MCP tools · 5 exposed · ~766 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Compare competing interpretations or paths using only caller-supplied evidence. Runs exactly four fixed roles (Operator, Skeptic, Buyer, Adversary) for 1-3 bounded rounds over only the caller-supplied question, context, and evidence. Returns every role position, evidence lineage, structured peer challenges, belief changes, disagreements, falsifiers, deterministic process-integrity results, and one independent Detective Basic audit of the four final conclusions. Does not retrieve outside facts, execute actions, treat peer statements as evidence, or treat majority agreement as truth. Price: 0.25 USD via x402.

Install

How do I install the Batcave Detective Basic MCP server?

Batcave Detective Basic is a hosted endpoint at https://subsidy-stylized-unaligned.ngrok-free.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Common questions

What is the Batcave Detective Basic MCP server?

Batcave Detective Basic is an MCP server listed in the public MCP registry as io.github.Bjorn2-sol/batcave-detective. Evidence-bound second-opinion audit of an agent conclusion against caller-supplied evidence. This page covers its hosted endpoint (https://subsidy-stylized-unaligned.ngrok-free.dev/mcp).

Is the Batcave Detective Basic MCP server safe to use?

Batcave Detective Basic scores 23 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the Batcave Detective Basic MCP server expose?

Batcave Detective Basic exposes 5 tools: evidence_judge, detective_basic, run_python, scenario_council, json_doctor. Their descriptions and schemas cost roughly 766 tokens of context every time the server is loaded.

Does the Batcave Detective Basic MCP server require authentication?

Its publisher declares no required credentials for Batcave Detective Basic. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.

Is the Batcave Detective Basic MCP server still maintained?

Batcave Detective Basic is still listed as active in the MCP registry. We last reached this channel on 22 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
