read_docRead the raw Markdown content of a documentation page from /md/{lang}/{path}.md. Path must be an internal relative path (e.g. 'quickstart', 'guides/ai-agents', 'api/json-rpc', 'chains').search_docsFind documentation by topic or task keywords when the page path is unknown. Searches page titles, navigation titles, relative paths, and page summaries, returning titles, relative paths, and summaries. Read a result with read_doc using its path and the same lang; use read_doc directly for a known path or list_docs to browse the documentation catalog. Omit lang for English; limit is 1-20 (default 5). If no results match, try broader keywords or browse list_docs. Available without an API key.list_chainsFetch supported blockchain networks and static parameters from `GET /v1/chains`. `methods.allow` and `methods.deny` support wildcard patterns where `deny` takes precedence over `allow`. `state_window_blocks` indicates the historical state window in blocks for state queries (null when full history is available); `max_logs_block_range` limits `eth_getLogs`: the range is inclusive, so `toBlock - fromBlock + 1` must not exceed it, otherwise the call fails with `logs_range_too_large`. `public` describes the keyless endpoint: `public.url` serves only the methods in `public.methods`, and `public.history_blocks` is how far back a block reference may reach on that endpoint (it does not add methods). Pass `chain` (a slug such as `base_mainnet`) to return only that chain.get_statusLive operational status and network health from `GET /v1/status`. Confirm chain `status` is 'ok' before calling methods; see `list_chains` for static chain capabilities and method policies. For Data API, `data_status` can be 'ok', 'syncing' (queryable and billed normally, but indexing is lagging behind latest block time), or 'unavailable'.get_pricingLive prices and plan limits from `GET /v1/plans`. Use before estimating cost or when asked about free credits, rate limits or per-method prices. Units: 1 billing unit = `pricing.cu_per_unit` CU; 1 USD buys `pricing.units_per_usd` units. `method_weights` includes JSON-RPC and Data API CU per call, `push.log` / `push.native_transfer` / `push.token_transfer` per delivered data event, `push.history` per successful history request and `push.address_day` per billable address-day; resolve a method by exact match, then the longest prefix rule ending in `*`, then the `*` row (JSON-RPC only; Data API and push operations have no default). `free.*` values are in billing units; `key_defaults` are per-key CU/s and burst CU. `promo.ends_at` is a sign-up coverage cutoff, not the end of the offer. For a single method's chain support and documentation use get_method_info instead; for projecting cycle costs use estimate_usage instead.estimate_usageCalculate projected daily and billing cycle Compute Units (CU) and USD costs for planned call volumes across one or more methods, factoring in method weights and free credit allowances from /v1/plans. Available without an API key. Estimates the API key count for planned traffic under key_defaults. Use this tool for volume budget calculations and capacity planning. For looking up raw system pricing tables, use get_pricing instead. For checking whether a single method is supported on a specific chain, use get_method_info instead. Accepts 'lines' array of {method, calls_per_day} or single 'method' and 'calls_per_day'.how_to_get_api_keyGet instructions and endpoints for obtaining a BlockVectra API key via preferred programmatic SIWE sign-up or browser handoff, plus authentication header and URL formats for JSON-RPC and Data API.get_method_infoInspect a single method's chain-by-chain availability, Compute Unit (CU) weight, price per million calls, and documentation link. Check JSON-RPC method policy and Data API dataset coverage separately. JSON-RPC follows methods.allow and methods.deny from /v1/chains. Data API coverage follows data_features in GET /v1/status, with data enabled in /v1/chains. Pricing comes from /v1/plans. For the full system-wide pricing schedule and rate card, use get_pricing instead. For calculating projected bills for expected call volumes across methods, use estimate_usage instead.explain_errorLookup error code, reason, or HTTP status in the official error reference catalog. Returns meaning, billing implications (whether the call was billed), retryability, retry delay, recommended agent action, and documentation URL.list_docsList all available documentation pages, relative paths, and titles from the static documentation index, including webhook push subscriptions, signatures, delivery and billing. Available without an API key.rpc_callExecute a read-only JSON-RPC 2.0 method on a specified blockchain network using your BlockVectra API key, or via the keyless public endpoint if available on the chain. Chain slugs look like 'base_mainnet'; take them from list_chains. Without a key the call goes to the keyless endpoint `/v1/{chain}/public` (the chain's `public.url` in list_chains), which only serves the methods listed in that chain's `public.methods`. Write methods (such as 'eth_sendRawTransaction') are not supported in rpc_call; use 'send_raw_transaction' instead. Consult the Ethereum JSON-RPC specification (https://ethereum.org/en/developers/docs/apis/json-rpc/) and the BlockVectra method reference (https://docs.blockvectra.com/en/api/json-rpc/methods/). With a key, set the 'x-api-key' or 'Authorization: Bearer <key>' HTTP header in your MCP client configuration for full access (keys must not be passed in tool parameters or chat). Returns the raw JSON-RPC response from the server.data_api_getQuery the BlockVectra Data API for a specified chain and path using your BlockVectra API key. For endpoint schemas and parameter specifications, see the OpenAPI contract at https://docs.blockvectra.com/openapi/data.yaml. Requires the 'x-api-key' or 'Authorization: Bearer <key>' HTTP header in your MCP client configuration (keys must not be passed in tool parameters or chat). Returns the HTTP status and JSON response body.query_contextSearch the Klever VM knowledge base for smart contract development context. Returns structured JSON with matching entries, scores, and pagination. Use this for precise filtering by type or tags; use search_documentation for human-readable "how do I..." answers.get_contextRetrieve a single knowledge base entry by its unique ID. Returns the full entry including content, metadata, tags, and related context IDs. Use this after query_context or find_similar to get complete details for a specific entry.find_similarFind knowledge base entries similar to a given entry by comparing tags and content. Returns related contexts ranked by similarity score. Useful for discovering related patterns, examples, or documentation after finding one relevant entry.get_knowledge_statsGet summary statistics of the Klever VM knowledge base. Returns total entry count, counts broken down by context type (code_example, best_practice, security_tip, etc.), and a sample entry title for each type. Useful for understanding what knowledge is available before querying.enhance_with_contextAugment a natural-language query with relevant Klever VM knowledge base context. Extracts Klever-specific keywords, finds matching entries, and returns the original query combined with relevant code examples and documentation in markdown. Use this to enrich a user prompt before answering Klever development questions.search_documentationSearch Klever VM documentation and knowledge base. Returns human-readable markdown with titles, descriptions, and code snippets. Optimized for "how do I..." questions. Use this instead of query_context when you need formatted developer documentation.analyze_contractAnalyze Klever smart contract Rust source code for common issues. Checks for missing imports, missing #[klever_sc::contract] macro, missing endpoint annotations, payable handlers without call_value usage, storage mappers without #[storage_mapper], and missing event definitions. Returns findings with severity (error/warning/info) and links to relevant knowledge base entries.get_balanceGet the KLV or KDA token balance for a Klever blockchain address. Returns the balance in the smallest unit (for KLV: 1 KLV = 1,000,000 units with 6 decimal places). Optionally specify an asset ID to query a specific KDA token balance instead of KLV.get_accountGet full account details for a Klever blockchain address including nonce, balance, frozen balance, allowance, and permissions. Use this when you need comprehensive account state beyond just the balance.get_asset_infoGet complete properties and configuration for any asset on the Klever blockchain (KLV, KFI, KDA tokens, NFT collections). Returns supply info, permissions (CanMint, CanBurn, etc.), roles, precision, and metadata. Note: string fields like ID, Name, Ticker are base64-encoded in the raw response.query_scExecute a read-only query against a Klever smart contract (VM view call). Returns the contract function result as base64-encoded return data. Arguments must be base64-encoded. Use this to read contract state without modifying it.get_transactionGet transaction details by hash from the Klever blockchain. Returns sender, receiver, status, block info, contracts, and receipts. Uses the API proxy for indexed data.Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.
