Five days since the last pulse. 232 new servers push the registry from 2,889 to 3,121. Zero removed. The headline numbers are stable — average score holds at 48.4, median at 52 — but the composition is shifting. A third of the registry now declares streamable-HTTP transport. Agent payment infrastructure appeared in force. And the most niche MCP suite yet arrived: ten servers for amateur radio.

168 of 232 new entries landed in Low Trust. That's 72% — consistent with the pattern of new servers arriving with fresh repos and limited community signals. Scores will rise as projects mature.
The New Number
Kubeshark (io.github.kubeshark/mcp) is the only new High Trust entry. 11,810 stars, 519 forks, Apache-2.0 licensed, active for years. It provides real-time Kubernetes network traffic visibility — HTTP, gRPC, Redis, Kafka, DNS analysis. Score: 84. Another established project choosing MCP as a distribution channel, following the Scrapling pattern from last week.
Transport Shift
The registry's transport mix has changed dramatically. Streamable-HTTP — the newer transport that replaces SSE for remote MCP servers — now accounts for 1,059 servers (34%) of the registry. Of the 232 new servers this batch, 70 (30%) chose streamable-HTTP. More striking: 897 servers across the registry use streamable-HTTP with no stdio fallback at all. SSE lingers at 193 servers (6%). The transition is underway. Full analysis →
The Agent Economy
Roughly 25 new servers deal with agent payments and commerce — escrow contracts, USDC payment rails, agent wallets, pay-per-call pricing, and A2A marketplaces. This is the largest single-batch arrival of payment infrastructure we've seen. Notable entries include agora402 and paycrow (USDC escrow on Base), clawvault (spending limits and human approval for agent wallets), agoragentic (A2A service marketplace), and the harvey- suite (four servers with per-call USDC pricing).

Niche Expansion
The batch that keeps MCP weird:
- qso-graph — 10 amateur radio servers. ADIF log parsing, eQSL verification, LOTW tracking, Parks on the Air, Summits on the Air, WSPR propagation, solar weather, callsign lookup. The most complete niche suite ever registered. Spotlight →
- mansurjisan — 6 earth science servers. GOES satellite imagery, hurricane reconnaissance, wave forecasts, USGS streamflow, ocean model debuggers. Operational science tooling. Spotlight →
- rftools — 197 RF and electronics calculators. Microstrip, link budget, filters, power. Score: 57.
- tablafocus — Tabla learning: glossary, taals, composition, practice coaching, certification prep. Score: 59.
- alfanous — Qur'an search with Arabic text, transliteration, and advanced search. Score: 70.
Microsoft and Azure
Microsoft added four entries this batch. Azure/containerization-assist (score 73) provides AI-powered containerization workflows with Docker and Kubernetes support. microsoft/awesome-copilot (score 79) stores Copilot customizations from the Awesome Copilot repository. agent365-mailtools (score 32) adds email tools. dotnet-template-mcp (score 56) lets agents search, inspect, and create .NET projects from templates. Microsoft's MCP footprint is growing.
Notable New Entries
- SEC Intelligence — Insider sentiment, material events, financial ratios, disclosure search. Built on edgartools (1,798 stars). Streamable-HTTP only. Score: 71.
- Pyth Network — Real-time price feeds for 500+ crypto, equities, FX, and commodities. Score: 71.
- Alfanous — Qur'an search engine with advanced Arabic support. Score: 70.
- mcp-outline — Connect AI assistants to Outline for document management. Score: 68.
- NodeBench — 260 tools across 49 domains. Score: 65.
- Shodan + VirusTotal — Two cybersecurity reconnaissance servers from one developer. Scores: 63–64.
- Evidra — Fail-closed policy guardrails for agents running kubectl, terraform, helm. Score: 55.
What to Watch
- Streamable-HTTP is the new default. A third of the registry has adopted it. New remote-first servers are skipping SSE entirely. The protocol is moving past its stdio-only origins.
- Payment rails are arriving before demand. 25 payment-related servers in one batch — escrow, wallets, marketplaces — but the autonomous agents that need them are still emerging. The infrastructure is ahead of the use case. That's either prescient or premature.
- Domain specificity keeps deepening. Ham radio, tabla, RF engineering, hurricane reconnaissance, Bulgarian pensions. MCP's original audience was developers. The registry is now serving communities that have never written an API integration.
- Established projects keep choosing MCP. Kubeshark (11.8k stars), edgartools (1.8k stars), Pyth Network — mature projects adding MCP as an interface. This is the adoption pattern that matters most.
