with full AI + custom rule enrichment merged (
frontrun_enriched_follows)
Custom Rules & Tagging
Create, list, update, and delete custom classification rules that auto-tag entities based on bio keywords, sector, or username patterns (
frontrun_create_rule,frontrun_list_rules,frontrun_update_rule,frontrun_delete_rule)Add custom tags, sector overrides, or notes to specific entities for watchlists or competitor tracking (
frontrun_tag)List all custom-tagged entities, filterable by tag or sector (
