MCP tools · 40 exposed · ~2,743 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 →

Install

How do I install the de.carbon-cashmere.api/crypto-intelligence MCP server?

de.carbon-cashmere.api/crypto-intelligence is a hosted endpoint at https://api.carbon-cashmere.de/mcp/sse, 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 de.carbon-cashmere.api/crypto-intelligence MCP server?

de.carbon-cashmere.api/crypto-intelligence is an MCP server listed in the public MCP registry as de.carbon-cashmere.api/crypto-intelligence. Pay-per-call crypto intelligence: 50 tools, own BTC/Kaspa/Bittensor nodes, x402 USDC, no API key. This page covers its hosted endpoint (https://api.carbon-cashmere.de/mcp/sse).

Is the de.carbon-cashmere.api/crypto-intelligence MCP server safe to use?

de.carbon-cashmere.api/crypto-intelligence scores 29 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 de.carbon-cashmere.api/crypto-intelligence MCP server expose?

de.carbon-cashmere.api/crypto-intelligence exposes 40 tools: kaspa_toccata_status, kaspa_fee_regime, kaspa_throughput_health, kaspa_timeseries, bittensor_subnet_stake_flows, and 35 more. Their descriptions and schemas cost roughly 2,743 tokens of context every time the server is loaded.

Does the de.carbon-cashmere.api/crypto-intelligence MCP server require authentication?

No. We connected to de.carbon-cashmere.api/crypto-intelligence without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the de.carbon-cashmere.api/crypto-intelligence MCP server still maintained?

de.carbon-cashmere.api/crypto-intelligence is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
