- HIGHTool poisoning patterns detected
- MEDIUMTool description contains URL to non-standard domainin rpc_call
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
~7,751Tokens (tool definitions)
~4.9 KBTypical response size
Significant attention impact (6.06% of 128k context)
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢read_doc(path, lang)
Read 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_docs(query, lang, limit)
Find 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_chains(chain)
Fetch 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.

Live 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_pricing
Live 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_usage(lines, method, calls_per_day)
Calculate 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'.

}🟢get_method_info(method, chain)
Inspect 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.

}🟢rpc_call(chain, method, params)
Execute 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.
