Ctx – Smart Tool Router for AI Agents

An intelligent router that dynamically narrows available tools for AI agents based on the current task, reducing token costs without sacrificing capability. Solves the problem of expensive LLM calls by only loading relevant tools when needed.

Token bloat from over-provisioned tool lists is a real and growing pain point as agentic frameworks like LangChain, LlamaIndex, and AutoGen push developers toward larger tool registries — trimming that context window is a legitimate cost lever, not a vanity feature. No clear incumbent owns this specific layer; most teams are solving it with ad hoc filtering logic baked into their own agents. The $1k–5k/mo revenue band is plausible for a developer tool at early traction, but it implies either a small number of API-based paying customers or a narrow self-serve tier, and neither path scales easily without a consumption or seat model attached to something stickier. The biggest risk is that the major agentic frameworks absorb this functionality natively — LangGraph and similar orchestration layers are already moving toward smarter tool selection, which could make a standalone router redundant within a product cycle or two.
