MCP Security Bench (MSB): Benchmarking Attacks Against Model Context Protocol in LLM Agents

ICLR 2026poster

The Model Context Protocol (MCP) standardizes how large language model (LLM) agents discover, describe, and call external tools. While MCP unlocks broad interoperability, it also enlarges the attack surface by making tools first-class, composable objects with natural-language metadata, and standardi…

A*-Thought: Efficient Reasoning via Bidirectional Compression for Low-Resource Settings

NeurIPS 2025poster

Large Reasoning Models (LRMs) achieve superior performance by extending the thought length. However, a lengthy thinking trajectory leads to reduced efficiency. Most of the existing methods are stuck in the assumption of overthinking and attempt to reason efficiently by compressing the Chain-of-Thoug…

MMFakeBench: A Mixed-Source Multimodal Misinformation Detection Benchmark for LVLMs

ICLR 2025poster

Current multimodal misinformation detection (MMD) methods often assume a single source and type of forgery for each sample, which is insufficient for real-world scenarios where multiple forgery sources coexist. The lack of a benchmark for mixed-source misinformation has hindered progress in this fie…

Video-SafetyBench: A Benchmark for Safety Evaluation of Video LVLMs

NeurIPS 2025poster

The increasing deployment of Large Vision-Language Models (LVLMs) raises safety concerns under potential malicious inputs. However, existing multimodal safety evaluations primarily focus on model vulnerabilities exposed by static image inputs, ignoring the temporal dynamics of video that may induce…

Localize, Understand, Collaborate: Semantic-Aware Dragging via Intention Reasoner

NeurIPS 2024poster

Flexible and accurate drag-based editing is a challenging task that has recently garnered significant attention. Current methods typically model this problem as automatically learning "how to drag" through point dragging and often produce one deterministic estimation, which presents two key limitati…

Learning-to-Rank Meets Language: Boosting Language-Driven Ordering Alignment for Ordinal Classification

NeurIPS 2023poster

We present a novel language-driven ordering alignment method for ordinal classification. The labels in ordinal classification contain additional ordering relations, making them prone to overfitting when relying solely on training data. Recent developments in pre-trained vision-language models inspir…
