Anthropic published the Model Context Protocol on 25 November 2024 as an open standard, and the first reference servers shipped the same day. Through 2025 the major AI clients added support, the protocol gained a remote transport, and hosted MCP servers became the normal way to give an assistant live data. JobsPipe runs one. ## When MCP servers came out and how the standard spread 1. **November 2024: the release.** Anthropic published the specification, SDKs in TypeScript and Python, and a set of open-source reference servers for local tools such as the filesystem, Git and databases, with Claude Desktop as the first client. From day one anyone could write a server and any client that implemented the protocol could call it. 2. **Early 2025: coding tools.** Editors and coding agents were the first wave of clients: Cursor, Windsurf, Zed, Claude Code and VS Code added MCP support over the first half of the year, in varying order and depth. Most early servers ran locally over standard input and output. 3. **March 2025 onward: the other labs.** OpenAI added MCP support to its Agents SDK in March 2025 and later to ChatGPT, and Google announced support in its Gemini tooling during 2025. The details differed by product, but the effect was that one server reached every major assistant. 4. **2025: remote servers.** A spec revision introduced the Streamable HTTP transport and an OAuth-based authorization flow, replacing the earlier server-sent-events arrangement. That made hosted servers practical, and vendors began running MCP endpoints at a URL rather than shipping a package to install. 5. **Late 2025: governance.** Anthropic announced it was donating MCP to a new foundation under the Linux Foundation, co-founded with OpenAI and Block, to hold the specification under neutral stewardship. Development continues in the open on GitHub. 6. **Where it stands.** Registries list servers by the thousand, clients prompt the user before each tool call, and the open question has moved from whether a client supports MCP to which servers are worth connecting. For a searcher the practical answer is that MCP servers have existed since late 2024 and have been usable from mainstream clients since 2025, so a server written today has a client on every side. How one is built and what it exposes is in [what is an MCP server](/blog/what-is-an-mcp-server), and the protocol in the context of AI tooling is in [what is MCP in AI](/answers/what-is-mcp-in-ai). Dates for individual client releases shifted as products moved from preview to general availability, so treat the sequence above as the order of events rather than a precise calendar. ## Where JobsPipe fits JobsPipe is a jobs data API that collects live postings from LinkedIn, Indeed, Y Combinator, Naukri, Workday, Greenhouse, Workable, SmartRecruiters, Ashby, Lever and Paylocity, returns them as one schema with closure tracking and a ghost score, and includes a free tier of 1,000 jobs a month. Its hosted MCP server at `https://mcp.jobspipe.dev/mcp` uses the Streamable HTTP transport and exposes four tools: `search_jobs`, `detect_company_tech_stack`, `list_pricing_plans` and `search_documentation`. Connecting it to Claude Code is one command: ``` claude mcp add --transport http jobspipe https://mcp.jobspipe.dev/mcp ``` Other clients take a JSON entry naming the same URL, and the client-by-client setup is on the [MCP server page](/mcp-server). Coding agents can also read `/agents.md` on jobspipe.dev for the setup without a person in the loop. Connect a hosted MCP server that has been live since 2025 - free tier included. ![](/listly/shape-heart.png) FAQs ## Frequently Asked Questions ### Who created MCP? Anthropic created the Model Context Protocol and published it on 25 November 2024 with a specification, SDKs and reference servers. In late 2025 Anthropic announced it was moving the protocol into a foundation under the Linux Foundation, co-founded with OpenAI and Block, so stewardship is now shared rather than held by one vendor. ### Is MCP an open standard? Yes. The specification and the SDKs are open source, anyone can implement a client or a server without a licence, and the protocol is developed in public on GitHub. The move to a Linux Foundation project in late 2025 formalised that neutrality. Hosted servers such as JobsPipe's are ordinary implementations of the same public spec. ### Which apps support MCP? Claude Desktop, Claude Code and claude.ai connectors; coding tools including Cursor, Windsurf, Zed and VS Code; OpenAI's Agents SDK and ChatGPT; and agent frameworks that embed an MCP client. Support arrived at different times through 2025 and varies in depth, so check whether a given client handles remote Streamable HTTP servers and authorization.
