What is CrowdSec?

CrowdSec's 1.8.2 candidates let operators write their own bot fingerprints.

The bot detection introduced with 1.8 is now being opened to customization. The 1.8.2 candidates add custom JavaScript fingerprinting, a cscli bot subcommand and a FlagSubmission helper, and rc2 adds a RateLimit helper for the WAF plus a cookie option for embedded contexts. Operational work runs alongside it: a cs_features metric, optional limits on concurrent decision streams and TLS certificate reloads.

What is SavvyCal?

SavvyCal lets Claude or ChatGPT book and move meetings through an MCP server on every plan.

SavvyCal ships about once a month, and its latest release is the largest in a year: an MCP server on every plan that lets AI assistants find times, book or move meetings, block time and run polls. Earlier releases were contained refinements such as duplicating workflows, locking links before an event, per-event buffers and multi-language booking pages.

5.0

CrowdSec's 1.8.2 candidates let operators write their own bot fingerprints.

◆ Current state

The bot detection introduced with 1.8 is now being opened to customization. The 1.8.2 candidates add custom JavaScript fingerprinting, a cscli bot subcommand and a FlagSubmission helper, and rc2 adds a RateLimit helper for the WAF plus a cookie option for embedded contexts. Operational work runs alongside it: a cs_features metric, optional limits on concurrent decision streams and TLS certificate reloads.

◆ Where it's heading

The WAF remains the center of gravity, and the direction is programmability. RateLimit, SkipProcessing and the fingerprinting hooks give rule authors primitives rather than fixed behavior. The LAPI changes point at larger deployments, where decision streaming puts load on the central API.

◆ Prediction

The final 1.8.2 is dated 26 October on GitHub, though it has not reached this feed yet. Whether fingerprint data ever joins the community blocklist remains unanswered in these notes.

SavvyCal lets Claude or ChatGPT book and move meetings through an MCP server on every plan.

◆ Current state

SavvyCal ships about once a month, and its latest release is the largest in a year: an MCP server on every plan that lets AI assistants find times, book or move meetings, block time and run polls. Earlier releases were contained refinements such as duplicating workflows, locking links before an event, per-event buffers and multi-language booking pages.

◆ Where it's heading

For most of the year SavvyCal has added control for hosts and assistants who schedule for others. The MCP server extends that to software assistants: the same booking and rescheduling actions now work from a chat. That puts SavvyCal's scheduling logic inside other tools instead of only on its booking pages.

◆ Prediction

Expect follow-ups that widen what the MCP server can do, such as more scheduling actions. The single release gives little else to predict from.
