"Abstract" matching MCP servers:

A smart proxy server that prevents context window bloat by caching large tool responses to local files and returning compact resource links. It supports format conversion and data uploads, allowing LLMs to handle massive datasets without consuming excessive tokens.

Enables validating and enriching phone numbers, returning validity, international/national formats, carrier, line type, and country/location data.

MCP server for Neo4j that provides abstract graph operations for LLMs, enabling safe and consistent interaction with Neo4j databases through tools like search, insert, update, delete, and schema introspection.

deBridge MCP finds optimal cross-chain swap routes, check fees and conditions, and initiate non-custodial trades across major blockchain networks. Supported: Ethereum, Solana, Arbitrum, Base, BNB Chain, Polygon, Optimism, Avalanche, Linea, Berachain, Tron, Cronos, Gnosis, Monad, Sonic, Flow, HyperEVM, Sei, Story, Injective, Abstract, MegaETH, Mantle, Plasma, Zilliqa, Sophon, Bob, Neon, and more

Enables read-only searching of CNKI literature metadata by topic, keyword, title, author, abstract, or DOI, with filters for year and publication type plus relevance, date, citation, and download sorting. Also retrieves full paper details such as authors, institutions, abstracts, keywords, and references, helping models check whether a research topic has already been studied.

Enables searching EBI BioStudies, a keyless database of biological study descriptions, by keyword and retrieving full metadata for a single study by accession, including title, abstract, release date, and link counts. Results tie studies across EBI archives such as ArrayExpress and PRIDE, so agents can locate and inspect study records without authentication.
