I want to mount a Mitutoyo objective on the front of lenses that have a 77mm filter thread. To keep the objective as close to the lens as possible, I’d prefer a direct adapter rather than stacking step rings. Are there adapters available that go from the Mitutoyo 26mm x 36tpi thread (often listed as M26x0.7) directly to 77mm filter thread, or via common sizes like M42 or 52mm?

Is this what you're looking for? This M26x0.7 (36 tpi, Mitutoyo) female to M77x0.75 male thread adapter at rafcamera.com goes straight from the Mitutoyo mount to 77mm filter size, skipping the M42 mount.

Yes — a direct adapter exists. One community answer points to a Mitutoyo M26x0.7 / 36tpi female to M77x0.75 male adapter, which would let you mount the objective directly to a 77mm filter thread without using intermediate M42 adapters or step rings.
A direct adapter is the best option here because it keeps the objective closer to the lens and reduces the added length and complexity of stacked rings. When shopping, verify both thread standards carefully: Mitutoyo is commonly listed as 26mm x 36tpi (often approximated as M26x0.7), while 77mm filter threads are typically M77x0.75.
