Apache Axis2/C

  What is it?
  -----------

  Apache Axis2/C is a web services framework written in C, for building and
  consuming JSON/REST and SOAP services. It is embeddable: the same engine runs
  as an Apache httpd module, inside a standalone server, or linked directly into
  an application binary.

  It is written in C with no runtime beyond libc and its transport dependencies,
  which makes it usable where a managed runtime is not an option: as a module in
  an existing Apache httpd deployment, in embedded and resource-constrained
  environments, and on Android, where the build produces a native library and
  services are linked statically into the host process.

  Features
  --------

    * JSON/REST services over HTTP/1.1 and HTTP/2, with a JSON reader and
      writer and a JSON-RPC message receiver.

    * Runs as an Apache httpd module, as a standalone HTTP server, or embedded
      in an application.

    * Android and other static-linking targets. Service functions are declared
      as weak symbols, so the framework compiles and links with no service
      implementation present and an application supplies strong implementations
      at link time. This is what allows services to be linked into a single
      native binary on platforms that do not load shared modules at runtime.
      configure detects an Android target and builds accordingly.

    * Model Context Protocol (MCP) support, so deployed services can be called
      as tools by an AI agent. Demonstrated in the financial-benchmark-service
      sample, with two transports: a JSON-RPC 2.0 stdio server for MCP clients
      that launch a subprocess, and an HTTP catalog endpoint that builds the
      tool list by walking the deployed services at request time. Tool
      descriptions, JSON Schema and the read-only, idempotent and destructive
      hints come from parameters in services.xml, so an existing service is
      exposed as an MCP tool by adding metadata rather than writing code.

    * SOAP 1.1 and SOAP 1.2, built on the AXIOM XML object model, with complete
      WS-Addressing 1.0 support and MTOM/XOP for binary attachments.

    * One-way (In-Only) and request-response (In-Out) messaging, synchronous or
      asynchronous.

    * A code generator that produces C stubs and skeletons from WSDL.

  As a project of the Apache Software Foundation, the developers aim to
  collaboratively develop and maintain a robust, commercial-grade,
  standards-based web services stack implementation with freely available
  source code.
