Get Token Transfers by Address

get_token_transfers_by_address

Read-only

Get ERC-20 token transfers for an address within a specific time range.
**SUPPORTS PAGINATION**: If response includes 'pagination' field, use the provided next_call to get additional pages.

Input Schema

TableJSON Schema

Name	Required	Description
`token`	No	An ERC-20 token contract address to restrict results to a single token. If omitted, returns transfers of all tokens.
`age_to`	No	End 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`; if omitted, transfers up to the current time are returned.
`cursor`	No	The pagination cursor from a previous response to get the next page of results.
`address`	Yes	Address which either transfer initiator or transfer receiver
`age_from`	Yes	Start date and time (e.g 2025-05-22T23:00:00.00Z). Alone, returns all ERC-20 transfers to/from the address since this date.
`chain_id`	Yes	The ID of the blockchain
`session_id`	No	Opaque session identifier.

Output Schema

TableJSON Schema

Name	Required	Description
`data`	Yes	The main data payload of the tool's response.
`notes`	No	A list of important contextual notes, such as warnings about data truncation or data quality issues.
`pagination`	No	Pagination information, present only if the 'data' is a single page of a larger result set.
`content_text`	No	Optional human-readable summary used for MCP content responses.
`instructions`	No	A list of suggested follow-up actions or instructions for the LLM to plan its next steps.
`data_description`	No	A list of notes explaining the structure, fields, or conventions of the 'data' payload.

A3.6/5.0

Behavior4/5

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

Annotations already indicate readOnlyHint=true and destructiveHint=false. The description adds valuable context about pagination behavior (using next_call when the 'pagination' field appears) and the time-range constraint, going beyond what annotations provide.

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 two concise sentences with the critical pagination instruction prominently bolded. It is well-structured and contains no redundant information.

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

Completeness4/5

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

With 7 parameters and an output schema, the description covers the core purpose and pagination behavior, while annotations handle safety. The main gap is lack of usage guidance relative to sibling tools, but overall the description is sufficiently complete for a read-only list tool.

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 clearly. The description adds a small note about pagination linking to the cursor parameter, but otherwise does not deepen understanding beyond the schema.

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

Purpose4/5

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

The description clearly states it retrieves ERC-20 token transfers for an address within a specified time range, using a specific verb and resource. It is implicitly distinct from siblings like get_transactions_by_address and get_tokens_by_address, but does not explicitly call out those alternatives.

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

Usage Guidelines2/5

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

No guidance is provided on when to use this tool versus similar alternatives (e.g., get_transactions_by_address, get_tokens_by_address). It does not mention exclusions, prerequisites, or typical use cases.

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