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 5.1 | $0.00055 | $0.03225 |
| Opus 5.5 | $0.00022 | $0.01290 |
| Sonnet 5.5 | $0.00011 | $0.00645 |
| Haiku 4.5 | $0.00006 | $0.00323 |
Grade C, and why
cor-mcp-server scanned grade C with 2 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 1mo 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.

COR MCP Server
What Is COR?
Project COR is a project management platform for creative and professional teams. It provides tools for:
- Project management — Create and manage projects, track budgets, costs, and profitability
- Task management — Assign tasks, set deadlines, track progress
- Client management — Manage clients, contracts, and billing
- Time tracking — Log hours, approve/reject entries, manage timesheets
- Team management — Organize users into teams, allocate resources
- Ratecards & Products — Define pricing and billing structures
- Resource allocation — Allocate team members to projects with percentages and dates
The COR MCP Server wraps the COR REST API (api.projectcor.com/v1) as 61 Model Context Protocol (MCP) tools, making them accessible from any MCP-compatible AI agent.

Technology stack:
- FastMCP (
mcp[cli]>=1.0.0) — MCP server framework - httpx (
>=0.27.0) — Async HTTP client - python-dotenv (
>=1.0.0) — Environment variable management - Python 3.11+ — Async/await throughout
- Dual transport — stdio (for local agents) and SSE/HTTP (for remote access)

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.
- 1mo ago First seen · 310 lines · 55 tokens per session scan C 361930fbd8d5
cor-mcp-server is a skill published in the GitHub repository fxckcode/mcp-cor (0 stars, last pushed 1mo ago), licensed MIT. It adds 55 tokens to every session and 3,225 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
