Meta Ads MCP is a Model Context Protocol (MCP) server that lets AI assistants run Meta Ads. Prior to version 1.0.115, AuthInjectionMiddleware in meta_ads_mcp\/core\/http_auth_integration.py rejects HTTP MCP requests only when both auth_token and pipeboard_token are absent, while extract_token_from_headers() does not recognize X-Pipeboard-Token as a primary credential. A network caller using the streamable-http transport can therefore send any X-Pipeboard-Token value, pass the guard without establishing authentication context, and cause get_auth_token() to fall back to the server operator’s META_ACCESS_TOKEN. Subsequent MCP tools execute with the operator’s Meta credentials and can read or modify the operator’s Meta Ads data. Deployments using the default stdio transport or without META_ACCESS_TOKEN are not affected. This issue is fixed in version 1.0.115.<\/p>\n","protected":false},"excerpt":{"rendered":"
