Context Bridge vs Openrouter
A side-by-side look at the Context Bridge and Openrouter MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Context Bridge for conversational ai work as a local process; choose Openrouter for conversational ai as a local process. You can also run both side by side in one mcpServers block.

- You prefer a local stdio subprocess transport.
- You have the keys it needs:
OPENAI_API_KEY, OPENAI_MODEL, OPENAI_BASE_URL, GOOGLE_API_KEY, GROQ_API_KEY, CONTEXTBRIDGE_API_KEY, CONTEXTBRIDGE_HOSTED_URL, CONTEXTBRIDGE_HOSTED_MODEL. - You want tools like
compress_context, format_for_target, resume_context.
Choose Openrouter when
- You need dedicated capabilities in the Conversational AI domain.
- You prefer a local stdio subprocess transport.
- You want tools like

Tools & capabilities
Context Bridge tools 3
compress_contextCompresses a raw transcript into a structured context block.format_for_targetFormats a compressed context block for a destination platform.resume_contextBuilds a destination-ready landing package from a compressed context block.
Openrouter tools 3
list_modelsList LLMs from the OpenRouter catalog (~340 models across all major providers) with normalized $/1M-token pricing, context windows, and modality. Filter by search, free-only, minimum context, or modality (e.g. "image" for vision models). Sorted cheapest-first by completion price. Keyless.get_modelGet full details for one OpenRouter model by id — normalized $/1M pricing (prompt, completion, plus per-request/image/web-search costs), context window, modality, supported parameters, tokenizer, knowledge cutoff. e.g. id "anthropic/claude-sonnet-4.5". Keyless.compare_modelsSide-by-side comparison of pricing ($/1M tokens), context window, and modality for 2-5 OpenRouter models. Answers "is claude-sonnet-4.5 cheaper than gpt-4o". Keyless.
