Marq

By Marq

Marq is a brand templating platform where teams create and distribute on-brand documents like flyers, one-pagers, brochures, datasheets, and social posts. This connector lets Claude read and edit those documents directly: survey a project’s pages, text, images, and smart fields; rewrite, proofread, or translate copy in place; apply a brand kit’s colors, fonts, and logos; populate documents from your Marq datasets; and export finished files as PDF or PNG. Edits respect the template’s existing styling and element locks, so brand and layout integrity hold even when the agent is doing the work.

Maryland Community Compass

By Maryland State Innovation Team, Office of Governor Wes Moore

Maryland Community Compass is the State of Maryland's free neighborhood development platform that centralizes data insights, funding resources, and support to foster thriving businesses and communities statewide, built by the Maryland State Innovation Team in partnership with Anthropic. Since December 2025 it has served over 15,000 active users and helped guide nearly $14 million in state funding to high-need areas. Its MCP server exposes 20 read-only tools that let Claude answer questions about any Maryland address, parcel, or geography. No authentication is required, though requests must come from a US-based network. Find Funding: 2,600+ federal, state, and philanthropic programs aggregated from 100+ sources, spanning grants, loans, tax credits, and technical assistance. One of the most comprehensive databases of public and private funding in Maryland. Full-text search, filters, and profile-based recommendations that help assemble a capital stack for any project. Site Feasibility: parcel-level evaluation across hundreds of federal, state, and local datasets. Property records, Maryland place-based program overlays (Opportunity Zone, Enterprise Zone, Sustainable Community, and more), environmental cleanup sites, historic register listings, conservation easements, green infrastructure, and Baltimore City Vacant Building Notices. Includes full zoning ordinance text for all 23 Maryland counties and 96 municipalities with independent planning authority. Community Plans: nearly 200 published comprehensive, small-area, and neighborhood plans. Search inside any plan (for example, "what does the Fell's Point plan say about parking?") with citation-ready PDF URLs. Neighborhood Insights: 58 census-tract-level metrics (poverty, tenure, cost burden, rental vacancy, permits, and more) with state and county medians for comparison.

Matia MCP

By Matia

Matia is the Unified DataOps Platform for data, AI, and engineering teams, combining ingestion, reverse ETL, observability, and catalog in one place. This MCP gives your agent a single interface to all of it. Because Matia is one unified platform rather than a stack of point tools, the MCP can follow a problem across the entire data lifecycle in a single session. It answers where a number came from and what breaks if you change it, without stitching together separate tools for ingestion, observability, and activation. Works alongside your warehouse MCP, such as Snowflake, so agents move from pipeline health to the underlying data in one flow. Requires a Matia account. Better together. Do more with Matia.

Maven Bio

By Maven Bio

Maven Bio gives Claude real-time structured life sciences data. Drug products, companies, clinical trials, indications, deals, financings, mechanisms, and targets, linked to each other and to the source documents behind them. Ask in plain language. Claude resolves the entity, pulls canonical records, then reads the primary source. "AZD6738" and "ceralasertib" land on the same drug. A landscape query returns the programs in a given indication. A claim about an approval traces back to the FDA letter itself. The Maven Bio connector enables: - Resolving messy names, aliases, and internal codes to canonical entities - Proactively monitoring opportunities: FDA actions, trial readouts, and press releases scoped to the entities a monitor tracks, each signal carrying its source - Discovery by criteria: "Phase 3 KRAS G12C inhibitors," "public oncology companies with late-stage pipelines" - Competitive landscaping by indication, grouped by phase, company, or mechanism - Evidence-based analysis: Search and read FDA filings, SEC filings, clinical papers, press releases, and conference abstracts as full text, structured sections, or extracted citations - Deal benchmarking: Public-company financials, financing rounds, and BD deals filterable by indication - Counts and aggregations across the entity graph Maven Bio MCP server authenticates every call, enforces read-only access and response limits. Users sign in with OAuth 2.1 against their existing Maven Bio identity.
