@fastrevmd-lab fastrevmd-lab released this 06 May 01:00
v0.2.1
02347cc

Sub-project #3 follow-up to v0.2.0. Two new MCP tools and an independent PFE blocklist list. Stdio + remote transport + auth paths unchanged from v0.2.0.

Highlights

  • execute_junos_pfe_command — single PFE-shell call against an explicit FPC target. Wraps as request pfe execute target <fpc> command "<cmd>". Rejects literal " in the input (JmcpError::BadPfeCommand).
  • execute_junos_command_batch — N routers x M operational CLI commands. Parallel across routers (cap = max_concurrent_routers, default 16) via tokio::sync::Semaphore + tokio::task::JoinSet. Sequential per router. Per-command command_timeout (default 360s) and optional whole-batch batch_timeout. Continue-on-error after pre-flight; per-router error rows preserve commands.len() invariant. Result order matches input.
  • Independent pfe_commands blocklist list — under _blocklist_defaults and per-device blocklist. A deny on commands does NOT gate PFE and vice versa. See devices-template.json.

Architecture notes

  • BatchRunner / RouterSession traits (via async-trait) provide a testing seam — production runner wraps rustez::Device; tests use a stub.
  • batch_timeout wraps the JoinSet collect future and synthesizes "batch timeout" rows for routers that didn't report.
  • KNOWN_TOOLS (rust-junosmcp-auth) extended with the two new names. Token files referencing them load only on a 0.2.1+ binary; older binaries reject the file at parse time.

Gating order (unchanged from v0.2.0)

transport → AuthLayer → CallerCtx → tool scope → router scope → blocklist. For batch, router-scope is enforced in a for loop with first-failure short-circuit BEFORE any device I/O.
