Direct Caido interaction via the caido-sdk-client Python library, bypassing the Caido MCP server. Prefer this over the caido-proxy MCP skill for efficiency WHEN the SDK is importable in the current runtime. If the import fails, or Caido/the MCP is not loaded, fall back to the caido-proxy skill. For curl-through-Caido testing, match & replace rules, or replay handoffs, use caido-mode instead.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Caido SDK (direct) Talk to a running Caido instance directly through `caido-sdk-client` — one process, no per-call MCP round-trips. Preferred over the `caido-proxy` MCP skill **only when the library is importable**. > **Sibling surfaces.** This capability ships four Caido surfaces against one > instance. Use **this** skill for in-process Python read/replay. For > curl-through-Caido testing, Match & Replace rules, or replay handoff, use > **`caido-mode`**. For tool-call access without writing code, use > **`caido-proxy`** (`caido` MCP for the basics, `caido-go` MCP for batch send, > race windows, intercept, environments, WS). They share `CAIDO_URL`; only > `caido-mode` uses a separate credential store, so none of them clobber each > other's auth. ## Version floor (important) Requires **`caido-sdk-client >= 0.3.0`**. Earlier releases (0.2.x) hardcode the pre-0.57 replay schema — they select `collection`/`activeEntry` on `ReplaySession` and omit `ReplaySessionKind` — so replay calls fail against Caido >= 0.57 with `Unknown field collection on type ReplaySession`. 0.3.0 added the versioned transport split (`transport/latest` vs `transport/v0_56`) and …

How to install
mdr add dreadnode/capabilities/caido-sdk@sha256:58ade2c5d0e9f836The line at the top of this page pins the label git:20260820.c208ec9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
