Federico Mariani updated CAMEL-23948:
-------------------------------------
Attachment: LangChain4jAgentMcpToolProviderFilterTest.java
> camel-langchain4j-agent: mcpToolProviderFilter not applied to endpoint-level
> MCP clients
> ----------------------------------------------------------------------------------------
>
> Key: CAMEL-23948
> URL: https://issues.apache.org/jira/browse/CAMEL-23948
> Project: Camel
> Issue Type: Bug
> Components: camel-langchain4j-agent
> Affects Versions: 4.21.0
> Reporter: Federico Mariani
> Priority: Major
> Attachments: LangChain4jAgentMcpToolProviderFilterTest.java
>
>
> {{AgentConfiguration.withMcpToolProviderFilter(...)}} is honored for MCP
> clients configured on the {{AgentConfiguration}}
> ({{AbstractAgent.configureBuilder}}, lines 115-117), but *ignored* for MCP
> clients configured at the endpoint level:
> {{LangChain4jAgentProducer.createComposedToolProvider}} builds its
> {{McpToolProvider}} without any filter (line 193), covering both the
> {{mcpClients}} URI option and clients materialized from
> {{mcpServer.<name>.*}} definitions.
> The same filter semantics should apply regardless of where the MCP client was
> configured.
> *Fix*: apply the {{AgentConfiguration}} filter (when present) to the
> producer-built {{McpToolProvider}} as well, or introduce an equivalent
> endpoint-level filter option.
> Attached reproducer {{LangChain4jAgentMcpToolProviderFilterTest}} configures
> a filter that rejects every MCP tool plus an endpoint-level MCP client
> advertising one tool: the tool is still advertised to the LLM.
> Related: CAMEL-23928, CAMEL-23929.
