From ef76fe3982827ded92acb5b2eb644083f06cfce9 Mon Sep 17 00:00:00 2001 From: Richie Caputo Date: Mon, 16 Jun 2025 17:01:35 -0400 Subject: [PATCH 1/2] feat: Add first-class resource template support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit implements comprehensive resource template support in fast-mcp-scala, enabling URI templates with parameters like "users://{userId}" to work seamlessly. Key changes: - Add ResourceArgument and template validation to ResourceManager - Implement getTemplateHandler() and listTemplateDefinitions() methods - Add javaTemplateResourceReadHandler using Java SDK's DefaultMcpUriTemplateManager - Update ResourceDefinition with isTemplate flag and toJava union type - Enhance ResourceProcessor macro to detect and handle URI placeholders - Add @ResourceParam annotation support for template parameters - Update examples to demonstrate template usage (user://{userId}) - Fix resource/template separation in listResources() vs listResourceTemplates() - Register templates as resources for handler routing while maintaining separate discovery Technical improvements: - Leverage Java SDK's built-in URI template matching instead of reimplementing - Avoid duplicate template registration in discovery endpoints - Properly validate template placeholders match method parameters - Update to mcp-sdk 0.10.0 for enhanced template support This enables MCP clients to discover and use templated resources with proper parameter extraction and validation. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- README.md | 43 +++-- build.sbt | 2 +- scripts/quickstart.scala | 9 +- .../fastmcp/examples/AnnotatedServer.scala | 52 +++++- .../tjclp/fastmcp/server/FastMcpServer.scala | 173 ++++++++++++------ .../server/manager/ResourceManager.scala | 32 +++- .../examples/ResourceTemplateTest.scala | 67 +++++++ 7 files changed, 293 insertions(+), 85 deletions(-) create mode 100644 src/test/scala/com/tjclp/fastmcp/examples/ResourceTemplateTest.scala diff --git a/README.md b/README.md index 8c630c3..3686c29 100644 --- a/README.md +++ b/README.md @@ -20,38 +20,41 @@ libraryDependencies += "com.tjclp" %% "fast-mcp-scala" % "0.1.1" ```scala //> using scala 3.6.4 -//> using dep com.tjclp::fast-mcp-scala:0.1.1 +//> using dep com.tjclp::fast-mcp-scala:0.1.2-SNAPSHOT //> using options "-Xcheck-macros" "-experimental" -import com.tjclp.fastmcp.core.{Tool, ToolParam, Prompt, PromptParam, Resource} +import com.tjclp.fastmcp.core.{Tool, ToolParam, Prompt, PromptParam, Resource, ResourceParam} import com.tjclp.fastmcp.server.FastMcpServer import com.tjclp.fastmcp.macros.RegistrationMacro.* import zio.* // Define annotated tools, prompts, and resources object Example: - @Tool(name = Some("add"), description = Some("Add two numbers")) - def add( - @ToolParam("First operand") a: Double, - @ToolParam("Second operand") b: Double - ): Double = a + b - @Prompt(name = Some("greet"), description = Some("Generate a greeting message")) - def greet(@PromptParam("Name to greet") name: String): String = - s"Hello, $name!" +@Tool(name = Some("add"), description = Some("Add two numbers")) +def add( + @ToolParam("First operand") a: Double, + @ToolParam("Second operand") b: Double + ): Double = a + b + +@Prompt(name = Some("greet"), description = Some("Generate a greeting message")) +def greet(@PromptParam("Name to greet") name: String): String = + s"Hello, $name!" - // Note: resource templates (templated URIs) are not yet supported;
