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.
npx agentmods add rules/xsidz/ide-bridge/cursorgit clone --depth 1 https://github.com/Xsidz/ide-bridgeWhat it costs to keep this loaded
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 | $0.00256 | $0.00256 |
| Opus 5 | $0.00128 | $0.00128 |
| Sonnet 5 | $0.00051 | $0.00051 |
| Haiku 4.5 | $0.00026 | $0.00026 |
Grade A, and why
ide-bridge cross-IDE context protocol 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
ide-bridge: cross-IDE context protocol (mandatory)
You are connected to an MCP server named bridge. Every Cursor session in this repo must start with a single call to bridge.load_checkpoint. Do this before any other action.
Protocol
- Session start:
bridge.load_checkpoint({ project_id: "<id from .ide-bridge.yaml>" }). Summarise the plan, decisions, todos. - On decision:
bridge.append_decision({ project_id, text, rationale }). - On todo:
bridge.append_todo({ project_id, text }). - Before edits / after sub-tasks / on pause:
bridge.save_checkpoint({ project_id, source_ide: "cursor", bundle_patch: { plan, decisions, todos } }).
Notes
- Read
.ide-bridge.yamlat repo root forproject_id. Do NOT callbridge.get_project_id()without acwdargument. - -32602 responses name the missing argument — fix the call, retry.
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.

ide-bridge cross-IDE context protocol is a cursor rule published in the GitHub repository Xsidz/ide-bridge (7 stars, last pushed 1mo ago), licensed MIT. It adds 256 tokens to every session, about $0.0013 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.
