What is Open Babel?

Six years quiet, then a feature release and a fuzzing-driven security cleanup.

Open Babel is a chemical file format conversion and cheminformatics toolkit. After 3.1.0 in 2020 the project went effectively dormant, then returned in May 2026 with 3.2.0 — a release combining real 3D geometry work with the results of a sustained fuzzing campaign run through OSS-Fuzz, with reports from Cisco TALOS, Trail of Bits, and ADA Logics. The 3.2.1 follow-up continues that: a CVE in the MMD parser, sscanf validation across several formats, and a stack overflow in the Gaussian and cube readers.

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.

Open Babel vs Speakeasy: editorial side-by-side

O0.0

Six years quiet, then a feature release and a fuzzing-driven security cleanup.

◆ Current state

Open Babel is a chemical file format conversion and cheminformatics toolkit. After 3.1.0 in 2020 the project went effectively dormant, then returned in May 2026 with 3.2.0 — a release combining real 3D geometry work with the results of a sustained fuzzing campaign run through OSS-Fuzz, with reports from Cisco TALOS, Trail of Bits, and ADA Logics. The 3.2.1 follow-up continues that: a CVE in the MMD parser, sscanf validation across several formats, and a stack overflow in the Gaussian and cube readers.

◆ Where it's heading

The project has re-engaged around two things at once — improving initial 3D structure generation, and hardening the format parsers that make Open Babel useful in the first place. Because it reads dozens of chemical file formats, often from untrusted sources, the parser surface is the attack surface, and the release notes now devote as much space to crash fixes as to chemistry. The project says more bug-fix releases are expected through 2026.

◆ Prediction

Expect continued fuzz-driven parser fixes on the 3.2.x line, since the crash reports arrive from external infrastructure rather than a roadmap.

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.
