Croway opened a new pull request, #21594:
URL: https://github.com/apache/camel/pull/21594
# Description
Changes:
- Fix tool provider overwrite bug in AbstractAgent.configureBuilder() by
introducing CompositeToolProvider to compose multiple tool sources
- Add endpoint parameters: mcpClients (bean references) and
mcpServer.\<name\>.\<property\> (inline URI configuration) supporting stdio,
http, and sse transports
- Add dynamic tool exclusion via CamelLangChain4jAgentExcludeTags and
CamelLangChain4jAgentExcludeMcpServers headers
- Add LangChain4jMcpServerDefinition for declarative MCP server config
- Add camel-test-infra-mcp-everything module (SSE transport via
tzolov/mcp-everything-server Docker image)
- Add IT test combining Camel route tools, MCP/SSE and MCP/stdio servers,
and header-based tool exclusion
Example combining Camel route tools with MCP servers on the endpoint:
```
from("direct:chat")
.to("langchain4j-agent:assistant?agent=#myAgent&tags=users"
+ "&mcpServer.everything.transportType=sse"
+ "&mcpServer.everything.url=http://localhost:8585";
+ "&mcpClients=#timeMcpClient")
.to("mock:response");
// Camel route tools
from("langchain4j-tools:userDb?tags=users"
+ "&description=Query user database by user ID"
+ "¶meter.userId=string")
.setBody(constant(USER_DATABASE));
```
Tested the full camel-langchain4j-agent component with:
```
mvn clean verify -Dollama.instance.type=openai \
-Dopenai.endpoint=http://localhost:11434/v1/ \
-Dopenai.model=qwen3-vl:8b-instruct \
-Dopenai.api.key=dummy \
-Dopenai.embedding.model=embeddinggemma:300m
```
# Target

uses the `main` branch)
# Tracking
- [ ] If this is a large change, bug fix, or code improvement, I checked
there is a [JIRA issue](https://issues.apache.org/jira/browse/CAMEL) filed for
the change (usually before you start working on it).
<!--
# *Note*: trivial changes like, typos, minor documentation fixes and other
small items do not require a JIRA issue. In this case your pull request should
address just this issue, without pulling in other changes.
