Quick Install
Automated & IDE SetupCopy the AI prompt to install this server into Claude Code, Cursor, or another agent — or use 1-click editor setup below.
One-click editor setup isn’t available for this listing yet — we don’t have a confirmed install command, and we’d rather show nothing than point your editor at the wrong package or host. Follow the project’s own setup instructions, linked above.
Manual Client & Custom JSON ConfigExpand JSON â–¾
No confirmed setup config for this listing yet. We only publish a config block when the install details come from the project itself — its README, its docs, or a verified owner. We haven’t found those for Chamber, and we’d rather show nothing than a guess you’d paste into your client. Follow the project’s own setup instructions for the current steps.
Documentation Overview

Tools
| Tool | Purpose |
|---|---|
chamber_status | cloak try remaining / dead / purchased |
chamber_info | pointer to live prices |
chamber_cloak | seal JSON / text (licensed) |
chamber_open | open sealed blob (keys only) |
chamber_hop_gate | admit/reject hop (gate only) |
chamber_hop_reject_log | live sanitized reject log |
Hop-gate (ScanChunk / Rider SoT)
Admission layer in front of seal/open. Seal/open APIs are unchanged. No SettleHop / x402.
Wire is exact text (Agent-Rider agent-rider-c / PR #22), not JSON:
Fields (allowlist): url · etag · hash · agent_id. Gate result wire is a single exact-text code string (not a JSON body).
| Code | Meaning |
|---|---|
admit | hop allowed |
reject.schema | Chamber-local only (Rider does not emit) |
reject.extra | unknown keys or wrong kind — fail-closed; do not bind; never rehydrate |
reject.hash | empty / invalid hash |
reject.replay | hash already seen |
reject.agent | agent allowlist fail |
reject.empty | empty / missing required fields (url, hash, agent_id) |
Live reject.log is TSV ISO\tcode\tpreview (mirrors agent-rider-c/reject.log); preview truncates ~120 and flattens newlines. Extra-key values never rehydrate as next machine input.
PCC ≠payment — PCC is the compression/storefront face; hop-gate codes are admission control, not billing.
MCP tools: chamber_hop_gate, chamber_hop_reject_log.
