+
+The MCP Server starter exposes Camel routes registered via the `ai-tool`
+component as tools of a Model Context Protocol (MCP) server, served through
+the Spring AI MCP server over streamable HTTP. No route is needed for the
+server itself: add the starter, tag the `ai-tool` routes to expose, and any
+MCP client (another Camel application, an IDE, a coding agent) can discover
+and call them.
+
+Tool semantics — tag-based opt-in (the untagged default pool is never
+exposed), flat-namespace collision refusal, per-call timeout and error
+sanitization — are owned by the runtime-agnostic `camel-mcp-server-api`
+bridge and are identical on every Camel runtime. Serving concerns (endpoint
+path, protocol, server identity, authentication) are owned by the Spring AI
+MCP server and configured via `spring.ai.mcp.server.*`; use
+`spring.ai.mcp.server.protocol=STREAMABLE` for the streamable HTTP transport.
+
+== Maven coordinates
+
+[source,xml]
+----
+
+ org.apache.camel.springboot
+ camel-mcp-server-starter
+
+----
+
+== Usage
+
+Define tools as regular `ai-tool` routes and give them tags:
+
+[source,java]
+----
+from("ai-tool:query_db?tags=crm&description=Query customer database"
+ + "¶meter.customerId=string¶meter.customerId.required=true")
+ .to("jdbc:dataSource");
+----
+
+or in YAML DSL:
+
+[source,yaml]
+----
+- route:
+ from:
+ uri: "ai-tool:send_email"
+ parameters:
+ description: "Send email notification"
+ tags: "notify"
+ parameter.to: string
+ parameter.to.description: "Recipient address"
+ parameter.to.required: "true"
+ parameter.subject: string
+ parameter.priority: string
+ parameter.priority.enum: "low,normal,high"
+ steps:
+ - to: "smtp://mail.example.com"
+----
+
+Tool parameters are declared with the `parameter.NAME` options: the value is
+the JSON type (`string`, `integer`, `number`, `boolean`), and the
+`parameter.NAME.description`, `parameter.NAME.required` and
+`parameter.NAME.enum` options refine the generated JSON Schema. Arguments
+arrive as message headers in the route (`${header.customerId}`).
+
+Select the tags to expose in `application.properties`:
+
+[source,properties]
+----
+camel.mcp-server.tags = crm,notify
+
+# per-call execution timeout (milliseconds, default 20000)
+camel.mcp-server.tool-timeout = 10000
+----
+
+The streamable HTTP transport has to be selected explicitly with
+`spring.ai.mcp.server.protocol=STREAMABLE`; when the property is not set,
+Spring AI serves the deprecated SSE transport instead and there is no
+endpoint at `/mcp`.
+
+Serving concerns are configured on the Spring AI MCP server — see the
+https://docs.spring.io/spring-ai/reference/api/mcp/mcp-streamable-http-server-boot-starter-docs.html[Spring AI MCP server documentation]
+for the full list of `spring.ai.mcp.server.*` options. For example:
+
+[source,properties]
+----
+spring.ai.mcp.server.protocol = STREAMABLE
+spring.ai.mcp.server.name = my-integration-app
+spring.ai.mcp.server.version = 1.0.0
+spring.ai.mcp.server.streamable-http.mcp-endpoint = /mcp
+----
+
+=== Connecting MCP clients
+
+Any MCP client can connect over streamable HTTP. Another Camel integration
+can consume the tools with the camel-openai MCP client and automatic tool
+execution:
+
+[source,java]
+----
+from("direct:agent")
+ .to("openai:chat-completion"
+ + "?model={{llm.model}}"
+ + "&autoToolExecution=true"
+ + "&mcpServer.myCamelTools.transportType=streamableHttp"
+ + "&mcpServer.myCamelTools.url=http://localhost:8080/mcp");
+----
+
+A coding agent or IDE is configured with the same URL, e.g. in an
+`mcp.json`-style client configuration:
+
+[source,json]
+----
+{
+ "mcpServers": {
+ "my-integration-app": {
+ "type": "http",
+ "url": "http://localhost:8080/mcp"
+ }
+ }
+}
+----
+
+=== Serving over stdio
+
+Out of the box the tools are served over streamable HTTP: the starter brings
+in `spring-ai-starter-mcp-server-webmvc`. MCP clients that launch the server
+as a subprocess speak over stdin/stdout instead, which Spring AI serves with
+the plain `spring-ai-starter-mcp-server`. Swap the transport starter:
+
+[source,xml]
+----
+
+ org.apache.camel.springboot
+ camel-mcp-server-starter
+
+
+ org.springframework.ai
+ spring-ai-starter-mcp-server-webmvc
+
+
+
+
+ org.springframework.ai
+ spring-ai-starter-mcp-server
+ 2.0.0
+
+----
+
+and enable the stdio transport:
+
+[source,properties]
+----
+spring.ai.mcp.server.stdio = true
+spring.main.web-application-type = none
+spring.main.banner-mode = off
+
+# stdout carries the MCP protocol, so nothing else may be written to it
+logging.threshold.console = OFF
+logging.file.name = my-integration-app.log
+----
+
+Because stdout carries the MCP protocol, the application must not run as a
+web application, the banner has to be switched off and console logging has
+to be turned off — writing the log to a file instead. Leaving console
+logging on corrupts the protocol stream, as the Spring Boot startup log is
+then interleaved with the JSON-RPC messages.
+
+A stdio server is launched by the client instead of being connected to over
+a URL:
+
+[source,json]
+----
+{
+ "mcpServers": {
+ "my-integration-app": {
+ "command": "java",
+ "args": ["-jar", "/path/to/my-integration-app-1.0.0.jar"]
+ }
+ }
+}
+----
+
+See the
+https://docs.spring.io/spring-ai/reference/api/mcp/mcp-server-boot-starter-docs.html[Spring AI MCP Server Boot Starter documentation]
+for the transport options and the full list of `spring.ai.mcp.server.*`
+properties. On Quarkus the equivalent setup is described in the
+https://docs.quarkiverse.io/quarkus-mcp-server/dev/getting-started-stdio.html[quarkus-mcp-server stdio guide].
+
+=== Mixing with Spring-defined tools
+
+Camel tools coexist with tools defined natively in Spring AI — both are
+served by the same MCP server and appear in the same `tools/list`. For
+example, a `@McpTool`-annotated bean:
+
+[source,java]
+----
+@Component
+public class CalculatorTools {
+
+ @McpTool(name = "add_numbers", description = "Add two numbers")
+ public String add(
+ @McpToolParam(description = "First addend", required = true) int a,
+ @McpToolParam(description = "Second addend", required = true) int b) {
+ return String.valueOf(a + b);
+ }
+}
+----
+
+is exposed alongside the `ai-tool` routes. Spring-defined tools are
+registered when the server is created; Camel tools are added and removed
+dynamically with the route lifecycle. Choose distinct tool names — MCP has a
+flat tool namespace.
+
+=== Dynamic tools
+
+The exposed tool list follows the route lifecycle: stopping or suspending an
+`ai-tool` route removes its tool, starting or resuming it publishes the tool
+again, and connected clients are notified via
+`notifications/tools/list_changed`:
+
+[source,java]
+----
+camelContext.getRouteController().stopRoute("query-db-route"); // tool disappears
+camelContext.getRouteController().startRoute("query-db-route"); // tool is back
+----
+
+=== Error handling
+
+Results returned to MCP clients are sanitized by the bridge: a route
+exception produces an `isError` result with the generic message
+`Tool execution failed` (the cause is logged server-side and never sent to
+the client), a missing or invalid argument returns the validation message,
+and a call exceeding `camel.mcp-server.tool-timeout` returns
+`Tool execution timed out` while the route keeps running until it completes
+on its own.
+
+On Camel Main and Camel JBang the equivalent setup is the `camel-mcp-server`
+module with the `camel.server.mcp-*` options; on Quarkus it is the
+`camel-quarkus-mcp-server` extension.
+
+== Spring Boot Auto-Configuration
+
+The starter supports 3 options, which are listed below.
+
+[width="100%",cols="2,5,^1,2",options="header"]
+|===
+| Name | Description | Default | Type
+| camel.mcp-server.enabled | Whether to expose ai-tool routes as MCP tools through the Spring AI MCP server. Enabled by default when the starter is on the classpath. | true | Boolean
+| camel.mcp-server.tags | Comma-separated list of ai-tool tags to expose as MCP tools. Only tools registered under one of these tags are exposed; the untagged default pool is never exposed. When not set, no tools are exposed. | | String
+| camel.mcp-server.tool-timeout | Per-call tool execution timeout in milliseconds. A call exceeding the timeout returns an error result to the MCP client; the underlying route keeps running until it completes on its own. | 20000 | Long
+|===
