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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00343 |
| Opus 5 | $0.00000 | $0.00171 |
| Sonnet 5 | $0.00000 | $0.00069 |
| Haiku 4.5 | $0.00000 | $0.00034 |
Grade A, and why
cline 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 5d 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.
What it actually says
Cline
Cline supports MCP servers via its VS Code extension settings UI and project-level rules via .clinerules.
Setup
kcp-harness integrate cline
This generates:
cline-mcp-snippet.json (not committed)
Add this via Cline sidebar > MCP Servers tab > gear icon:
{
"kcp-harness": {
"command": "npx",
"args": ["kcp-harness", "serve"],
"disabled": false,
"autoApprove": [
"kcp_plan",
"kcp_trace",
"harness_status",
"harness_session",
"harness_budget",
"harness_temporal_check"
]
}
}
.clinerules (committed)
Governance rules for Cline, including governed paths and mandatory tool usage.
Auto-Approve
The autoApprove list lets Cline call read-only governance tools without a confirmation prompt:
| Tool | Auto-approved | Why |
|---|---|---|
kcp_plan |
Yes | Read-only plan inspection |
kcp_trace |
Yes | Read-only decision trace |
harness_status |
Yes | Read-only status check |
harness_budget |
Yes | Read-only budget query |
harness_temporal_check |
Yes | Read-only drift check |
kcp_load |
No | Loads content — requires approval |
This balances governance visibility (the agent can freely inspect plans and traces) with content access control (loading actual content requires human approval).
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.

cline is an agent published in the GitHub repository Cantara/kcp-harness (0 stars, last pushed 11d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 343 tokens. 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.
