The security model and runtime requirements are completely different between making an HTTP request and executing arbitrary code. They have different tradeoffs.

What? I get so much joy out of learning the details of careers of people in different industries than me. I had an hourlong conversation with someone the other day who is in the hi…

GP didn't say it's not a problem and not worth fixing. They're claiming this is not a good fix.

> The issue is that "83 per second" is multiple orders of magnitude off the expected level of performance on any RDBMS running on anything resembling modern hardware. This is just …

Americans think "supporting universities" is not necessarily the same as "supporting science."

This comes up every time this conversation occurs. Yes, PG can theoretically handle just about anything with the right configuration, schema, architecture, etc. Finding that right …

There are good arguments for it, but it's also not a coincidence that they happen to align with Google's business objectives. Ex it's hard to issue a TLS cert without notifying Goo…

That will not work with many of the world's most important documents because of information density. For example, dense tables or tables with lots of row/col spans, or complex form…

I write these as part of my job, I know how they work. I'm not going to spend more time explaining to you (and demonstrating!) what is in the spec. Read the spec and let the author…

I'd encourage you to read the MCP specification: https://modelcontextprotocol.io/specification/2025-06-18/ser... Or write a simple MCP server and a client that uses it. FastMCP is …

What you described is essentially how it works. The LLM has no control over how the inputs & outputs are validated, nor in how the result is fed back into it. The MCP interface (Cl…

Every time the LLM uses this tool, the response schema is validated--deterministically. The LLM will never see a non-integer value as output from the tool.

Generally you'd use a time library to model ISO-8601 dates in a typesafe way. Some fancier languages might have syntactic support for it, but they ultimately serve the same purpose…

This is deterministic, it is validating the response using a JSON Schema validator and refusing to pass it to an LLM inference. I can't gaurantee that behavior will remain the same…

I just tried this in Claude Code. I made an MCP server whose tool output is declared as an integer but it returns a string at runtime. Claude Code validated the response against th…

I don't understand this criticism by the author. MCP supports JSON Schema, and server responses must conform to the schema. If the schema requires an ISO-8601 timestamp (ex by spec…
