Dexter MCP — Authenticated Dexter Platform

The authenticated Dexter MCP gives you full access to the Dexter platform through the user's Dexter account. This includes the x402 marketplace tools plus 50+ additional Dexter-native tools for trading, analytics, media, games, and more.

Payment is automatic — the user's managed Dexter wallet handles all x402 settlements without any manual funding step.

x402 Marketplace Tools

These five tools work the same as OpenDexter but with automatic payment through the user's Dexter wallet. No session funding needed.

x402_search — Find paid APIs

Search the x402 marketplace across Solana and EVM chains. Pass the user's job as the query. Use maxPriceUsdc or minPriceUsdc for a hard API invocation-price bound, paidOnly: true for known positive primary USDC prices, and sortBy for relevance, price_asc, or price_desc. Confirm typed controls in appliedConstraints and appliedOrdering. Price order applies inside each relevance tier; strong results remain ahead of related results. The selected endpoint still needs x402_check because alternate payment options can quote a different amount.

x402_check — Preview pricing

Probe an endpoint to see payment requirements per chain without paying. Shows pricing options for each supported chain. Use before x402_fetch to show the user what it'll cost.

x402_fetch — Call and pay automatically

Call any x402 endpoint with automatic payment from the user's Dexter wallet on the appropriate chain. No manual funding — it just works. The user gets the API response directly along with a payment receipt.

x402_wallet — View wallet

Shows the authenticated wallet address and balances. The Dexter managed wallet is pre-funded through the user's account.

Dexter-Native Tools

Beyond the x402 marketplace, the authenticated MCP provides direct access to Dexter's platform tools. These are organized by category:

Solana Trading

• solana_resolve_token: Look up any Solana token by name, symbol, or mint address
• solana_list_balances: Show the user's Solana token balances
• solana_send: Send SOL or SPL tokens to another wallet
• solana_swap_preview: Get a Jupiter DEX quote for a token swap
• solana_swap_execute: Execute a swap through Jupiter

When the user wants to trade, the typical flow is: resolve the token → preview the swap → confirm with the user → execute.

Workflow Patterns

"Swap 10 USDC for SOL"

1. solana_resolve_token for SOL and USDC (get mint addresses)
2. solana_swap_preview with the amounts
3. Show the quote to the user (price, slippage, route)
4. On confirmation, solana_swap_execute

"What's trending on Solana?"

1. onchain_activity_overview for a real-time feed
2. Or search for trending tools: x402_search query "trending tokens"

"Generate a meme about Bitcoin"

1. meme_generator_job with the prompt

"Find me a paid API for sentiment analysis"

1. x402_search query "sentiment analysis"
2. x402_check on the best result
3. x402_fetch to call it

"What are my balances?"

1. solana_list_balances for token balances
2. x402_wallet for the x402 settlement wallet specifically

Tips

• The user is already authenticated. Don't ask them to log in or set up a wallet — it's handled.
• For x402 marketplace searches, quality scores and verification status help the user choose. Highlight verified endpoints.
• For swaps, always preview before executing. Show the user the quote and get confirmation.
• Sora video generation is expensive ($8/job) — mention the price before submitting.
• The marketplace search is fuzzy and supports typos. Search broadly.
