X Bookmarks — 2025 KW18: Linear ships an MCP server and Polar goes usage-based

@linear — Linear MCP Server

Now online: Linear MCP Server

Give AI models and agents access to your Linear data in a simple and secure way.

That's a smart integration surface. The interesting part isn't the MCP itself but what it signals: Linear is positioning their data layer as something agents can query directly, not just something humans interact with through a UI. If your coding agent can read your current sprint and open issues without a context dump, the planning loop gets meaningfully tighter. Curious how they handle auth scoping — MCP servers that touch project management data need to be careful about what a rogue agent can read or mutate.


@polar_sh — Usage-Based Billing on Polar

Precise, flexible & powerful billing with Polar ✨

Unlock new revenue streams by charging customers for usage within your SaaS. Usage Based Billing is now available on Polar.

Polar keeps shipping the billing primitives that Stripe makes inconvenient to build yourself. Usage-based billing specifically is one of those things that sounds simple until you try to implement it — metering, aggregation windows, overage handling, invoice line items. The fact that Polar wraps all of that and surfaces it alongside their existing checkout flow is genuinely useful if you're a solo developer who doesn't want to maintain a custom metering pipeline. Worth revisiting once they publish docs on how they handle idempotency and late-arriving events.


@audrow — The software engineer career ladder

Software engineer career progression:

  • Intern
  • Junior engineer
  • Senior engineer
  • Staff engineer
  • Farmer

Eleven thousand likes says this hit a nerve. The implication is obvious — at some point you've accumulated enough experience, enough equity, enough of knowing how these organizations work, that you just want land and silence. The 693 replies are basically a taxonomy of career disillusionment. Funny, but also a real signal about how many senior engineers are burned out on the industry's growth-at-all-costs cadence.
