What is Speakeasy?

Speakeasy stopped inventorying MCP servers and started adjudicating them.

Speakeasy ships near-daily platform releases with unusually legible notes — each headline states what changed for a user, not a version number. The current one turns the Shadow MCP page into a single review surface where every server carries an approval state and an automatically gathered evidence dossier: publisher, requested scopes, declared capabilities, maintenance signals, and whether internal teams already talk to it. Decisions enforce on record. Around it, the assistant surfaces have been consolidating: one detail panel for configuration and observation, exact session totals, and canonical identities folding a person's work and personal AI accounts together.

What is Stirling-PDF?

Stirling PDF is clearing the decks — six weeks of hotfixes ahead of a promised big release.

Every release in this window is corrective. 2.14.3 fixes tool operations failing on Debian 12 and Fedora 44, concurrency problems on merge, an automation bug in image removal, and crashes on 2GB PDFs, plus Linux startup and a Windows ARM64 test build. Before it, 2.14.2 patched Postgres user-data loading, 2.14.1 stopped PostHog loading before opt flags were read and fixed certificate signing, and 2.13.2 covered security fixes and desktop performance. The one feature release is 2.14.0, which added hardware token signing via PKCS#11 smart cards and OS certificate stores on desktop.

10.0

Speakeasy stopped inventorying MCP servers and started adjudicating them.

◆ Current state

Speakeasy ships near-daily platform releases with unusually legible notes — each headline states what changed for a user, not a version number. The current one turns the Shadow MCP page into a single review surface where every server carries an approval state and an automatically gathered evidence dossier: publisher, requested scopes, declared capabilities, maintenance signals, and whether internal teams already talk to it. Decisions enforce on record. Around it, the assistant surfaces have been consolidating: one detail panel for configuration and observation, exact session totals, and canonical identities folding a person's work and personal AI accounts together.

◆ Where it's heading

The arc runs observe, then intercept, now adjudicate. Earlier releases catalogued spend and inventoried shadow MCP servers; the LiteLLM integration moved enforcement to the proxy so a violating prompt dies before inference; this release supplies the judgment layer, doing the research an approver would otherwise do by hand. The supporting work points the same way — prompt-injection scanning of captured skill manifests, risk policies that pause instead of being deleted, identity resolution that reports a whole person rather than an account. Each is a piece a control plane needs before its verdicts can be trusted.

◆ Prediction

Expect approval state to start gating traffic rather than only recording a decision, and the evidence dossier to extend from MCP servers to the skills and assistants already being captured. The rollout flag on the approval workflow suggests general availability is the next step rather than new capability.

S5.0

Stirling PDF is clearing the decks — six weeks of hotfixes ahead of a promised big release.

◆ Current state

Every release in this window is corrective. 2.14.3 fixes tool operations failing on Debian 12 and Fedora 44, concurrency problems on merge, an automation bug in image removal, and crashes on 2GB PDFs, plus Linux startup and a Windows ARM64 test build. Before it, 2.14.2 patched Postgres user-data loading, 2.14.1 stopped PostHog loading before opt flags were read and fixed certificate signing, and 2.13.2 covered security fixes and desktop performance. The one feature release is 2.14.0, which added hardware token signing via PKCS#11 smart cards and OS certificate stores on desktop.

◆ Where it's heading

The project is consolidating a desktop application on top of what was a server tool, and the defect pattern shows where that hurts: platform-specific startup failures, OS certificate integration, ARM64 builds, large-file memory behaviour. Hardware token signing is the strategically interesting piece, since it moves the product toward legally meaningful signatures that a browser-only tool cannot offer. The 2.14.3 notes state a large feature release is two to three weeks out.

◆ Prediction

The changelog explicitly promises a substantial feature release in two to three weeks, and the stabilisation pattern supports that. Hardware token signing spreading beyond desktop-only is the natural extension of the 2.14.0 work.
