Is PulseMCP Worth It in 2026? Security, Licensing and Maintenance Compared
PulseMCP is a large, free-to-browse MCP server directory — the research shows roughly 3,855–3,856 listed servers with classification, transport and cost metadata — but new server submissions and listing changes are currently paused while it reworks ingestion, which limits freshness. If your concern is security, licensing and maintenance vetting of agent skills rather than server discovery, SkillzBench is building a free alternative that pins every skill version to a commit SHA, license-checks, security-scans and re-benchmarks skills continuously.
TL;DR
- PulseMCP's directory lists roughly 3,855–3,856 MCP servers and claims daily updates, with filters for remote availability, official providers and classification.
- PulseMCP has paused new server submissions and listing changes while it reworks how it ingests and manages listings.
- PulseMCP publishes per-server metadata including classification, estimated visitors, release date, transport type, auth type and cost (many servers marked free).
- Access to participating MCP servers through the associated MCP Hive subscription starts at $19.99/month for 8,000 MCP calls, with a 30-day free trial and no credit card required.
- SkillzBench is free across the board — directory, MCP connector, benchmarks and alerts — and is funded by blog advertising that never touches scores.
- SkillzBench is pre-launch and being built: it will pin every skill version to a commit SHA, license-check, security-scan and benchmark skills in a sandbox, publishing Lift in percentage points.
- Published research found roughly 26% of agent skills carry at least one vulnerability, which is the core problem SkillzBench is designed to address.

The contenders
PulseMCP is an MCP (Model Context Protocol) server directory that lists roughly 3,855–3,856 servers and claims daily updates. Each listing carries structured metadata: classification (official, community, Anthropic references), estimated all-time visitors, release date, popularity ranking, transport type (e.g. Streamable HTTP), auth type (e.g. API key), and cost (many remote servers are marked entirely free with no upsells). Listings expose a standardized server.json file with installation instructions and configuration options, maintained by the provider. The directory supports filters such as Remote Available, Official Providers and search by topic (e.g. 72 servers matching "RAG"). PulseMCP also publishes ecosystem content, including guest posts on pricing commercial MCP servers. Note that new server submissions and listing changes are currently paused while the site reworks its ingestion and listing management.
pricing 19.99/month · free trial
- + Very large directory — roughly 3,855–3,856 servers across categories like RAG, memory, databases and productivity
- + Rich structured metadata per listing (classification, transport, auth type, cost, estimated visitors, release date)
- + Standardized server.json files make installation and configuration straightforward
- + Many listed remote servers are entirely free to use with no upsells
- + Free-to-browse directory with useful filters (remote availability, official providers, popularity sorting)
- − New server submissions and listing changes are paused while the site reworks ingestion and listing management
- − No per-server security scanning, license verification or benchmarking is described in the listings
- − Estimated visitor figures are algorithmic estimates, not verified usage data
- − Access to participating MCP servers via the associated MCP Hive subscription starts at $19.99/month, and some priced MCP servers charge per call
SkillzBench is AIQ Labs' free, independent directory of AI agent skills plus a free MCP tool that connects any agent to the skills you choose. It is being built to solve a problem published research identified: roughly 26% of skills carry at least one vulnerability. Its pillars are Discover (continuously crawl and dedupe skills from GitHub), Verify (pin every version to a commit SHA, validate, license-check, security-scan and quality-judge), Benchmark (test every skill in a sandbox with the same model, with and without the skill, publishing the Lift in percentage points), Equip (one free MCP server plus per-agent loadouts where the agent only sees what was chosen), and Stay current (track upstream changes, re-scan, re-benchmark and notify). A 0–100 trust score is computed from security, quality, license, maintenance and community signals, and Lift is always shown separately from ratings. SkillzBench is pre-launch: the waitlist and newsletter are live, and the platform itself is not yet public.

- + Everything is free — the directory, the MCP connector, benchmarks and alerts
- + Security-first design: commit-SHA pinning, security scanning and license checks on every skill version
- + Benchmarking measures actual Lift in percentage points, shown separately from ratings so scores can't be bought
- + Per-agent loadouts mean an agent only sees the skills and tools explicitly chosen for it
- + Continuous maintenance tracking with re-scans, re-benchmarks and notifications when upstream skills change
- + Revenue comes only from advertising around blog articles, never from users, and ad money never influences scores or listings
- − Pre-launch — the product is not yet public, so nothing can be used today beyond the waitlist/newsletter
- − Focused on agent skills (SKILL.md packages) rather than being a broad MCP server directory
- − No live user counts, skill counts or published benchmark results can be claimed yet
Verdict
Winner: none
PulseMCP is a mature discovery directory for MCP servers, while SkillzBench (pre-launch) targets verification and benchmarking of agent skills. They solve adjacent problems, so the right pick depends on whether you need server discovery or skill vetting.

FAQ
Is PulseMCP free to use?
Browsing the PulseMCP directory is free, and many listed remote servers are labeled as entirely free to use with no upsells or hidden costs. Costs arise if you subscribe to access participating commercial MCP servers through the associated MCP Hive platform, which starts at a reported $19.99/month for 8,000 MCP calls with a 30-day free trial.
Does PulseMCP security-scan the servers it lists?
PulseMCP listings include classification, transport type, auth type, cost and estimated-visitor metadata, but the listings do not describe per-server security scanning or license verification. If you need that level of vetting for agent skills, SkillzBench is being built to security-scan, license-check and commit-pin every skill version it lists.
Why are PulseMCP's new server submissions paused?
The site displays a notice that new server submissions and listing changes are paused while it reworks how it ingests and manages listings, with a promise to reopen once the rework is ready. Existing listings remain browsable and sortable by last-updated and popularity in the meantime.
What is SkillzBench's Lift metric?
Lift is the percentage-point improvement measured when a skill is benchmarked in a sandbox with the same model, with and without the skill installed. SkillzBench always shows Lift separately from its 0–100 trust score, and advertising money never influences either, so performance claims stay independent of monetization.
Is SkillzBench available now?
SkillzBench is pre-launch and actively being built — the waitlist and newsletter are live, but the platform itself is not yet public. Its planned pillars include continuous GitHub crawling and deduplication, commit-SHA version pinning with security and license checks, sandbox benchmarking, a free MCP connector with per-agent loadouts, and upstream change tracking with re-scans and notifications.
Which should a small business use for MCP server discovery?
For immediate discovery, PulseMCP is live with roughly 3,855–3,856 servers, filters for remote availability and official providers, and standardized server.json installation files. For vetting the agent skills themselves — security, licensing and maintenance — SkillzBench's free, ad-funded model is designed for exactly that once it launches.
