BlockVectra: multi Chain RPC & Data API tools 15
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.- +3 more on the listing page
Pythia Oracle MCP tools 18
list_tokensList all tokens tracked by Pythia with status and reliability info. Returns token symbols, categories, data source count, 30-day uptime, and operational status. Covers cross-chain tokens (BTC, SOL, TAO, RENDER, ONDO, etc.) and DeFi tokens.get_token_feedsGet all available indicator feeds for a specific token. Shows every feed name (EMA, RSI, Bollinger, Volatility across all timeframes), the token's reliability stats, and data source count. Feed names are what you pass to the on-chain oracle to request data. Args: engine_id: Token engine ID (e.g., 'bitcoin', 'solana', 'bittensor', 'aave', 'pol'). Use list_tokens() to see all available IDs.get_market_summaryGet a summary of all tokens tracked by Pythia with operational overview. Returns system-wide stats, tokens grouped by status, uptime distribution, data source health, and infrastructure status. Useful for quickly understanding what Pythia covers and whether the system is healthy.check_oracle_healthCheck the reliability and uptime of Pythia's oracle system. Returns per-token 30-day uptime (sorted worst-first so problems surface immediately), recent daily status history, data source health, and infrastructure status. Use this to verify Pythia's reliability before integrating or relying on its data.get_contractsGet Pythia contract addresses for on-chain integration. Shows all supported chains.get_pricingGet Pythia pricing tiers and free trial info. Prices are live from the data feed.get_integration_guideGet Solidity code to integrate Pythia into a smart contract. Args: tier: 'discovery' (single value), 'analysis', 'speed', or 'complete'. chain: Optional chain key (e.g. 'mainnet', 'amoy', 'arbitrum').
