Marvnor

Hosted MCP Server for Agent Memory + HTTP API

Marvnor is a proprietary hosted MCP server and HTTP API for agent memory and record-based verification. Store supplied facts as source, relation and target records; ask structured questions against those records and receive TRUE, FALSE or UNKNOWN, with conflicting values flagged. Correct records in place or delete selected records. Send the current question and relevant Marvnor results to your model to write the answer.

Use it to check project dependencies, business states, time-sensitive records and conflicting information. Keep confirmed records between questions and pass only the results needed for the next answer.

Create a test Key · Quickstart · API reference · Recorded demo

Get started

Create a trial Key, then connect your existing AI. Follow the quickstart for setup, the working rule and everyday examples. Five tools handle saving, retrieval, verification, correction and deletion.

MCP endpoint: https://api.marvnor.com/v1/mcp
Authentication: Authorization: Bearer <MARVNOR_API_KEY>

Use one Key per independent project. Your AI saves confirmed or sourced facts and queries Marvnor when it needs project memory. Tasks that do not depend on saved facts stay with your existing AI and tools. Usage test evidence.

Prefer direct HTTP? Run the Python example to save, verify, resolve a conflict, correct and delete its own test data. No SDK or dependencies are required.

Results that show the difference

October 10, 2026 rerun:

Test	Result	What it demonstrates
Two structured record-verification sets	Marvnor: 20/20 in each. DeepSeek text answers across three runs: A 16/20 each; B 14/20, 15/20, 15/20	More accurate judgments on the supplied records, including unknown and conflicting evidence
Final question after 160 turns of synthetic history	Model input: 5,328 to 95 tokens, a 98.2% reduction; both answers correct	Reusable relevant facts sharply reduce repeated model input
Original, shuffled and duplicated facts	420/420 expected verdicts across seven datasets	Stable conclusions despite changes in input order and duplicate evidence
Saved single-value conflicts, tested locally	Both incompatible values flagged; removing one restored support for the other	Conflict management across saved records
Complex logic under 20 concurrent requests	Every request returned 20/20 expected verdicts; median request time 603 ms	Correct batch judgments during the measured concurrent workload

The public suite returned 1,227/1,227 expected verdicts across 62 requests, covering input variants and repeated workloads. Read the report and every comparison question or inspect the data.
