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 5.1 | $0.02524 | $0.02524 |
| Opus 5.5 | $0.01010 | $0.01010 |
| Sonnet 5.5 | $0.00505 | $0.00505 |
| Haiku 4.5 | $0.00252 | $0.00252 |
Grade A, and why
agentbridge-protocol AGENTS.md 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 2mo ago.
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.

Project summary
AgentBridge is an AI-native action layer for web apps. Web apps
publish a manifest at /.well-known/agentbridge.json. MCP clients
discover the manifest, validate inputs, enforce confirmation on risky
actions, call action endpoints, and audit the results.
The repo ships:
- Five publishable npm packages plus an MCP server, scoped under
@marmarlabs. - A demo Next.js app and a Studio dashboard.
- A Vitest test suite (86 tests as of v0.2.1).
Current state
- npm scope:
@marmarlabs(do not change). - Latest published release: v0.4.0 on npm and on GitHub (Latest, stable; published via npm Trusted Publishing with SLSA build provenance).
- v0.5.0 is in design — Signed manifests. Design doc: docs/designs/signed-manifests.md; ADR: docs/adr/0002-signed-manifests.md; tracking issue: #31 / docs/issues/v0.5.0-signed-manifests.md. No runtime change yet; implementation lands in subsequent PRs.
- v0.4.0 predecessor PRs: #23 (HTTP transport design), #24 (transport abstraction), #25 (adopter docs/examples), #26 (OpenAPI regression fixtures), #27 (HTTP transport + bearer auth), #29 (release prep), #30 (post-release notes), #28 (SDK public API contract coverage).
- Stdio remains the default and only-when-unset transport. HTTP is
opt-in via
AGENTBRIDGE_TRANSPORT=http. Design in docs/designs/http-mcp-transport-auth.md; ADR in docs/adr/0001-http-mcp-transport.md. - Manifest schema: v0.1, stable for the v0.x line. Will be frozen
for v1.x per docs/v1-readiness.md. v0.5.0
adds an optional
signatureblock; unsigned manifests still validate.
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.

agentbridge-protocol AGENTS.md is an instructions file published in the GitHub repository marmar9615-cloud/agentbridge-protocol (1 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 2,524 tokens to every session, about $0.0101 per session on Opus 5.5. A static security scan graded it A with 0 findings.
