A guide and tool connection for trading on CSPR.trade, a decentralized exchange on the Casper blockchain. It covers token swaps, liquidity pools, portfolio checks, price history, and optional local transaction signing.

Use it to inspect tokens and pairs, request swap quotes, estimate slippage and price impact, add or remove liquidity, review balances and positions, and submit transactions.

It brings market data, trade preparation, liquidity management, and portfolio checks into one workflow for Casper Network users.

Token cost

What 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 5.1	$0.00040	$0.02378
Opus 5.5	$0.00016	$0.00951
Sonnet 5.5	$0.00008	$0.00476
Haiku 4.5	$0.00004	$0.00238

Security

Grade A, and why

cspr-trade 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 2mo 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.

CSPR.trade DEX Assistant

You have access to the CSPR.trade MCP surface with 22 public tools, plus an optional 23rd tool (sign_deploy) when a local signer is configured. Use this guide to help users trade tokens, manage liquidity, inspect positions, and fetch price history on the Casper Network.

MCP Connection Setup

Main server:

{
  "mcpServers": {
    "cspr-trade": {
      "url": "https://mcp.cspr.trade/mcp"
    }
  }
}

Optional local signer:

{
  "mcpServers": {
    "cspr-trade": {
      "url": "https://mcp.cspr.trade/mcp"
    },
    "cspr-signer": {
      "command": "npx",
      "args": ["@make-software/cspr-trade-mcp", "--signer"],
      "env": { "CSPR_TRADE_KEY_PATH": "~/.casper/secret_key.pem" }
    }
  }
}

Agent flow: build_swap / build_add_liquidity / build_remove_liquidity (remote) → sign_deploy (local) → submit_transaction (remote).

Default deploy handoff is inline JSON. Enable CSPR_TRADE_ENABLE_FILE_DEPLOY_INPUT=true only when both MCP servers run locally and intentionally share temp-file paths on the same machine.

`sign_deploy` reference

If sign_deploy appears in available tools, the local signer is configured. Use it automatically rather than asking the user to sign manually.

What ships with it

16 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
