Our reading of Clear Line Ops, from the data
Clear Line Ops is a science & research MCP server from mfarrell628, listed in the official MCP Registry.
Its 127 tools add about 26,772 tokens to every model turn, heavier than the science & research median of 2,616 tokens across 126 measured servers (measured 2026-10-19).
Maintenance is active: the last public signal was 4 days ago (2026-10-14). For comparison, 73% of science & research servers are active or maintained.
With 0 GitHub stars it ranks #442 of 1,435 science & research servers we index.
It runs as a hosted endpoint, so there is nothing to install.

Layouts: 'dashboard' (sidebar, animated KPI cards, live chart, searchable sortable table), 'crud' (a full create/edit/delete data manager for any record type with modal forms), 'chat' (an AI-chat style interface with typing indicator). Themes: glass (frosted, gradient), neon (terminal glow), paper (warm editorial), brutal (bold neo-brutalist). Includes dark/light mode, mobile drawer navigation and accessible controls. Runs on sample data out of the box and connects to your real API with api_base_url (crud: GET/POST/PUT/DE
site_create1,067 tokCreate a complete, responsive, animated website from a short brief and host it instantly. Pick sections (hero, features, stats, about, pricing, testimonials, faq, gallery, contact, cta), a style and an accent colour. Includes dark mode, mobile menu, scroll reveals, count-up stats, monthly/yearly pricing toggle, FAQ accordion, validated contact form, SEO tags, favicon, robots.txt and sitemap. Returns a site_id and a live URL once published. Edit afterwards with site_files and redeploy with site_deploy. Sites are served in a sandbox, so avoid code that needs cookies or cross-origin storage. Cost
arch_review816 tokScreen an existing project for weaknesses and improvements. Provide whatever you have: beams [{name, span_m, width_mm, depth_mm, material (timber|steel|concrete|lvl), tributary_width_m}], columns [{name, load_kn, width_mm, depth_mm, height_m, material}], rooms [{name, area_m2, windows_m2, egress_window, ventilation, occupants}], floors, floor_height_m, exits, corridor_width_m, stair_width_m, ceiling_height_m, structure, sprinklers, r_value, seismic_zone/wind_zone ('high'), bracing, soft_storey, dead_load_kpa, live_load_kpa, and optionally dxf (text of a DXF plan). Returns a score, prioritised
hub_setup579 tokCreate a workspace that links your apps and agents so they can talk to each other. Pick a template or list apps and routes yourself. Every app gets a private inbound URL: any tool that can POST JSON to it sends events into the workspace, and routes forward those events to other apps (Slack, Discord, any https webhook, or an agent inbox that AI agents read with hub_read). Templates: 'chat_alerts' (send alerts from anything into Slack/Discord), 'agent_team' (give each agent an inbox and let them message one another), 'webhook_relay' (receive events and forward them to another service), 'blank'.

Query public open data by layer or combine several: drug incidents, overdose deaths, homicides, suicides (anonymised), human trafficking, prostitution, sex offences, Seattle narcotics 911 calls, SAMHSA treatment sites and CDC state overdose trends. Use layer for one, or layers for several at once. Filter by date range, keyword and map box. Set refresh=true to re-pull live from the source agencies instead of the hourly cache. Returns points plus ranked hotspots. Data is public, may lag, and shows reported incidents, not guilt. Cost: 3 credits per call.

Security signals
97/100 — no known issues found as of 2026-10-19, from the checks below. This is not a guarantee of safety; review what a server can do before connecting it.
Deductions
- No security policy (SECURITY.md)-3
Checks
- ✓Repository hygiene (archived, activity, license, security policy)
- ✓Tool descriptions (prompt-injection and hidden-text heuristics)
- ○Package metadata (install scripts, provenance) — pending
- ○Source scan (secrets, CVEs, risky code) by vectra-guard — pending
Scan it yourself before installing with vectra-guard, the open-source agent security CLI. Scoring rules
