Get Transactions by Address

get_transactions_by_address
Read-only
Retrieves native currency transfers and smart contract interactions (calls, internal txs) for an address.
**EXCLUDES TOKEN TRANSFERS**: Filters out direct token balance changes (ERC-20, etc.). You'll see calls *to* token contracts, but not the `Transfer` events. For token history, use `get_token_transfers_by_address`.
A single tx can have multiple records from internal calls.
Requires an `age_from` date to scope results for performance and relevance.
**SUPPORTS PAGINATION**: If response includes 'pagination' field, use the provided next_call to get additional pages.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
age_toNoEnd date and time (e.g 2025-05-22T22:30:00.00Z). Adding this bounds the upper end of the date range started by `age_from`.
cursorNoThe pagination cursor from a previous response to get the next page of results.
addressYesAddress which either sender or receiver of the transaction
methodsNoA method signature to filter transactions by (e.g 0x304e6ade). Filters the (optionally date-bounded) results to a specific method signature.
age_fromYesStart date and time (e.g 2025-05-22T23:00:00.00Z). Alone, returns all transactions to/from the address since this date.
chain_idYesThe ID of the blockchain
session_idNoOpaque session identifier.

Output Schema

TableJSON Schema
NameRequiredDescriptionDefault
dataYesThe main data payload of the tool's response.
notesNoA list of important contextual notes, such as warnings about data truncation or data quality issues.
paginationNoPagination information, present only if the 'data' is a single page of a larger result set.
content_textNoOptional human-readable summary used for MCP content responses.
instructionsNoA list of suggested follow-up actions or instructions for the LLM to plan its next steps.
data_descriptionNoA list of notes explaining the structure, fields, or conventions of the 'data' payload.

A4.7/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Beyond the readOnlyHint/openWorldHint/destructiveHint annotations, the description adds critical behavioral details: token transfers are filtered out, a single transaction can produce multiple records due to internal calls, the age_from requirement for performance, and pagination behavior. This goes beyond the structured annotations and provides valuable context without contradiction.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact yet highly informative, using bold header-like cues for key exclusions and pagination. Every sentence serves a purpose: scope, exclusions, multi-record caveat, required input, and pagination. No filler or redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (7 parameters, output schema present) and the rich annotations, the description covers all essential behaviors: what is retrieved, what is excluded, multi-record behavior, required field, and pagination instructions. It is fully adequate for an agent to select and invoke the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents all parameters with detailed descriptions. The tool description adds minimal extra value for parameter understanding, only reinforcing the age_from requirement and pagination via cursor/next_call. This meets the baseline for high schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool retrieves native currency transfers and smart contract interactions for an address, with an explicit exclusion of token transfers. It distinguishes itself from the sibling tool get_token_transfers_by_address by naming that alternative for token history, so the purpose is specific and well-scoped.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives explicit when-to-use guidance: for token history, use get_token_transfers_by_address instead, and requires an age_from date to scope results. It also explains pagination usage with the 'pagination' field and next_call, providing clear context for when and how to use the tool.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A4.1/5.0
Disambiguation5/5

Each tool targets a distinct blockchain resource or action (address, block, transaction, token, NFT, contract, chain, raw API, session init). Even though direct_api_call is a generic fallback, the specialized tools have clear, non-overlapping purposes, and the complementary nature of tools like get_token_transfers_by_address and get_transactions_by_address is explicitly documented.

Naming Consistency4/5

The majority of tools follow a consistent get_<resource> pattern (e.g., get_block_info, get_tokens_by_address), but there are notable deviations: direct_api_call, lookup_token_by_symbol, inspect_contract_code, read_contract, and __unlock_blockchain_analysis__. These verbs are still descriptive and readable, but the mix of 'get' with other verbs prevents a perfect 5.

Tool Count4/5

With 16 tools, the server is slightly above the ideal 3-15 range but not excessive. Each tool maps to a significant Blockscout API capability, and the count feels proportional to the breadth of blockchain data covered. It is heavier than a minimal toolkit but not bloated.

Completeness4/5

The tool set covers core exploration workflows: address info, block lookup, transaction details, token/NFT holdings, contract ABI/source inspection, and read-only contract calls. Minor gaps like a dedicated token-info-by-contract-address tool exist, but the direct_api_call fallback and get_address_info's token details mitigate these. The surface is comprehensive for a read-only blockchain explorer.
