Topic
Clients, proxies and CLIs that connect coding agents to MCP servers, including how tool schemas are exposed to models.
A dev.to post lists thirteen Python anti-patterns that coding agents keep emitting, then proposes an MCP tool that walks the agent through structured reflections. Ten of the thirteen are single-file static checks.
Reality
The code moved into fastmcp-slim behind client and server extras, and pip -U over 3.2.x does not always re-resolve them. The httpx2 swap breaks a second class of code that still compiles.
Reality
The tools specification dated 2026-07-28 lets a server advertise a cache lifetime for tools/list, which turns every tool name into a contract clients can keep holding well after you deploy a change to it.

Swapping similarity search for a dependency graph took one engineer's review context from 150,000 tokens to 18,000. The saving is file count, not compression, so it holds only where the change sits in a sparse corner of the tree.

MotherDuck's first acquisition buys the runtime that was already executing its agent-written pipelines. The instructive part is what Jordan Tigani says the agents cannot do.
Reality
A dev.to writeup blames multi-hour coding agent failures on session decay rather than model quality, and prescribes disposable sessions over durable state. The memory layer it recommends is its author's own.

AWS has extended Policy in Amazon Bedrock AgentCore to rate limits, prerequisites, ordering and cumulative effects, checked at the gateway rather than requested in a prompt.

An engineering diary for a small MCP client puts numbers on schema bloat in the context window and on the roughly 950 hand-written lines it took to ship with zero dependencies.
