MCP's growth since the December 2025 Linux Foundation donation, measured against live registries: SDK downloads roughly 5x'd in nine months (npm SDK 38.5M→204M monthly; PyPI's mcp adds 319M), registries list 11,000–23,000 servers depending on curation bar, and the AAIF has grown from 49 founding-day members to 247. Every count dated and sourced.
Key takeaways
- At donation (December 9, 2025): 97M+ monthly SDK downloads and ~10,000 active servers — the official baseline numbers from Anthropic and the Linux Foundation.
- Nine months later: the npm TypeScript SDK alone tops 200M monthly downloads (5x its December rate) and PyPI's mcp package adds ~319M — and the project itself now cites close to half a billion a month across its Tier 1 SDKs, with TypeScript and Python each past 1B lifetime.
- Server counts depend on the registry's bar: Smithery lists ~11,200, PulseMCP tracks ~22,000, mcp.so self-reported ~23,000 (July) — cite the registry with the number, never a bare 'there are X servers.'
- Governance is genuinely multi-vendor now: the Agentic AI Foundation's eight Platinum members include Anthropic, OpenAI, Google, Microsoft, AWS, and Block, and total membership reached 247 in August 2026 (up from 49 at launch).
- The reference monorepo (modelcontextprotocol/servers) sits at ~90k GitHub stars — top-thousandth-percentile open source — with first-class client support across ChatGPT, Claude, Cursor, Gemini, Copilot, and VS Code.
MCP went from Anthropic side-project (November 2024) to Linux Foundation standard (December 2025) to — by mid-2026 — infrastructure whose download counts resemble a major package ecosystem. The numbers below are pulled live from registries and primary announcements, dated September 1, 2026, and refreshed on a cadence; circulating figures we couldn't trace are omitted.
The baseline: donation day (December 9, 2025)
From the Anthropic and Linux Foundation announcements (primary):
- 97M+ monthly SDK downloads across the official SDKs
- ~10,000 active/published MCP servers
- First-class client support named at donation: ChatGPT, Claude, Cursor, Gemini, Microsoft Copilot, VS Code
- The Agentic AI Foundation launched with founding projects MCP, goose (Block), and AGENTS.md (OpenAI — itself in 60,000+ open-source projects), and founding members AWS, Anthropic, Block, Bloomberg, Cloudflare, Google, Microsoft, OpenAI
Nine months later: the growth curve
Measured directly from registry APIs, September 1, 2026 (primary):
| Metric | Dec 2025 | Sep 2026 | Source |
|---|---|---|---|
npm @modelcontextprotocol/sdk, monthly downloads | 38.5M | ~204M | npm registry API |
PyPI mcp package, monthly downloads | — | ~319M | pypistats |
PyPI fastmcp, monthly downloads | — | ~85M (down from ~93M in July) | pypistats |
| Combined core SDKs | ~97M (all SDKs, official figure) | ~523M (npm+PyPI core alone) | computed |
Roughly a 5x rise in nine months on the cleanest comparable series — and since the September figure counts only the two core packages, it understates the total. The project's own accounting agrees: the July 28, 2026 spec-release post cites "close to half-a-billion downloads a month" across Tier 1 SDKs, with the TypeScript and Python SDKs each past 1 billion lifetime downloads (primary). One wrinkle: fastmcp, the popular Python framework, dipped from ~93M to ~85M over the summer — growth is concentrating in the core packages.
How many servers? Name the registry
| Registry | Servers (Sep 1, 2026) | Bar |
|---|---|---|
| Smithery | 11,245 | Registry (API totalCount); up from 6,652 in July |
| PulseMCP | 21,982 | Broad daily-updated tracker |
| mcp.so | ~23,000 (Jul 1, 2026; site blocks automated re-checks) | Self-reported directory count |
The spread is the lesson: "how many MCP servers exist" has no single answer — curation bars still differ by 2x — so any citation should name its registry. (The official registry exposes no public total; we don't quote one.) What the spread agrees on: supply outgrew discovery, which is why the shortlist matters more than the catalog and governance became its own discipline.
Ecosystem signals
- modelcontextprotocol/servers: ~90,000 GitHub stars; the Python SDK ~24,200, TypeScript SDK ~13,300, spec repo ~9,100 (GitHub API, primary).
- AAIF membership beyond the founding eight: 18 Gold members at launch (including Cisco, Datadog, Docker, IBM, JetBrains, Oracle, Salesforce, SAP, Shopify, Snowflake) and 23 Silver (including Hugging Face, Uber, Zapier, Pydantic, Elastic), since expanded to 190 (May 18, 2026) and 247 total members (August 13, 2026 — 57 new: 3 Gold, 33 Silver, 21 Associate) (Linux Foundation, primary). Platinum stays capped at the founding eight.
- The protocol's sibling under the same roof: A2A for agent-to-agent, donated by Google in mid-2025 — both halves of the agent stack now sit in neutral governance.
The arc these numbers trace: MCP won the agent-to-tool layer the way standards win — not by mandate but by default-ness, until "does it speak MCP" stopped being a question. The practical guides for living in that ecosystem: adding servers to Claude Code and the 2026 server shortlist.
Frequently asked questions
- How many MCP servers exist in 2026?
- Between ~11,000 and ~23,000, depending on who's counting and how: Smithery's registry lists 11,245 and PulseMCP tracks 21,982 (both September 1, 2026); mcp.so self-reported ~23,000 as of July 1 (the site blocks automated re-checks). The official line at the December 2025 donation was 'over 10,000 published servers.' The honest answer names the registry; the practical answer is that discovery, not supply, is the constraint.
- How fast is MCP growing?
- The cleanest series is SDK downloads: at donation (December 2025) the project cited 97M monthly across SDKs; by September 2026 the npm TypeScript SDK alone runs ~204M/month (vs 38.5M in December) and PyPI's mcp package ~319M/month — roughly 5x in nine months, measured directly from registry APIs. The project's own July 28, 2026 spec-release post put Tier 1 SDK downloads at close to half a billion a month.
- Who controls MCP now?
- The Agentic AI Foundation under the Linux Foundation, since December 9, 2025 — co-founded by Anthropic (donating MCP), Block (goose), and OpenAI (AGENTS.md), with AWS, Bloomberg, Cloudflare, Google, and Microsoft completing the founding eight, plus 41 gold/silver members at launch (Cisco to Hugging Face), a roster since grown to 247 (August 2026). Anthropic stated maintainers and governance processes carried over unchanged.
