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 | $0.02456 | $0.02456 |
| Opus 5 | $0.01228 | $0.01228 |
| Sonnet 5 | $0.00491 | $0.00491 |
| Haiku 4.5 | $0.00246 | $0.00246 |
Grade A, and why
fulcra-context-mcp AGENTS.md scanned grade A with 1 finding 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 8d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

AGENTS.md - Context by Fulcra
Context by Fulcra - bridging the gap between agents and humans.
About
Context by Fulcra is a personal data platform that provides humans a place to collect and store real-world personal data - from wearables, calendars, location, medical devices, and more. Hundreds of data sources and types supported. In addition, there are facilities to help users record new free-form data: their own subjective feelings (to record your mood, sleep, etc.) and track progress toward a goal.
Data is primarily collected through the human's phone; the human installs Context by Fulcra and lets the app sync their data to their account.
Interactive Access to the User's Data
The human user gets to investigate their data interactively using beautiful mobile and web apps.
Agentic/Programmatic Access To the User's Data
- Main Developer Docs
- OpenAPI spec
- Python client library and CLI (
pip install fulcra-api): For an easy way to use the client library. Handles authentication for you. It also includes thefulcraCLI, which gives command-line access to the full platform — data queries, the data type catalog, tags, user-defined data types, and file storage. Sub-commands emit JSON lines for piping into tools likejq; runfulcra --helpfor the command list. - MCP server: The endpoint to the public MCP server. The server uses Streamable HTTP transport with OAuth2 authorization. Context users can use this server with their own account to securely access their data.
- MCP server source code: The open-source repository for the MCP server. Useful for inspecting available tools, running locally, or contributing.
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.
