Launch week: every idea card is free.Get Pro

SaaS ideas, mined from what people actually complain about.

Every idea comes from real Reddit posts, was researched against today's competitors, and survived an independent skeptic before it made the list.

MCP Tool Context Bloat

Loading too many MCP tool definitions into context bloats prompts, burns tokens, and degrades tool-selection accuracy.

In their words

agents need to know what tools are available without hardcoding lists

r/mcp on Reddit

notion only allows one mcp connection to one project... notion eats up so much tokens, i get rate limited after a half hour

r/vibecoders_ on Reddit

Context bar was orange before I'd typed a single thing. Tool selection was actively wrong.

r/ClaudeAI on Reddit

Once you pass ~15–20 granular tools into Claude or whatever client you’re running: It clutters the system prompt with schemas.

r/mcp on Reddit

adding more MCP servers/tools eventually creates more problems: tool definitions eat a lot of context, the model has more similar tools to choose between, tool selection becomes less reliable

r/LangChain on Reddit

the tool list is getting messy pretty quickly... the agent starts having too many options. Sometimes it picks the wrong one.

r/MCPservers on Reddit

sessions are starting at ~100k tokens before I type anything, and roughly 70k of that is MCP tool schemas

r/hermesagent on Reddit

Finding a tool that does what the boss needs based on a rough description is hard.

r/CNC on Reddit

Now I wish they'd modularize the other 20k tokens of random tool schemas, most of which I will never use in my workflow.

r/ClaudeCode on Reddit

I run it on 15-20 companies back to back and it starts throttling, just stops getting results

r/AI_Agents on Reddit

Half the time the model sends malformed arguments and there's no way to inspect what actually hit the server.

r/webdev on Reddit

there is a chance that Qwen3.8 can ignore your MCP servers if there is a shell command it can use to complete the task

r/LocalLLaMA on Reddit

ChatGPT effectively forces you to unwrap the entire API into lots of small tools, because each one may need to be authorised separately.

Hacker News

This is the exact problem I'm working around right now in Claude Code, dozens of MCP servers deferred so schemas only load into context

AI agent and MCP developers

Where they talk

  • r/mcp
  • r/MCPservers
  • r/AI_Agents
  • r/LLMDevs
  • r/ClaudeAI
  • r/ClaudeCode
  • r/LocalLLaMA
  • r/LangChain

Tools they use today

  • MCP
  • Claude
  • Claude Code
  • OpenAPI
  • Qwen
  • Docker
  • OpenCode
  • ChatGPT

Why those fall short

  • no layer narrows tool surface per turn; descriptions drift and are undocumented
  • no way to withdraw tools from prior chat history; search still returns too many
  • full tool lists injected whether used or not; no per-tool gating
  • Merging moves ambiguity into argument validity; silent schema mismatches are hard to trace
  • fat tools fail silently; models pick wrong branches
