Short Posts

Post 1: plugin security

Agent plugin security is not just dependency security.

It is also tool-surface design.

If an autonomous agent can call the tool, you want:
- narrow actions
- scoped credentials
- per-tool logs
- caller attribution
- kill switches for loops

Broad plugin surfaces are harder to secure and harder to observe.

Post 2: discovery fragmentation

Agent discovery is fragmented because everyone wants to be the registry.

API providers probably need redundant discovery:
- OpenAPI
- agent-readable docs
- llms.txt
- stable tool names
- MCP guide if the API maps cleanly to tools

Do not bet the product on one directory.

Post 3: fewer commerce tools

Shopping agents do not need 200 tools.

They usually need:
- search products
- compare listings
- get best price
- retrieve product details

The hard part is making the data structured and fresh enough that those few tools are actually useful.

Reply 1: security thread

The dependency surface matters, but the tool shape matters too. A narrow, logged, scoped tool surface is much easier to secure than a broad plugin bucket.

Reply 2: discovery thread

I would not bet on one registry winning soon. Providers should make capability discovery redundant: OpenAPI, docs, llms.txt, stable tool names, and MCP only where the mapping is clean.

Reply 3: tool-bloat thread

For vertical use cases, smaller is better. A shopping agent with 4 reliable commerce tools will usually beat one with 150 generic API actions in context.

• Use no link for security-focused posts unless someone asks for examples.
• Use https://api.buywhere.ai/docs when discussing API design or product retrieval.
• Use https://api.buywhere.ai/docs/guides/mcp only in explicitly MCP-focused threads.
