Dragonfly Therapeutics
Dragonfly Therapeutics is a clinical-stage biotechnology company based in Waltham, Massachusetts, founded in 2016 by Tyler Jacks, Bill Haney and David Raulet to develop natural killer (NK) cell-based immunotherapies. Its proprietary TriNKET (Tri-specific NK cell Engager Therapy) and cytokine engager platforms produce molecules that bind both a tumor or disease antigen and an NK cell activating receptor, recruiting innate and adaptive immunity against cancer, autoimmune disease, fibrosis and neuro-inflammation. Lead clinical candidate DF1001 targets HER2 in advanced solid tumors, and the platform is licensed under multi-target collaborations with AbbVie, Bristol Myers Squibb, Merck and Gilead. Dragonfly is a therapeutics developer rather than a software company: it publishes no developer program, no public API, no SDKs and no machine-readable API contract. The only agent-readable surfaces on its own host are the llms.txt and Model Context Protocol endpoint automatically provisioned by its Wix website platform.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Dragonfly Therapeutics the way a machine reads it — 6 machine-readable artifacts across 1 API, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Dragonfly Therapeutics scores 16.8/100 (emerging), with a separate agent-readiness read of 23/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Why this profile is thin
Dragonfly Therapeutics is a clinical-stage NK-cell immunotherapy developer whose product is a drug pipeline, not software; the whole site is ten Wix pages with no developer, API or docs route, and the only machine-readable surfaces (llms.txt and a /_api/mcp endpoint) are boilerplate auto-provisioned by Wix rather than anything the company authored.
This is an honest zero, not a gap in our research. Dragonfly Therapeutics does not appear to expose an API, so there is nothing here for us to index and nothing for them to fix.

Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Dragonfly Therapeutics
Each block below is one kind of artifact we hold for Dragonfly Therapeutics. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 1
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
Dragonfly Therapeutics Site MCP
Model Context Protocol endpoint served from the Dragonfly Therapeutics website host. This is a platform-provided surface automatically provisioned by Wix for every site it build...
MCP Servers 1
Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

MCP SERVERPricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.

RATE LIMITSSecurity Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

This is an independent, third-party profile of Dragonfly Therapeutics, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
