MBrace Therapeutics
MBrace Therapeutics is a privately held, clinical-stage biopharmaceutical company developing antibody-drug conjugates (ADCs) against novel oncology targets. Co-founded by Renata Pasqualini, Ph.D. and Isan Chen, MD, the company builds its pipeline on SPARTA, an in vivo antibody selection and target discovery process it uses to find ADC targets that conventional in vitro discovery misses. Its lead candidate MBRC-101 is an anti-EphA5 monomethyl auristatin E (MMAE) antibody-drug conjugate in a multi-centre, open-label Phase 1/1b dose-finding, safety and pharmacokinetic study in advanced refractory solid tumours; MBRC-201 is in Phase 2, MBRC-301 is in IND-enabling studies against solid tumours, and MBRC-401 is in discovery. MBrace emerged from stealth in November 2023 with an $85 million Series B led by TPG through TPG Life Sciences Innovations, alongside Avidity Partners, Blue Owl Capital, Venrock and Alta Partners, bringing total capital raised to $110 million. MBRC-101 was named Most Promising Clinical Candidate at the 11th Annual World ADC Awards. MBrace Therapeutics runs no developer program and publishes no product API, developer portal, API reference or SDK. The only machine-readable surface reachable without credentials is the WordPress REST content API behind mbracetrx.com, catalogued here — notable because the company registered five of its own custom post types, so its board, executive committee, founders, named investors and scientific advisory board are all published as structured JSON rather than only as rendered HTML.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles MBrace Therapeutics the way a machine reads it — 13 machine-readable artifacts across 9 APIs, 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 — MBrace Therapeutics scores 30.0/100 (thin), with a separate agent-readiness read of 22/100 (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.
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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile MBrace Therapeutics
Each block below is one kind of artifact we hold for MBrace 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 9
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.
MBrace Therapeutics Discovery API
Route, type, taxonomy and status discovery documents.
MBrace Therapeutics Media API
Media library (224 attachments at harvest time).
MBrace Therapeutics News API
Company news archive — press releases, scientific presentations and publications (8 published at harvest time, spanning November 2023 through July 2025).
MBrace Therapeutics Oembed API
oEmbed 1.0 provider endpoint for mbracetrx.com URLs.
MBrace Therapeutics Pages API
Corporate site pages (12 published at harvest time).
MBrace Therapeutics People API

MBrace Therapeutics Search API
Cross-content search across every published object on the deployment (76 searchable objects at harvest time).
MBrace Therapeutics Taxonomy API
Category and tag terms. Four categories are registered; the post_tag taxonomy is registered but empty.
MBrace Therapeutics Users API
Post authors exposed by the users collection (3 at harvest time).

Pricing 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 things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
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 MBrace 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.
