"Free PostgreSQL Database Solutions" matching MCP servers:

MCP server for the STRING protein–protein interaction database, hosted by STRING at mcp.string-db.org. Adapted for LLM grounding: responses are size-limited and include metadata and notes on interpretation and next steps. Tools cover identifier resolution, interaction networks and evidence, functional and PPI enrichment, and sequence similarity search.

Public read-only MCP server providing structured access to Atlarium habitat data and advisory functions for aquariums, terrariums, and related systems.

TransBench is a translational research agent that takes free-text clinical observations, decomposes them into biological axes, generates falsifiable hypotheses grounded in PubMed evidence, and designs reproducible computational experiments with concrete datasets for Claude Science.

Monitors PubMed and medRxiv for configurable research topics, summarizes papers using a local LLM, and stores deduplicated results in a local database.

Enables coding agents to interact with the Reactome pathway database, including search, lookup, hierarchy traversal, SBML/SBGN export, and gene-set enrichment analysis.

Provides direct SQL access to a locally hosted Reactome database, enabling schema discovery, guarded read-only queries, and ergonomic helpers over the full relational schema.

Enables natural language querying of EFSA's OpenFoodTox database containing 8,006 chemical substances with toxicity data, safety assessments, risk limits, and genotoxicity studies for food additives, pesticides, and contaminants.

Search 200M+ patents and scientific literature in natural language using PatSnap's global R&D intelligence database.

MCP server that turns a medRxiv DOI into clean markdown full text and provides free, relevance-ranked preprint search via Europe PMC.

Enables searching biomedical images (X-rays, CT/MRI, clinical photos, etc.) from the Open-i database using natural language queries, returning image results as Markdown links.

Enables LLMs to search LOINC terms with free-text, relevance-ranked, and faceted queries via the LOINC Search API, mirroring the loinc.org/search experience.

Enables AI agents to search Iranian doctors, hospitals and clinics by specialty, city, name, gender and online visit, then read profiles, ratings, insurances, patient reviews, visit prices in Toman and free appointment times. Read-only, with no login, booking or payment, so users compare options and get a profile link to book themselves.

MCP server that provides tools for querying the Human Phenotype Ontology (HPO) including term lookup, hierarchy exploration, cross-ontology mappings, and gene-phenotype-disease associations, all grounded in a local SQLite database for fast offline lookups.

Enables AI agents to search Iranian doctors by speciality, city, neighborhood, insurance and visit type, compare office and online consultation fees, check free appointment times up to a month ahead, and read reviews. Also covers hospitals, clinics, labs, pharmacies, fixed-price clinic offers and health articles, all read-only so booking happens on the site via a returned link.

Enables users to store and query their own medical data—labs, medications, diagnoses, wearables, and food logs—in a local Postgres database and interact with it through any MCP client, with deterministic safety checks.

An MCP server that provides tools for searching and fetching protein data from the UniProt database using the unipressed library.

An MCP server for querying the KEGG bioinformatics database, providing tools, resource templates, and guided prompts for pathways, genes, compounds, and more.

Enables querying the openFDA drug adverse event database for pharmacovigilance work-ups: case searches, counts and demographic/outcome breakdowns, disproportionality measures (ROR/PRR with Mantel-Haenszel adjustment), and empirical Bayes (MGPS/EBGM) signal scores, including bulk screening and stratification by sex, age, or year alongside confounder-adjusted analyses.

Enables searching and retrieving molecular hydrogen medical literature from H2 Papers database, with per-paper safety notes always included in results.
