Summary
Strips the Copilot-only
toolsfield from the Claude MCP gateway config generated bytransformClaudeEntry. The MCP gateway may attach atoolsfilter for Copilot sessions, but Claude's MCP configuration format does not recognise that field, causing GitHub MCP server registration to fail in Claude sessions.Changes
actions/setup/js/convert_gateway_config_claude.cjsdelete transformed.toolsintransformClaudeEntryto strip the unsupported fieldactions/setup/js/convert_gateway_config_adapters.test.cjstools: ["read"]as input and assert it is absent from output.changeset/patch-strip-copilot-tools-from-claude-config.mdRoot Cause
The shared MCP gateway config may include a
toolsfield scoped to Copilot. When the same config is transformed for Claude, that field is forwarded unchanged. Claude does not supporttoolsin its MCP server entries, so GitHub MCP servers fail to register.Fix
transformClaudeEntrynow explicitly deletestransformed.toolsafter applying its other transformations, ensuring the output is valid for Claude regardless of what the gateway config contains.Test Coverage
Existing unit test updated: input now includes
tools: ["read"]; assertion confirmsconverted.toolsisundefined.
