Changes in version 0.2.1.9000                      

                 Changes in version 0.2.1 (2026-03-17)                  

  - mcp_server() now ensures that inputSchema always includes a
    properties field, even for tools with no arguments (#91 by
    @itkonen).

  - mcp_server() now negotiates the protocol version with clients,
    supporting versions 2024-11-05 through 2025-11-25 (#92 by @itkonen).

                 Changes in version 0.2.0 (2025-10-29)                  

Server

  - mcp_server() now supports HTTP transport in addition to stdio. Use
    type = "http" to start an HTTP server, with optional host and port
    arguments. For now, the implementation is authless.

  - mcp_server() now formats tool results in the same way as ellmer (#78
    by @gadenbuie).

  - mcp_server() gains logical argument session_tools, allowing users to
    opt-out of presenting R session tools (that make it possible to
    communicate with mcp_session()s) to clients.

  - Several tightenings-up of the implementation:
    
      - JSON-RPC responses now retain an explicit id = NULL value,
        ensuring parse-error replies conform to the MCP specification.
      - mcp_tools() now sends and receives a "notifications/initialized"
        (#77 by @galachad).
      - The implementation now supports the 2025-06-18 protocol version,
        updated from 2024-11-05.

  - mcp_session() now invisibly returns the nanonext socket used for
    communicating with the server.

Client

  - Notably, mcp_tools() did not gain an implementation of the HTTP
    transport. Instead, we now recommend the mcp-remote tool for serving
    local MCP servers via the HTTP transport in the documentation.

  - mcp_tools() now errors more informatively when an MCP server process
    exits unexpectedly (#82).

                 Changes in version 0.1.1 (2025-09-08)                  

  - Addressed an issue in tests on r-devel-linux-x86_64-fedora-clang.

                 Changes in version 0.1.0 (2025-07-18)                  

  - Initial CRAN submission.

Before the initial release of the package, mcptools was called acquaint
and supplied a default set of tools from btw, currently a GitHub-only
package, when R was used as an MCP server. The direction of the
dependency has been reversed; to use the same functionality from before,
transition acquaint::mcp_server() to btw::btw_mcp_server() and
acquaint::mcp_session() to btw::btw_mcp_session().
