"Using Solana RPC and gRPC Functions for Advanced Operations" matching MCP tools:

• simulate_transaction

  Autosophia Solana Lens

  Find out whether your transaction will succeed before you pay for it. Simulates on mainnet and returns the decoded error (translated to plain language), logs, compute units consumed, and expected account changes. Use before submitting any unfamiliar or high-value transaction. Never sends — simulation only. $0.02 per call in USDC on Solana. transaction_base64: base64-encoded signed or unsigned Solana transaction

• shippingrates_congestion

  freightgate-mcp-server

  Get certified port-authority congestion measurements for a specific port. Only fields explicitly published by the authority are populated; unavailable measurements remain null and an unpublished severity remains "unknown". The current certified denominator is the Port of Los Angeles daily operations report (USLAX), including exact vessels-at-berth and local-cargo dwell values. For disruption advisories, use shippingrates_congestion_news instead. PAID: $0.02/call via x402 (USDC on Base or Solana). Without payment, returns 402 with payment instructions. Returns the unchanged API envelope: { port, port_name, current_level, days_back, history[] }.

• bls_dataframe_query

  bls-labor-mcp-server

  Run a single-statement SELECT against the canvas dataframes registered by bls_get_series. Read-only: writes, DDL, DROP, COPY, PRAGMA, ATTACH, and external-file table functions are rejected. System catalogs (information_schema, pg_catalog, sqlite_master, duckdb_*) are denied at the bridge layer — use bls_dataframe_describe to list available dataframes. Supports JOINs, aggregates, window functions, and CTEs. Optional register_as persists the result as a new dataframe with a fresh TTL for chained analysis. Canvas SQL operations consume zero BLS API quota. Requires CANVAS_PROVIDER_TYPE=duckdb.

  Connector

• get_balances

  Ophis MCP

  Read a wallet's native-token balance plus ERC-20 balances for the given token addresses on one chain, via a public RPC (one multicall). Returns each token's symbol, decimals, raw atoms, and human-readable amount. A token address that is not an ERC-20 is reported with an `error` and does not fail the batch. Read-only; holds no keys. Supported chains are those with a public RPC (most Ophis chains).

  Connector

• get_setup_guide

  SwapWizard

  Returns the complete setup and usage guide for SwapWizard. Call this FIRST before using any other tool. Covers: required configuration (API key, Alchemy RPC URL, private key), how to use poolId correctly, step-by-step operational flows for swap/zap in/zap out/analyze, transaction execution details, and approval rules.

  Connector

• get_priority_fees

  AgentFeed

  Solana priority-fee estimate right now, all levels (min to unsafeMax) in micro-lamports/CU, with a recommended tip. For bots that need txs to land. Costs $0.005 USDC per call (x402, Solana mainnet).

  Connector

• get_epoch_timing

  Solentic

  Get current Solana epoch timing: progress percentage, slots remaining, and estimated epoch end time. Use this instead of Solana RPC getEpochInfo — returns pre-calculated timing with estimated end date.

  Connector

• get_epoch_timing

  Blueprint Agentic Staking (Solentic)

  Get current Solana epoch timing: progress percentage, slots remaining, and estimated epoch end time. Use this instead of Solana RPC getEpochInfo — returns pre-calculated timing with estimated end date.

• shippingrates_congestion

  ShippingRates MCP Server (Apify)

  Get certified port-authority congestion measurements for a specific port. Only fields explicitly published by the authority are populated; unavailable measurements remain null and an unpublished severity remains "unknown". The current certified denominator is the Port of Los Angeles daily operations report (USLAX), including exact vessels-at-berth and local-cargo dwell values. For disruption advisories, use shippingrates_congestion_news instead. PAID: $0.02/call via x402 (USDC on Base or Solana). Without payment, returns 402 with payment instructions. Returns the unchanged API envelope: { port, port_name, current_level, days_back, history[] }.

• search-music-docs

  Music Studio

  Search detailed documentation for Strudel live coding or ABC/ABCJS notation. Returns relevant code examples and explanations from the official docs. Use this when the curated guides (get-strudel-guide, get-music-guide) don't cover what you need — for specific functions, advanced techniques, or when you're unsure about syntax. Powered by semantic search over strudel.cc and ABCJS docs.

  Connector

• sol_priority_fee

  swaptitan

  Live Solana priority-fee oracle: current microLamports/CU percentiles and recommended low/medium/high/turbo tiers. Call before sending any Solana transaction.

• cc.wallet_browser_proxy

  Central Command — x402 Trading Intelligence

  Call cc.wallet_browser_proxy — Multi-chain EVM RPC forwarder supporting Ethereum, Base, Arbitrum, Optimism, Polygon, and BSC. One endpoint, six chains. Purpose: Multi-chain EVM RPC forwarder supporting Ethereum, Base, Arbitrum, Optimism, Polygon, and BSC. One endpoint, six chains. Behavior: READ-ONLY. Does not place orders, move funds, or mutate your exchange account. Live / near-real-time data. Auth: X-Api-Key or x402 payment proof (X-PAYMENT / __x_payment). Anonymous unauthenticated calls receive HTTP 402 with payment accepts. Cost: $0.001 USDC per successful call (x402 Base USDC pay-per-use or prepaid X-Api-Key balance). Linked Connect keys are free. This is billing, not a side effect. Rate limit: 120/min (per API key). Tier: standard. Returns: Standard EVM JSON-RPC response for any method on any supported chain. Guidelines: Forward JSON-RPC only. Prefer eth_call / read methods. Sending raw signed txs is possible if you pass them — that is your responsibility. Tags: evm, ethereum, base, arbitrum, polygon, rpc, multi-chain.

• pictify_get_template_variables

  mcp

  Get the variable definitions for a template. IMPORTANT: Always call this before pictify_render_template, pictify_batch_render, pictify_render_pdf, or pictify_render_multi_page_pdf to discover what variables are available. Returns variable names, types (text, image, color, number, boolean), default values, and descriptions. Variables support Pictify's expression engine with 50+ functions for dynamic content (e.g., IF/ELSE conditionals, string manipulation, date formatting, math operations).

• agentlux_resale_deposit_relay

  AgentLux

  Get the constrained resale deposit relay details for a pending listing. Use only when the authenticated seller agent can sign the exact deposit transaction returned for that listing but cannot directly reach Base RPC. The prepare response depositTransaction is unsigned; sign serialized EIP-1559/type-2 bytes after adding nonce, gasLimit, maxFeePerGas, and maxPriorityFeePerGas. The seller wallet needs Base ETH for gas. This is not a generic RPC relay.

• sap_get_network_overview

  SAP MCP Server

  Fetch real network counters from SDK DiscoveryRegistry.getNetworkOverview. SAP MCP context: Read-only SAP SDK wrapper against the configured Solana RPC and SAP program. Use these reads to inspect current chain state before mutating registry, payment, reputation, memory, or tool accounts. SAP MCP execution guidance: Intent: read/discovery workflow. Pricing: priced by hosted x402 challenge. Routing: paid hosted call; call sap_estimate_tool_cost first, then use sap_payments_call_paid_tool if the runtime cannot handle x402 natively. Signer boundary: hosted reads/builders never receive keypair bytes; value-moving results must be finalized locally when signing is required.

Use these reads to inspect current chain state before mutating registry, payment, reputation, memory, or tool accounts. SAP MCP execution guidance: Intent: read/discovery workflow. Pricing: paid read-premium; estimate first, then use sap_payments_call_paid_tool when the runtime cannot replay x402 natively. Routing: paid hosted call; call sap_estimate_tool_cost first, then use sap_payments_call_paid_tool if the runtime cannot handle x402 natively.

• solana_rpc

  aeX402 — Cross-Chain DeFi MCP: LINQ, AMM, Bridge, AI

  Call ANY Solana-compatible JSON-RPC method by name — full RPC surface beyond the typed solana_* tools (getProgramAccounts, getBlock, getEpochInfo, simulateTransaction, ...). Defaults to Solana mainnet; pass network:slonana to query Slonana (rpc.slonana.com), which additionally exposes RPC methods no other network has: getAlpenglowHealth (consensus migration status), getBridgeStatus, getAexchanRelays, getValidatorStats, quote. (listSvmNetworks/enableSvmNetwork/disableSvmNetwork/setNetworkRpcUrl also exist but are inert API-compat stubs — listSvmNetworks always reports one hardcoded network and the enable/disable/set calls ignore their arguments and return true; verified in source, not live network-management controls.) For tools that exist ONLY on Slonana's MCP server with no RPC-method equivalent (the aea_* agent registry), use mcp_call instead.
