Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00447 | $0.00447 |
| Opus 5 | $0.00224 | $0.00224 |
| Sonnet 5 | $0.00089 | $0.00089 |
| Haiku 4.5 | $0.00045 | $0.00045 |
Grade A, and why
cursorrules scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
nostr-bray
MCP server + CLI giving AI agents sovereign Nostr identities. 238 tools across 27 groups.
Commands
npm run build— compile TypeScriptnpm test— run all tests (vitest, 1400 tests)npm run lint— type-check (tsc --noEmit)
Architecture
Entry points:
src/index.ts— MCP server (config → IdentityContext → RelayPool → tools → transport)src/cli.ts— CLI wrapper (same handlers, no MCP)
Each tool group: src/<group>/handlers.ts (logic) + src/<group>/tools.ts (Zod schemas + MCP registration).
Groups: identity, social (social/dm/blossom/articles/calendar/badges/communities/groups/wiki/search/scheduled/community-NIPs), trust, relay, zap, safety, signet, vault, util, workflow, dispatch, marketplace, privacy, moderation, handler.
Core modules:
src/context.ts— IdentityContext (nsec-tree root, LRU cache, zeroise, signing)src/trust-context.ts— trust signal aggregation (Signet, WoT, Dominion)src/relay-pool.ts— relay connections, SOCKS5h, Tor policy, write queuesrc/nip65.ts— NIP-65 relay list (signature-verified, TTL cache)src/validation.ts— shared Zod validators (hexId, relayUrl)
Conventions
- British English (colour, initialise, behaviour)
- ESM only
- Commits:
type: description(feat:, fix:, test:, docs:) - No Co-Authored-By lines
- Work on branches, merge to main (semantic-release auto-publishes)
Security Rules
- Never return private keys in tool responses
- Zeroise Buffers in
finallyblocks - Validate all external input via
src/validation.ts - Use
verifyEvent()before trusting Nostr events from relays - Enforce Tor policy on runtime relay additions
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cursorrules is a cursor rule published in the GitHub repository forgesworn/bray (1 stars, last pushed 7d ago), licensed MIT. It adds 447 tokens to every session, about $0.0022 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
